How do herbs give medicinal properties into herbal tea/infusions? A lot of medicinally active compounds in herbs are non-polar. An example are terpenes (myrcene, caryophyllene, linalool, limonene, pinene, ...), compounds which are virtually insoluble in water. (a polar solvent) Tinctures use a mixture of water (H2O) and ethanol (C2H5OH) or water and glycerol to solute active compounds of herbs. Ethanol has both polar as apolar properties - so does glycerol - so terpenes can be extracted pretty easily. When I make an infusion of say lavender in water, the active compounds mostly should remain in the flowers as the solvent I'm using when making (h…

how to deal with sticky mass which produced during organic synthesis ?

Can we get metallic magnesium (Mg) from magnesium orotate dihydrate (C10H6MgN4O8)?

For my school exam, i need to make this chemical structure. To prepare the above product, I had thought of a suzuki reaction. My starting products are 1-bromo-2-methylbenzene and (2-Formylphenyl)boronic acid. The performed suzuki reaction can be observed below. Does anyone know if this suzuki response is correct? Would it also be possible to prepare the above product via a different reaction?

I would like to form an ionic solution to electrpolish aluminium alloy from anhydrous aluminium chloride and trimethylamine chloride. The instruction that I am following says, "The liquid was formed by slowly mixing the AlCl3 AR and the TMHC. It was formed in 2h under the protection of a nitrogen atmosphere at 30 degrees C". I am a metallurgist with virtually no inorganic experience. Can anyone tell me what is required? Many thanks.

I am looking to use substitution chemistry to deplete deuterium from drinking water. Studies have shown that light water (deuterium depleted water cures cancer in 25-50% of people with full metastasis and higher rates for regular non-mestasis, non-tumor cancers). Deuterium depletion has been shown to increase T-cell production in the thymus and make all enzymes (10 trillion reactions in human body a day) work better as there is a 1/6000 chance that deuterium will be at a bonding or unfolding site and the enzyme will not work properly, even though 1/6000, that is still 1.666 billion reactions gone wrong or not expressed. DNA polymerase II and III errors lead to uncorrec…

Good day everyone, I wonder if schiff base is stable on TLC plates of aluminum oxide? I know it is hydrolysed on silca gel. How about aliminium oxide?

Good day, I hope you answer my question. 1. I am trying to synthsis schiff base, should I dissolve my reactants? Because they are not totally be dissolved even in hot solvent" ethanol"

Hello, is it possible to draw the ring structure of a ketopentose, like for example D-ribulose? I've been browsing the web and some organic chemistry textbooks, but I haven't been able to find anything. Thanks in advance!

Hi guys. Unfortunatly I must admit I'm a lost case in chemistry. But I love working with fragrances, so I struggle... I just recently worked on a formula with D.P.M. it was the first time I met this stuff and its odor was too strong and unpleasant to me. So I used it in really small amounts. Now I ordered another liter from the same place, and its odorless!! Which I love, but makes me suspect they sent me something else. What do you think? Would very much appreciate an o insight. Talya Ok. I think they sent me D.P.G I hope I posted in the right forum...

Dear all, One of my friend is going to open his own plastic factory and as we may know, we need different pigments, including inorganic pigments and organic pigments and/or solvent dyes in the producing processes, but he knows a little about them, so he turns to me. Even though I have been in the field of pigments and solvent dyes for a few years, but I seldom deal with suppliers. Thus, I post this out and hope you can help us out, thanks. As for the suppliers, I know a little. For example, almost 3/4 suppliers such as Xinghua pigments group are from China, but I heard that their technology is not very advanced which may affect the product qualities; while …

What is the final product of mixing iron nails, water, vinegar and hydrogen peroxide? What is the chemical formula beginning to end? Thanks in advance!

PLEASE, HELP! Suggest ways to detect and remove methylmercury from fish but don't forget that the fish must remain safe for eating. Very necessary!

Hi all! Thanks for the help! I have a sample containing bromine, bromide, and chloride salts in solution with water. I am trying to measure the absorbance of bromide with a photometer for an industrial application. The bromine peak is at 235 nm and the bromide peak is at 214 nm. I thought about automating the phenol red colorimetric method with a reagent system, but chloramine-T is pretty sensitive and would create a lot of waste. I can measure bromine easily, but bromine overlaps with my bromide peak making it difficult to measure bromide. I was thinking if I measure the concentration of bromine first, and then react bromide in such a way to make bromine, I ca…

I need help identifying an unknown in my Organic Chemistry Lab class. I've literally spent 3 hours + on doing research and I'm really stuck... A list of properties: Physical State: liquid Color: golden yellowish / amber Odor: Pungent & Unpleasant; smells almost like ladybugs. pH: 6 => too acidic to be an amine.. right? Boiling Point: ~128 - 129 degrees C Solubility in H20: Soluble Aromatic Flame Test: Black Soot smoke => indicative of a unsaturated compound Beilstein Test for Halides: Negative => no halogens present Ferric Chloride Test for Phenols: Negative Bromine-water test for Phenols: Negative => …

Hello, I read that the concentration of proteins in the blood is 14 meq/L (milli equivalents per liter), but what does an equivalent of protein correspond to? I know that, for exemple, an equivalent of a strong acid is the quantity of that acid that supplies one mole of hydrogen ions, but what about proteins? I'm posting this in the organic chemistry section because we are talking about biomolecules. I hope it's the right section. Thanks in advance!

My old bottle of ethanolamine has turned brown. I wonder if anyone has some experience or suggestions with this. I can get some fresh reagent but I was surprised that this has happened. I suspect that it has been contaminated but I am pretty much the only chemist with access to that so I wonder if it has undergone some interesting reactions. The bottle is over 10 years old. Aldrich reagent grade

I am interested in plastic pollution, particularly microplastics (< 5 mm). This passage is taken from a NOAA document describing recommended methods for microplastic pollution measurement. This is for samples of sea water containing plastic. "The sieved material is dried to determine the solids mass in the sample. The solids are subjected to wet peroxide oxidation (WPO) in the presence of a Fe(II) catalyst to digest labile organic matter. The plastic debris remains unaltered. The WPO mixture is subjected to density separation in NaCl(aq) to isolate the plastic debris through flotation. The floating solids are separated from the denser undigested mineral components…

Hello! Can you tell me please where I can find a complete list of all possible reactions that have glucose as main substrate? It can react with some other simple molecules like O2, H2O, etc. It can be catalytic or enzymatic, but I am looking for the decomposition/conversion reactions, not the polymerisation. Thanks!

I'm hoping for some help in figuring out this problem as it is a bit beyond my scope as a Microbiologist. I'm working with solvent systems and have a system that is 4.8 : 0.2 : 4 : 1 (Heptane. Ethyl Acetate: Ethanol : H20) I'm trying to figure out the percentage mass of each constituent within the solvent systems lower phase..... so it would constitute mainly the Ethyl Acetate/Ethanol/H20 Any help/ guidance would be greatly appreciated.

I came across this Formic Acid 95% Reagent in an online chemical store brumer and I’m wondering if it is suitable as a preservative and antibacterial agent in livestock.

Hello there, I was wondering about the fact that fructose's chain rings up as a furanose...is there any correlation between ketose sugars and furanose rings in general? In other words, do all ketoses form a furanose ring? Thanks!

This will sound very odd but I have been searching for the answer for several years and need someone who know chemistry. I have had IBS-D for 20 years. About 12 years ago I began swimming every other day through my employers wellness program. I also quit using smokeless tobacco. I would start every day with going to the convince store at 6am grab 2 Casey’s General Store premium ring sugar doughnuts, 2 packs of Big Red gum, a bottle of Everfresh O.J. And a Mounds Bar. I would eat the doughnuts and some of the oj on my 20 minute drive to the pool. Swim a slow breast stroke for only 20 minutes. Dry off and drive 5 minutes to my jobs parking lot. Get some big red and put on a…

Hello, bright mind mates! I need to know one thing - and I cant find it in internet (maybe lack of skills) but... Does quinolizidine alkaloids (in particular - Lupanine and Sparteine) formate salts in aqueous solution? And if yes - what kind of them? Thanks for support.

Wondering if there could be any adverse effects from PFAS (per- and polyfluoroalkyl substances) that may affect the integrity/lifespan etc of concrete (esp. foundations)? Whilst I do appreciate that that organic content in cements/concretes, <eg - lime> may act as a preferential sorption media over surrounding soils (depending on the chemistry of the soils), I cannot figure any deleterious integrity impacts to the concrete from the PFAS. When considering construction, I would have thought only real issue is in regard to disposal of concrete at end of life (re: presence of PFAS)). Any assistance appreciated. Thanks.
