hello, I was wondering whether 6 gingerol needs to be stored under inert gas? Also what are some of the side effects or risks associate with 6 gingerol coming into contact with skin? thanks in advance

I recently saw a topic on Science Madness about converting Benzoic Acid to Benzamide using Urea. http://www.sciencemadness.org/talk/viewthread.php?tid=4201&p... Can this be done substituting o-Chlorobenzoic Acid? Will it yield o-Chlorobenzamide? Is this a Vapour Phase reaction? If I mix the resulting benzamide with Sulfamic Acid and distill, will that yield o-Chlorobenzonitrile? Thanks for your time

Quiz question regarding a 3,3-dimethyl-bicyclo[4.0.3]nonatetraene: *Picture attached My teacher is insisting that this is an aromatic compound, due to the fact that the pi bond between 1 and 2 can break and form an anion, giving the ring to the left 6 pi electrons to resonate with I simply disagree, since using the same logic would imply a pentalene, for example, would also be aromatic which is commonly held to be antiaromatic. This would contradict the requirement that the delocalization of electrons decreases the energy of the molecule. Any help, explanation, or literature would be appreciated.

Using a patented process I have a tiny amount of dried solubilized keratin, which supposedly can then be used to create fibers. My question is how to preform the later step. In basic terms I broke hair down, took out the keratin, added some "stuff" to it, solubilized and dried it, and now I'm trying to restore it back to fiber form; or at the very least, something more solid than powder. Any help would be much appreciated. 0

I have paradichlorobenzene and I want to make benzene. I have put the crystals in a solution hoping It would make 1,4 phenol. Will that happen? If not could I get a procedure for making a phenol from dichlorobenzene?

hi, i've going through google searching a book called "organic chemistry handbook (Author: hans Beyer, Walter Wolfgang)", i've found one at google books but it´s incomplete. Someone had the book in pdf?. Thanks.

My orginial attempt was not as successful as I had hoped. Any method is welcome. Thanks

In the reaction Aniline + Ethyl acetoacetate ----> bicylic product, is Aniline more likely to react as a nucleophile first at the amine end; by attacking the ketone in ethyl acetoacetate, or is it more likely to be involved in an electrophilic aromatic substitution at the activated ortho position. Textbooks are so bad at these kinds of questions. i.e which is the most reactive part of this given molecule? Thanks for any replies.

I was thinking that the light more towards the violet end of the spectrum would make the plants grow better. I was wondering if this is true?

I want to calculate the HOMO LUMO energy level using cyclic voltammetry, Is there any one have information or reference about this?

I distilled 70% isopropyl alcohol in order to make propene, later propeylene glycol. After the distillation, there was a leftover cloudy, green liquid in my florenece flask. Just curious, what is this green liquid, additives of the propanol? what are they, can they beused for anything? ~ee

Hey guys, I am doing a research project on bio fuels for college and I want to hear your opinion on biofuels. I would be extremely grateful if anyone could answer these questions. I think biofuels are awesome and that we should look use them more instead of fossil fuels, Sure there are disadvantages to using biofuels, They still release C02 and sometimes CO. But I believe the positives out way the negatives. Q1) In your opinion what do you believe to be the best source of renewable energy currently available and can you please explain why? Q2) What is your opinion on biofuels? Do you think that it could be a viable alternative energy supply compared to more trad…

I am wondering generally how hot you can perform an evaporation of an organic substance dissolved in a solvent or other liquid. 1) Does one usually boil the liquid to evaporate it off or heat it only part of the way to boiling and wait? 2)Are there any tips/techniques anyone has for easy and efficient evaporation's? 3) I was assuming some substances will be altered by too much heat while trying to evaporate, is this a fair assumption?

I'm a homescale experimenter/dabbler in the arts of distilling liqueurs/spirits and essential oils, and right now I'm trying to see what vaccuum distillation(at very low temperatures) can add to the finished product as far as taste, aroma, and color go. For my initial experiments, I've been using a simple glass set-up(I can probably get a picture up soon) with a 1000ml boiling flask in a sand bath with a liebig condenser. I've been using an automotive vacuum(for brake lines, etc.) attached to the vacuum take-off valve. I've just been trying to bring ethyl alcohol(everclear) over as an experiment, but I've been having some trouble. I'm hoping this thread can be used to tr…

Hello.. Is there any way to dissolve 2-hydroxybenzyl alcohol in water? Thank you

In Pd(II) catalysed C-H activation of Pyridine, 1, 10-Phenanthroline promote the C3 site selectivity. Is there anyone who can explain this?

I have been working on making benzene starting with benzoic acid form salicylic acid. First I added magnesium powder to a solution of salicylic acid in isopropyl. I was hopping that the Mg would reduce it and make benzoic acid and it would precipitate. Instead the Mg dissolved and over time the solution turned black. What happened, did the benzoic acid dissolve, did it forum magnesium benzoate or salysilate?

I study bismuth compounds and I would like to make sodium bismate. I know it exists but how do I make it? I was thinking you would need sodium hydroxide or bismuth oxide in the process.

I am looking for a list of relatively easy distillations from common chemicals. By "realtively easy" I mean distillations that can be performed with a basic distillation setup + a vigreux column and by "common chemicals" I mean chemicals that I can buy from supermarkets, hardware stores, pool chemicals, etc... By "useful" I mean ideally I would like to be able to use the finished product in some way, for example distilling acetic acid from white vinegar and using it in aspirin synthesis. I just got all the glassware but all I've distilled so far is salt water! My chemistry experience consists of two semesters of inorganic chemistry and two semesters of organic che…

Hi everyone, this is my first post here on your forums. Thanks in advance for your time. Ok, so I'm performing a hydrothermal liquefaction of lignocellulosic material in an aqueous (basic) solvent system. After performing the reaction I am left with an aqueous mixture of; - Solid starting material/char - Base-soluble breakdown products and starting material - Organic solvent soluble breakdown products and starting material I then wish to perform an extraction with diethyl ether (from previous work performed by others both within my lab and elsewhere, diethyl ether and dichloromethane are the only solvents capable of extracting a sufficient range of breakdown produ…

Hello, Does anyone know how to produce 4-Mercaptobenzoic Acid? I guess that it can be prepared from 4-Aminobenzoic acid via diazotization. Can you please correct me if I am wrong and to explain the needed components. I will be very happy if someone can explain this to me. Thanks in advance!

4-nitrophenol + 2-chloro-propanoic acid = ? [1], maybe a 4-nitrophenyl-2-chloropropanoate ester, it's correct? And if [1] + thionyl chloride = ? [2] If [2] + ethylene glycol = ? [3] If [3] + methylisocianate = ? [4] Please! Thanks in advance.

Though it has immense theoretical instability, is it possible to synthesize propyne in incredibly cold conditions....like "liquid hydrogen" cold temperatures. Even if it was possible to synthesize would it foster any benefit? Nobel Prize worthy? ~EE

hi guys. I Want The synthesis method Catalyst [C18H37N(CH3)3]4[H2NaPW10O36] . You can help? thanks.

I recently read a news article about strange and unpleasant additives in food , and one of them was the ANAL SECRETIONS OF A BEAVER ! Now , this begs the question : who tasted a beaver butt to discover that it has a flavor that is similar to raspberries , and therefore would be good in yogurt? How do they figure this out ? Who does this, what is his job title ? Just some of my many practical questions. If this isn't the appropriate forum, please let me know where I can post this . Thanks.
