Hey all, So I am looking to make some hydrazine sulfate through the ketazine process. However, I don't have acess to the ideal ingredients so I am wondering if my subsitutions would work: 65%Calcium hypochlorite powder susbtituted for NaClO solution 10% concentrated ammonia acetone instead of 2-butanone I would carry out the reaction with excess ammonia and then distill off the dimethyl ketazine from the solution before reacting it with sulfuric acid to get hydrazine sulfate. Are there any problems with this? Thanks in advance!

How to get pure pheophytin a from plant leaves using thin-layer chromatography? I have tried different methods and extracted what I believe to be Pheo a (correct spectrum at room temperature), but it keeps degrading into two substances with very similar spectra (peaks have shifted about 2nm). Unfortunately I do not have access to a mass spectrometer so I do not know what these new substances are. I originally extracted with acetone, then tried ethanol and methanol, but it didn't change a thing. Any ideas? I don't mind reading about methods I have already tried, I'm just trying to make sure I am not re-inventing a bicycle here ;-)

Polytetrafluoroethylene, or Teflon, is wonderful for cooking with. Right now however the people at DuPont are releasing a new and improved version in different colours and probably without the health side effects. However, I am interested to know if Polytetrafluoroethylene can be engineered at the nano level so that not even bacteria can grapple to a surface, this then means that no surface would require anything more than just a wipe of a damp cloth to clean it. Not only this, but of any material or one unlike Polytetrafluoroethylene which could be applied to say toughened glass and used as a kitchen surface. Am I on the right track, basically can bacteria (bad-germs…

does any one know why caspicin (think that is the right spelling) is deactivated by lemon? i found this to be better than milk to rid you of the burning of chillies, does the lemon juice act as a buffer or does the citric acid bind with the spicy alkoid?

I am a rising junior in high school. I aced Honors Chem last year, and I'm taking AP chem this year. Would it be possible for me to do some organic chemistry self-study? I would love to, but I'm not sure if a year of high school chemistry is good enough of a foundation for OC. Thanks, Joe

how would one make haloforms? i have seen the videos and tried to recreate it... but it didn't quite work. help please

Can someone instruct me on how you could possibly make an indicator at home and what colour could be observed in different media of varying pH ? I have hardly any chemica supplies, so this might be a good start! A did a practical at school 2 years ago on making indicator with red cabbage, but I forgot the procedures and requirements. Also can anyone tell me the steps required to make and indicator in order ? What's Universal Indicator made from ? Thnx in advance!

What is meant by this? Is it legit or is it nonsense?

Hey people, I want to run a Fmoc deprotection of my peptide. The point is that I have an azide group in the side chain of the last aminoacid that I attached. Usually I run it with 20% piperidine in DMF but I am afraid about a possible reaction between the azido group and the free amino group after deprotection. I mean, which influence could have piperidine after the Fmoc deprotection in a possible reaction between azide and amino group (piperidine is a nucleophilic base...) Thanks in advance...

I was wondering if anybody knew how titanium butoxide was synthesized? I didn't think just throwing titanium in butanol would work so does anybody have any info on that? I want to use it for synthesizing TiO2 spheres. Thanks!

Why are some aromatic compounds' molecules aren't loose enough, although their structure make them very liable to breaking?

In relation to a project I'm doing at university. I'm stumped on the mechanism of the reactions displayed here. So the first is a rearrangement in sulphuric acid. Afterwards we added crushed ice (well, we add it TO crushed ice of course) Now I don't have a scanner right here so I can't upload my sketches. But it was suggested to me that it might be easier if I flipped over the starting molecule left-to-right. (so the NOH group is on the right) He then suggested that perhaps the N forms a bond with the ring structure now to the left. This would be joined by a protonation of the O group wich would split off as water. I'm not sure this is entirely plausible. …

when polystyrene is dissolved in acetone, is it safe to mould it with your hands without protection? or should rubber gloves or something be worn? i know acetone is used as nail varnish remover and polystyrene is, well, polystyrene, but some people say it's not safe and others say it is so i'm just checking

I have a couple of questions regarding the field and terminology of mass spectroscopy. I think I understand the basic concept of how it works; molecules are ionized, bonds break, and the fragment ions are detected. But one thing I don't understand is that let's say the molecule has a molar mass of 458.37 g/mol; naturally there would be a m/z peak at ~458, that mass since it's the parent ion, but how is it possible for there also to be a m/z fragment at, say, 934.2003. That mass is greater than the mass of the molecule in its natural form. And second; what does the term "MRM transition" refer to? I know that MRM stands for Multiple Reaction Monitoring, but what does it…

Does anybody out there know how to destroy or remove the hydrocarbons in pinesap? I am trying to make homemade amber. I have made copal amber by heating it up, but it is my understanding that it is not true amber because the hydrocarbons are still in the copal. As far as I know no scientist has been able to make true amber in the laboratory. Is that true?

I need to find a method to analyse the clearance of sodium cyanoborohydride throughout a process.. We believe it has been cleared but we are strugglinf to find an assay that will show this with high sensitivity. Does anyone have any suggestions on what could be used?

We have a bacterial structure that may have been made by the addition of putrescine to the OH group of glycerate-2-phosphate (see attached image). What should I call this compound and the enzyme which made the addition? I have seach pubChem but the compound is not in the database.

can anyone give me the name of wax free mineral oil (obtain from petroleum filtration)

Could you create a single sheet of graphene: and then 'hydrogenate' one edge (H-C), whilst 'hydroxylating' the other edge (C-OH), and then 'roll the sheet up' into a tube (center images), allowing the Hs & OHs to 'jump off', as waters, leaving the tube 'sutured together' ??

A pure "Hydro-carbon" comprises a "Carbon-chain backbone", where each interstitial carbon carries 2xH, and the terminal carbons are "capped" by H: H-,C'-,C'-...-,C'-H (,C' = H-C-H) Hydro-carbons are named "number-ane" (e.g., hexane). A pure carbo-Hydrate -- what I would want to call a "Hydroxl-carbon" -- comprises the same sort of Carbon-chain backbone, but each interstitial carbon carries H+OH (and the terminal carbons are, again, "capped" by H): H-,C"-,C"...-,C"-H (,C" = H-C-OH) Hydroxl-carbons (carbo-Hydrates) are named "number-ose" (e.g., hexose), where some of the middling carbons carry 2xH, and others H+OH ?? Is there such a thing, as…

Some cases polymer i.e rubber sheets are used as insulator. People assumes that rubber is an insulator. rubber can be made insulator or conductor. My question is what is the minimum gap required to use it as best insulator( for DC application)? What is the evidence?

This is the first i am using a forum i have a question that can any one tell me the chemical name of PHENOLIC RESIN used in LAUNDRY INK manufacturing

can sulfur attack at oxygen acting as an electrophile??

Is this even possible? It seems like horsecrap. He said his skin was reddish-brown. \ (Cite Sources Please)

I have been trying to balance this equation... I have balanced all the elements on both sides of the equations besides H's and O's and once I balanced the H's, I can't seem to balance the O's to make the whole equation equal! Step-by-step would be greatly appreciated! ?Cu(s) + ?HNO3(aq) -> ?Cu(NO3)2(aq) + ?H2O(l) + ?NO(g) And this is the same thing too for this equation, somehow I get stuck with the H's. Am I doing the process wrong? S2Cl2 + NH3 -> N4S4 + NH4Cl + S8 Thank you so much in advance! C
