Any idea of separating Urea from Formic acid from their mixture? Both are water soluble.

The thought has crossed my mind before but I have never heard of such a material. A quick search omitting sol brought up this article about shark snot which I found pretty interesting. I guess this could be broken down into two major classifications of materials, materials composed of gels that are rich in soluble semiconductor micro-crystals and those whose gels have a semiconductive property. Are there any standard materials that fit into either of these two categories?

Plasticsare the synthetic polymers of carbon, hydrogen and oxygen, derived frompetrochemicals. The two main types of plastics are thermoplastics andthermosets. A large variety of petroleum-based synthetic polymers are producedworldwide to the extent of approximately 140 million tons per year.

Say I have a carbonyl, such as a ketone with two R groups and the double bonded oxygen to the center carbon. Is there another name for the oxygen pi bonded to the center carbon? I call it "d.b. oxygen" for "double bonded oxygen," but I'm looking for a more appropriate name.

Hi, I have a problem figuring out the name of these compounds (see attachment): .mol files are attached in a .zip file. Hope someone can help me with this, sumi mol files.zip

I heard about a process for turning Nitrobenzene to Aniline by refluxing it with NaOH and some Zn causing for Sodium zincate and Aniline to be formed. Then turning the Aniline into Azobenzene, the question is how do you turn the aniline into azobenzene, the simpler the better.

Hi i love inorganic chemistry and have been doing it for a while. But i'm starting to get interested in organic chemistry, I just dont know were to start i dont have any advanced glassware or stuff like that. So can some post some simple organic chemistry experiments for me to do? Thanks

hi! any one has dyes mixing recepie? for getting different shades. specially for acid dyes,direct & reactive dyes.

would directing super-heated steam onto coke produce 'water-gas'?

is there a reason why alcohol is never sold in plastic bottles?

I'm doing research on the phosphonylation of disulfonimides for the synthesis of novel enzyme inhibitors. Has anyone ever done similar research?

would a PTC be absolutely necessary for a beta-chlorination of the propenyl benzenes working with 37% hcl? also would an aprotic non polar solvent be required to eliminate polymerization of the phenylpropene? would gaseous hcl bubbled through the phenylpropene be a better way to go than two phase and PTC? how would this compound then fair under a 10x molar excess of NH3 in MEOH stored at room temp for a week or so? primary amine? expected yeilds? any advice would be much appreciated thanks aminationman

Any one know if Beta-carotene and Lycopene could glow under UV light? I think they are both contain conjugated double bonds, if I'm not sure if it's correct ? Thanks !!!

I've been doing research on Aspirin(Acetylsalicylic Acid). One thing I need to know is about it's solubility in water. I know that Acetylsalicylic acid isn't very soluble in water. I've tried researching on the net and so far i haven't really got it, but I think i'm onto something. Basically I think that Acetylsalicylic Acid isn't very soluble in water because of it's polarity. Water is a polar molecule, and I think Acetylsalicylic Acid isn't. That's all i got so far...:S...so if anyone could help understand it more like how is Acetylsalicylic Acid a non polar molecule?...please do. I really don't think that two line explanation is worth anything. And what would be a good…

I preferably want a practical way to do this not a way that would work on paper. I tried to get a NH2 group on benzene first: ~Benzene + HNO3/H2SO4 ---> Benzene-NO2 ~convert that to an amine by hydrogenation H2/Pd But then I couldnt use a Friedel Craft Acylation to add an aldehyde to the ring because the aryl amine will react with the acyl chloride and make the reaction extremely slow: Benzene-NH2 + CHOCl ---> Benzene-NHCHO but on the other hand, that could be the protecting group to the amine. Is there any other way to add a carboxylic acid onto the benzene ring after that step? <BR class=last-child>any thought is highly appreciated. …

I'm looking to synthesize the product here using the starting material (glucose?) shown below. I'm able to use any reagent but I just can't figure out the steps to do so. Should I open the ring first? Substitute the substituents or . . I'm really stumped here. Any help is appreciated!

Why is it that when you pour oil on to hot water and then try to dissolve salt into it the salt dores not dissolve in it¿

To make a long story short E1 (a protein) reacts with Ubiquitin (another protein) and covalently bonds via a cysteine residue....what type of reaction mechanism are we looking at here? The reaction is ATP dependent if it helps. Thanks a lot in advance.

I'm wondering about the mechanisem of conversion of amine to halide with NaNO2, KBr, H2SO4. I appreciate your assistance,

OK…for as much chemistry as I’ve taken, my High Schooler asked me a question I can’t actually explain…so I’m hoping for help. We were discussing basic chem: the number of bonds for atoms and how they form bonds based on the number of needed electrons in the valence shell. HOWEVER we also discussed how they can transiently form lesser or more bonds than predicted by the periodic table. I.e. H2O regularly picks up transient H+ ions to form H30+ in acidic solutions. And carbon will form a very brief carbocations (carbon with only three bonds and a pos charge) during Sn1 and E1 reactions. Since H20 can relatively readily form transient H3O+ in…

I have a jug of apple cider in the fridge that has semi frozen ie.turned into a liquid/slush but nothing other than it has frozen! is there some odd attribute about apple cider that would explain this phenomenon?

discuss bond order?how to find bond order?

I recieved a ball and stick model set for Christmas. I don't understand why this Glucose is named the way it is. I found information on D-Glucose, but nothing with the + in the middle. Is it the same thing?

I have an organic shark repellent in powder. I would like to formulate cookie size tablets that dissolve in about 4 to 12 hours. Is there a kelp product I can use to bind the powder? I'm ignorant about this. process.

Hello, I was thinking about polarity today and i started thinking about the major factors like electro-negativity of individual atoms, reactions of functional groups and acids, electric fields around an atom.. I came to the realization that I don't REALLY know why any of those effect polarity. my question is if anyone has some interesting facts or detailed explanations about any of those factors? or point me to some links as to any links. For instance how are differences in electro-negativities generated? Thank you for your input.
