is widely used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas...
of groups which are known to activate electrophilic substitution in the "meta" position tends to have an adverse effect on our polymerisation and we prefer, therefore, not to use compounds having, for example, nitro, carboxylate, aldehyde, ketone, nitrile, sulphone, sulphate or sulphonate groups....
The invention discloses a mesoporous molecular sieve catalyst, a preparation method thereof and application thereof in preparing aldehyde ketone by gas-phase catalytic selective oxidation of alcohols. The catalyst is marked as Ag-HMS, wherein the molar ratio of SiO2 to silver is 10-500. In the ...
1. Process for the oxidation of an organic olefinic compound into an aldehyde, ketone and/or carboxylic acid which comprises contacting the said organic compound with oxygen in the presence of metallic palladium as catalyst in a liquid medium consisting essentially of 2.5 to 100 percent by volume...
Sometimes, the epoxy groups of a usual and common monomer such as GMA is hydrolyzed by the formation of a vic-diol and oxidized with NaIO4 to create aldehyde groups which can be easily coupled to amine-containing ligands as proteins followed by reduction with NaBH4 or NaCNBH3. Through this,...
Also, we may use such polymers as poly(vinylpyridinium ketones) and haloketones; copolymers of the above-mentioned aldehyde monomers and ketone monomers with or without the above-disclosed copolymerizable comonomers; polyacetal and the like. The molecular weights of the polymers used is not ...
