摘要:
The invention relates to a process for producing styrene, comprising reacting benzene and acetic acid into methyl phenyl ketone and converting the methyl phenyl ketone into styrene. Preferably, the methyl phenyl ketone is converted into styrene by converting the methyl phenyl ketone into methyl phenyl carbinol and converting the methyl phenyl carbinol into styrene.
摘要:
An osmium-assisted process for the oxidative cleavage of oxidizable organic compounds such as unsaturated organic coumpounds, including alkenes and olefins into aldehydes, carboxylic acids, esters, or ketones. The process uses a metal catalyst comprising osmium and a peroxy compound selected from the group consisting of peroxymonosulfuric acid and salts thereof to oxidatively cleave the oxidizable organic compound. In particular, the process enables aldehydes, carboxylic acids, esters, or ketones to be selectively produced from the corresponding mono-, 1,1-di-, 1,2-di-, tri-, or tetra-substituted olefins in a reaction that produces the result of ozonolysis but with fewer problems. The present invention further provides a process for oxidizing an aldehyde alone or with the osmium in an interactive solvent to produce an ester or carboxylic acid.

摘要:
The present invention relates to a process for preparing aldehydes and ketones by carbon- carbon bond cleavage of alkenes, wherein the process is catalysed by first row transition metal nitro coordinated polyoxometalate catalyst. The catalyst can be prepared by pre-treatment of aqua coordinated polyoxometalates with NO 2 , or they are formed in situ when the reactions are carried in nitroalkanes under aerobic conditions, or they are formed in situ from nitrosyl (NO) compounds in the presence of O 2 .
