摘要:
A process of oxidizing an alcohol for the production of its corresponding carbonyl compounds is disclosed, wherein the oxidation is performed with oxygen or gases containing oxygen in the presence of a catalyst comprising at least a gold compound and a copper compound. Said alcohol oxidation by gaseous oxidant can achieve a high yield and selectivity with minimized degradation products or waste organic solvents.
摘要:
The present invention concerns a process to carry out an ester hydrolysis wherein the ester compound (c) is made from at least an alcohol (a) and a carboxylic acid (b), and wherein said alcohol(a)and said carboxylic acid (b) are forming a biphasic liquid system when mixed together;comprising at least a step of producing an ester compound (c) / water emulsion by using as stabilizing species amphiphilic solid particles of nanometric dimension and optionally a catalyst X.
