摘要：Alkanoate esters (I) are prepd. from the corresp. alkanoic acid (II), oxygen and a hydrocarbon (III) by vapour phase reaction at high temp. in the presence of a catalyst system contg. (a) a uranium oxide and (b) one or more arsenic, antimony and bismuth oxides. Process is more economical and less maintenance-intensive than known industrial methods for preparing (I). The prepd. (I) are readily sepd. from the catalyst system. Cpds.
(I) prepd. include ethylene glycol diacetate (a solvent for cellulose esters and ethers, e.g. in resin, lacquer and printing ink formulations), ethylene glycol monoacetate (a solvent for nitrocellulose), allyl acetate and tolyl acetate. The ethylene glycol esters are also plasticisers and intermediates for ethylene glycol.
