Abstract: Prodn. of 1,2-diacetoxycyclohexane (I) comprises reacting cyclohexene (II) with O2 and acetic acid at elevated temp. in the presence of Ti salt as catalyst. Pref. reaction is at 120-190 degrees C, and the pref. catalyst is Ti acetate. Reaction is esp. at 140-170 degrees C. under 1-100 bar pressure for 15-300 min. The Ti salt is used at 1-15 wt.% on (II) and pref. excess acetic acid is used as solvent. (I) is obtd. simply and with high yield, e.g. at 160 degrees C. productivity is 2800 g./kg. catalyst/hr.

Abstract: Prepn. of alcohols (I) by catalytic transesterification, where (I) has a higher b.pt. than the reactant alcohol (Ia) (and opt. than the ester components), comprises supplying the feed ester, excess (Ia) and catalyst to the upper part of a distillation column, then recovering reaction prods. from the bottom or top of the column. Pref. where the catalyst is a solid it may be used as column packing. The method is esp. for making diols from corresp. esters by reaction with 1-3C monovalent alcohols, specifically prodn. of 1,4-butanediol or 1,4-butenediol from corresp. acetates and methanol. Process can be operated continuously.

Abstract: Diacetates of 1,2-glycols are manufactured by reacting acetic acid with an olefin and oxygen, using oxygen dissolved in the liquid phase of the reaction mixture and avoiding the presence of gaseous oxygen in the reaction space.

Abstract: Alkylene glycol dicarboxylates are obtained by reacting carboxylic acid esters of monohydric or polyhydric aliphatic short-chain alcohols with an olefin and oxygen in the presence of a catalyst, a hydrolyzing agent and water.
