Abstract: Polyester is produced by reaction of an aliphatic dicarboxylic acid, neopentyl glycol, at least one other diol, and a nonanol mixture comprising mainly 1-nonanol, monomethyloctanols, dimethylheptanols and monoethylheptanols. An Independent claim is also included for the nonanol mixture.

Abstract: Production of an ester (I) from alcohol (II) and carboxylic acid (III) involves (a) passing a mixture containing (II) and/or (III) into a distillation column with separate zones for reactive inserts (A) below, and conventional inserts (B) above, the inlet; (b) reacting (II) with (III) on the reactive inserts in the presence of a catalyst; (c) separating the reaction mixture into higher-boiling (I) in the reboiler and lower-boiling azeotrope of (II), water and (I) at the top; and (d) phase separation of the azeotrope into an organic phase, which is recycled, and an aqueous phase. Specifically, (i) a heterogeneous catalyst is used in stage (b); and (ii) (I) is discharged as pure product above the reboiler inlet and between other conventional inserts (C), which are different from inserts (B). Also claimed is the plant used in the process.

Abstract: Pure monoesters of adipic acid are prepared by a process in which (a) a pentenoate is reacted with carbon monoxide and hydrogen at from 90 DEG to 140 DEG C. and under from 5 to 300 bar in the presence of a carbonyl complex of cobalt or of rhodium, and a 5-formylvalerate is separated off, and (b) the 5-formylvalerate thus obtained is oxidized with molecular oxygen, or with a gas containing this, at from 20 DEG to 100 DEG C. under from 1 to 10 bar.
