An ester mixture of dianhydrohexitol, a composition comprising the ester mixture and a polymer composition comprising the ester mixture or the composition, the use thereof, and a process by which the ester mixture can be prepared, where the ester mixture has a mean chain length of (8.3) to (9.2).

Dianhydrohexitol diester mixture NMR

An ester mixture of dianhydrohexitol, a composition comprising the ester mixture and a polymer composition comprising the ester mixture or the composition, the use thereof, and a process by which the ester mixture can be prepared, where the proportion of C8 based on the sum of C8 and C10 in the overall ester mixture is 45 mol % to 85 mol %.

Dianhydrohexitol diester mixture GC

The invention relates to the use of heptyl esters of furan dicarboxylic acid as softeners.

Heptyl esters of furan dicarboxylic acid as softeners

A process for preparing benzoic esters whose alkoxy groups have from 7 to 13 carbon atoms by reacting benzoic acid with at least one alcohol having from 7 to 13 carbon atoms, the water of reaction formed being removed during the esterification reaction by distillation, and the alcohol not converted in the esterification reaction being removed after the esterification reaction, in which the reaction takes place in the presence of a tin(II) compound as catalyst and, without treatment with a base, the catalyst and/or its derivatives is/are separated off by filtering or by centrifuging from the reaction mixture which remains after the unconverted alcohol has been separated off.

Method for producing benzoic acid esters

A tripentyl citrate having an optionally acylated, preferably acetylated, OH group, a process for making the tripentyl citrate, and the use of the tripentyl citrate as a plasticizer for plastics.
