SYNTHESIS OF TRIETHYLENE GLYCOL BIS(2-ETHYLHEXANOATE)

A process for the transesterification of methyl-2- ethylhexanoate with triethylene glycol to produce triethylene glycol di-2-ethylhexanoate is provided. In the process, methyl-2- ethylhexanoate is combined with triethylene glycol to form a first mixture. The first mixture is heated in the presence of a catalyst to form a second mixture comprising methanol and triethylene glycol di-2-ethylhexanoate. Methanol is separated from the second mixture to yield triethylene glycol di-2-ethylhexanoate. Na2CO3, CS2CO3, K2CO3, Rb2CO3, sodium methoxide or titanium isopropoxide are suitable catalysts.

Process for synthesizing fatty acid ester through tin oxide catalysis (by machine translation)

The catalyst is used in the high-grade fatty acid ester reaction, and the catalyst can be separated from the product after the reaction is finished, so that the catalyst can be repeatedly used. (by machine translation)

PROCESS FOR PREPARING CARBOXYLIC ACID ESTERS IN THE PRESENCE OF A TITANIUM-CONTAINING CATALYST

?The present invention relates to a process for preparing carboxylic acid esters, comprising esterification of a carboxylic acid with an alcohol in the presence of a titanium-containing catalyst selected from compounds of a general formula, Tin(OR)x(OR')xOy, wherein n is an integer from 1 to 4; у is an integer from 0 to 6; x can be the same or different and is an integer from 2 to 8; R is a linear or branched C1-C18alkyl, C3-C18cycloalkyl, R' is aryl optionally comprising an electron-donor substituent; or a mixture thereof, with the proviso that if n is 1, then x is 2 and у is 0; and if n>1, then the compounds comprise at least two alkoxy groups and two aryloxy groups. The present invention also relates to a process for preparing carboxylic acid esters, wherein a compound of general formula (I) or (II), wherein q represents an integer of 1 to 4; Y is independently R or R'; or a mixture thereof, with the proviso that the compounds comprise at least two alkoxy groups and two aryloxy groups, is used as a catalyst. The claimed process allows to reduce the amount of a used catalyst and the time of the process duration, while increasing the conversion rate of initial reagents and the yield of a target product.
