The invention relates to a process ofndioctylsebacate, used as a plasticizernfor plastics or as base oil fornlubricants by the transesterification reactionndimethylsebacate with 2-ethylhexanol, in the ratio ofn1: 2.6, in acid catalysis, and purification of the productnfinal by emptying the vacuum under 10 .20 nun Hg,nat a temperature of 120-140 ° C for 2 hours, andnfiltration. A pure product is obtained overn97.5% and a yield of 98%. |
