POLYOL POLYESTER SYNTHESIS |
| 摘要 |
Polyol polyesters are purified by a process comprising bleaching with a specific silica gel and/or treating with oxygen followed by heat treatment and removal of volatile products by steam deodorization. Any steam deodorization is accomplished at reduced temperatures or in admixture with triglycerides to minimize thermal degradation of the polyol polyesters. |
