| Summary: | In this study two major strategy of transformation of the vegetables substrate are exposed. The first approach is related to the study of the catalytic heterocyclisation of natural glycerin in the glycerol carbonate. The system glycerol/glycerol carbonate constitutes a reactional medium of synthon generation and chemical compounds with skelton of multipurpose glycerylic. Glycerol carbonate is a molecule of first generation of the glycerol, it is conceived in natural media as a new chemistry which makes it possible to reinject glycerol in existing or new industry from the orginal procedure by the way of chemical means.
The second approach regards the oleaginous seeds, as substrate in vitro or as microreactor in vivo. This marks a technological breakage compared to the model and tradional process of prapartion of oleochemical bases. In this matter it seems possible to obtain the fatty acids, fatty esters, directly from the oleaginous seeds by interaction between lipids and functional enzymes. This quantitave experimental approach produces the free hydrophobic moity and guarantees the multifonctionnal oleophiles compounds from the renewable oleochemistry. |
