Polyol composition, process for its preparation and its applications |
摘要 |
The invention relates to a polyol composition exhibiting a very high heat stability and a very high chemical stability, characterized in that it exhibits an optical density lower than or equal to 0.100 in an S test. The invention also relates to a process for the preparation of such a composition, this process consisting in subjecting a polyol syrup to a stabilization stage such as a fermentation, an oxidation or a caramelization, and then to a purification stage. The invention also relates to the application of this composition to the manufacture of products using alkalis or undergoing a heat treatment at high temperature.
