  • Process for the synthesis of polyol fatty acid polyesters
    Patent number: 5079355
    Abstract: The invention pertains to a process for the synthesis of polyol fatty acid polyesters involving transesterification of a reaction mixture comprising a soap emulsifier in which during the reaction at a degree of conversion within the range of from 15 to 60% the soap level is substantially reduced. By this process the high-viscosity and separating-out problems attached to the soap emulsifier in the later stages of the reaction are avoided.
