  • Co-milled mixtures comprising polyol and method of making
    Patent number: 5914320
    Abstract: A process for making a mixture of polyol and at least one additional reaction component for the manufacture of polyol fatty acid polyesters comprises co-milling the polyol and the additional reaction component. The co-milling reduces the particulate size of the polyol and the additional reaction component while creating particles which include an admixture of polyol and the additional reaction component. The co-milled mixture of polyol and additional reaction component can be used, for example, as a feed stream for the transesterfication reaction of the polyol to produce a polyol fatty acid polyester.
