摘要：A process for converting liquid triglycerides into solid triglycerides by means ofrandom transesterification achieved through the use of catalytically active combinationscomprising the reaction product of mixtures of dihydroxy and trihydroxy alcohols withmixtures of alkali metal hydroxides, and with ketones. The catalytically active materialscan be employed in directed transesterifications in which the transesterification reactionmixture is subjected to a series of heating and cooling cycles during which higher meltingfats are formed and precipitated from solution, causing an equilibrium shift that results inthe formation and precipitation of still additional higher melting fats. An especiallydesirable catalytically active combination comprises the reaction product of 1, 2propanediol, 1, 3 propanediol and glycerol, with sodium hydroxide and potassiumhydroxide, and in a preferred embodiment, the reaction product is combined withacetone to form the catalytically active combination.
