ABSTRACT:
A process for converting liquid triglycerides into solid triglycerides by means of random transesterifications achieved through the use of catalytically active combinations comprising the reaction product of mixtures of dihydroxy and trihydroxy alcohols with mixtures of alkali metal hydroxides, and with ketones. The catalytically active materials can be employed in directed transesterifications in which the transesterification reaction mixture is subjected to a series of heating and cooling cycles during which higher melting fats are formed and precipitated from solution, causing an equilibrium shift that results in the formation and precipitation of still additional higher melting fats. An especially desirable catalytically active combination comprises the reaction product of 1, 2 propanediol, 1,3 propanediol and glycerol, with sodium hydroxide and potassium hydroxide, and in a preferred embodiment, the reaction product is combined with acetone to form the catalytically active combination.
