Abstract: A process for converting liquid triglycerides into solid triglycerides by means of random transesterification 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.

Abstract: In the process of recovering molybdenum from a spent catalyst solution obtained from a crude reaction product of a molybdenum catalyzed epoxidation of an olefin with an organic hydroperoxide from which crude reaction product epoxide and an alcohol corresponding to the hydroperoxide is removed, the improvement comprises removing and recovering dissolved molybdenum as a high molybdenum content solid by subjecting the spent catalyst solution to a liquid-to-liquid extraction with an aqueous extract to form a two phase system, separating the molybdenum-rich aqueous extract and precipitating therefrom a high molybdenum content solid by heating the aqueous extract in the presence of hydrogen sulfide or a water soluble sulfide salt.

Abstract: A functionalised solid product containing sulphonate or sulphonic acid groups is prepared from an inorganic oxide containing surface hydroxyl groups, e.g. silica by reacting the latter in a first stage with a haloalkyl alkoxy- or arylox- ysilane. The first stage product is then reacted with an aqueous solution of an inorganic sulphite to give a product containing sulphonate groups. These can be converted to sulphonic acid groups by an optional third stage treatment with dilute mineral acid. The final products are suitable for use as adsorbent materials or catalyst supports.
