    Abstract: A catalyst composition comprises the reaction product of an alkoxide or condensed alkoxide of a metal M, selected from titanium, zirconium, hafnium, aluminium, or a lanthanide, an alcohol containing at least two hydroxyl groups, a 2-hydroxy carboxylic acid and a base, wherein the molar ratio of base to 2-hydroxy carboxylic acid is in the range 0.01-0.79:1. The composition is useful as a catalyst for esterification reactions, especially for the production of polyesters such as polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate.

    Abstract: Self-heating characteristics of a spontaneously combustible catalyst are reduced by treating spontaneously combustible catalysts with oxygen-containing hydrocarbons having at least 12 carbon atoms. The treatment is particularly suitable for reducing the self-heating characteristics of sulfidable metal oxide(s)-containing catalysts, presulfurized catalysts, presulfided catalysts or reduced catalysts. When applied to sulfur-containing catalysts, the treatment gives a catalyst that has suppressed self-heating properties without substantially compromising sulfur retention or activity. Further hydrocracking catalysts treated by the oxygen-containing hydrocarbons give improved product yield. Further, a method of safely unloading a catalyst from a reactor is provided where the catalyst in the reactor is treated with a liquid mixture containing oxygen-containing hydrocarbon having at least 12 carbon atoms to wet the catalyst.

    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.
