Abstract: The present invention provides a process for the separation of a catalyst employed in the epoxidation or hydroxylation of an olefinic compound with a peroxy compound in a reactor, distilling off the epoxidized or hydroxylated product and separation of the catalyst from the distillation residue containing said catalyst and said high boiling organic compounds, said catalyst being a compound of a transition metal, the improvement comprising introducing the distillation residue into a bed of fluidized inert solid particles, burning the organic compounds of said distillation residue with an oxygen containing gas while in contact with said fluidized particles and separating fluidized particles containing a compound of the metal employed in the catalyst from the waste gas of said burning.

Abstract: The present invention provides in a process for producing glycide by reacting allyl alcohol with hydrogen peroxide in the presence of tungsten compounds, distilling the excess allyl alcohol and the major portion of the water in vacuo, dividing the bottom mixture thus obtained at a temperature of from 110 to 220.degree.C and at a pressure of from 5 to 60 torr in a falling-film evaporator into an exhaust vapour consisting primarily of glycide, higher-boiling by-products and the residual portion of the water and a bottom product of glycerin, polyglycerin and the catalyst the improvement in which said exhaust vapour; upon leaving the falling-film evaporator is directly separated into glycide, water and higher boiling byproducts at a pressure of from 5 to 60 torr.

Abstract: The present invention provides a process for producing glycidyl methacrylate which comprises the transesterification of methyl methacrylate with glycide in the presence of a catalyst selected from an alkali metal or an alkali metal compound. The methanol being formed during the reaction being immediately distilled off.
