Abstract: 2-pyrrolidones are prepared by hydrogenating a succinonitrile in the liquid phase in the presence of ammonia by passing an ammoniacal solution of a succinonitrile over a fixed bed catalyst, particularly of the trickle-phase type, in which the catalyst is nickel on an alkaline support such as calcium hydroxide or calcium carbonate. Attractive yields are achieved without the expense of filtering off and separating used catalyst as in prior procedures.

Abstract: Process for the preparation of a porous, pure silica which is particularly suitable as a catalyst support for a chromium-oxide catalyst used in polymerizing of olefins. The process comprises the steps of converting a silicon-halogen compound to a silica and then admixing with water to form a silica gel. The gel is then spray-dried to achieve the required particle size and pore volume.The silica can then be made into a catalyst by placing on the support a chromium compound and then heating in a non-reducing atmosphere.

Abstract: An alkali-metal benzoate is prepared besides benzyl alcohol from a contaminated benzyl benzoate reaction residue obtained in the oxidation of a monoalkyl-benzene compound with a gas containing molecular oxygen. The disclosed process provides for distillation of the contaminated benzyl benzoate in the presence of a basic substance and the resulting distillate is hydrolyzed using an alkali-metal base.In this way, the benzyl benzoate that previously could not be separated from certain tar components by distillation is converted into a pure alkali metal benzoate such as sodium benzoate, besides pure benzyl alcohol, so that a waste product that was previously useless is converted into useful substances.

Abstract: A process for the recovery of 2-pyrrolidone from the aqueous reaction product obtained in the preparation of 2-pyrrolidone from the hydrogenation of succinonitrile and subsequent reaction with water of the hydrogenation product thus obtained. The aqueous reaction mixture is adjusted to a pH value of 7 or lower and extracted with chloroform or methylene chloride to form an organic phase containing substantially all of the 2-pyrrolidone. The 2-pyrrolidone can be recovered from the organic phase by distillation, or by further extraction with water followed by crystallization from the aqueous phase thus formed or by evaporation of water.
