Abstract: A beta-alkoxy-omega-lactam is prepared by subjecting to heating in the liquid phase an omega-amino-beta-alkoxy-carboxylic acid ester. The heating may be carried out at a temperature of 150* to 350*C. If the amino compound is prepared by hydrogenation of the corresponding cyano compound, it is not necessary to separate the amino compound from the reaction mixture. The lactams obtained may be applied for preparation of polyamides and copolyamides.

Abstract: Epsilon -CAPROLACTAM IS RECOVERED FROM A Beckmann rearrangement mixture of the lactam and aqueous sulfuric acid by simultaneously neutralizing the rearrangement mixture with ammonia at a pressure of 1-5 atmospheres and crystallizing out ammonium sulfate, the heat liberated by the neutralization reaction is removed from the system by evaporating a portion of the water from the solution. At the conditions employed hydrolysis of the lactam is substantially reduced if not entirely avoided.

Abstract: A process for manufacturing urea by reacting ammonia and carbon dioxyde is described wherein the ammonium carbamate present in the synthesis effluent is decomposed under high pressure, the gas mixture resulting therefrom is at least partially condensed under a high pressure and the gas-liquid mixture produced in the condensation zone is introduced into the synthesis zone. The ammonia and carbon dioxyde still present in the synthesis solution after the high pressure decomposing of the ammonium carbamate are removed under a low pressure whereby an ammonium carbamate solution is produced, which is used as a washing agent for recovering ammonia and carbon dioxyde from an inerts containing gas mixture discharged from the synthesis zone. The wash solution thus obtained is introduced into the condensation zone, together with a quantity of urea containing solution from the synthesis zone, by means of a jet pump driven by fresh ammonia.

Abstract: Lactams are recovered from a solution of one or more lactams and sulfuric acid in an organic solvent after neutralization with ammonia or an ammonium salt and water without the simultaneous coproduction of solid ammonium sulfate according to the disclosed process. Ammonium hydrogen sulfate produced in the neutralization step is removed in the solution form, preferably concentrated to about 80 per cent by weight and the lactam is recovered from the organic solvent. Removing the ammonium hydrogen sulfate in the solution form rather than a solid avoids crystallization and deposition of the salt onto the surfaces of processing equipment.
