Abstract: An apparatus is disclosed for the preparation of high-molecularweight polymerization products by ionogenic catalytic polymerization of lactams, in which one portion of the monomer is mixed with a catalyst and another portion with a promoter for accelerating the polymerization, after which these two components are mixed in the liquid state at the upper end of a down pipe and introduced into a heated mould in which the polymerization takes place. When charging of the mold is stopped, the down pipe runs empty of the mixture to prevent hardening of the polymer where the mixing takes place.

Abstract: A process for the recovery of lactams from a Beckmann rearrangement mixture of lactams and sulphuric acid or sulphur trioxide, with the production of a phosphate-containing fertilizer is disclosed. The Beckmann rearrangement mixture is partially neutralized by the addition of ammonium or alkali metal hydroxide, sulphate or carbonate in an amount such that the molar ratio between the sulphate formed and the sum of the sulphate formed and the free sulphuric acid is at least 1/8:1. Thereafter, the resulting partially neutralized solution is extracted by a substantially water-immiscible, organic lactam solvent to separate lactam from the remainder of said mixture, and the remainder of said mixture after such extraction is used for the decomposition of rock phosphate with formation of gypsum and of a free phosphoric acid-containing solution. This latter solution, after removal of gypsum and neutralization of the solution with ammonia or alkali liquor is converted into a dihydrogen phosphate-containing solution from which dihydrogen phosphate, suitable for use in fertilizers, is recovered after evaporative concentration. The process provides for the ready separation of lactams from a Beckmann rearrangement reaction mixture, while at the same time producing, as a by-product, dihydrogen phosphate or a valuable dihydrogen phosphate containing fertilizer.
