Abstract: Procedimientos para la separacion extractiva de complejos de níquel (0) con ligandos y/o ligandos libres fosforados del producto de una reaccion de hidrocianacion de mononitrilos insaturados para obtener dinitrilos por extraccion mediante un hidrocarburo, donde se lleva a cabo la separacion de fases del hidrocarburo y del producto de la reaccion en dos fases, a una temperatura T (en sC) caracterizado porque el contenido de complejos de níquel (0) con ligandos fosforados y/o ligandos libres fosforados del producto de la reaccion de hidrocianacion es, segun la temperatura T, de por lo menos y % en peso, y es independiente de la temperatura T, como máximo de 60% en peso, siendo dado el valor numérico del contenido mínimo y por la ecuacion y = 0,5 ò T l 20 y T debe usarse en la ecuacion como valor numérico adimensional.

Abstract: Producing 3-pentenonitrile comprises isomerizing a 2-methyl-3-butenonitrile feed stream in the presence of a dissolved or dispersed catalyst, distilling the product stream to separate an overhead stream (2) from a catalyst-containing bottoms stream, distilling stream (2) to obtain an overhead stream enriched in (Z)-2-methyl-2-butenonitrile and a bottoms stream (5), and distilling stream (5) to produce a bottoms stream containing 3-pentenonitrile and an overhead stream containing 2-methyl-3-butenonitrile.

Abstract: Aminolytic degradation of cross-linked polymer derived from 4-20C diisocyanates having urea, isocyanurate and optionally urethane and/or isocyanate structural units comprises reaction of polymer with aliphatic 8-30C mono- or diamines at 150-450 deg C whereby the reaction is carried out until the polymer has up to 20% of the initial isocyanurate, allophanate or urethane structural units. A process for the aminolytic degradation of cross-linked polymer (P), derived from 4-20C diisocyanates and optionally 1-20C aliphatic alcohols, having urea, isocyanaurate and optionally urethane and/or isocyanate structural units comprises reaction of polymer (P) with aliphatic 8-30C mono- or diamines (A) at 150-450 deg C whereby the reaction is carried out until the polymer is converted to reaction products having upto 20% of the initial isocyanurate, allophanate or urethane structural units.

Abstract: PCT No. PCT/EP98/03714 Sec. 371 Date Dec. 8, 1999 Sec. 102(e) Date Dec. 8, 1999 PCT Filed Jun. 18, 1998 PCT Pub. No. WO98/57886 PCT Pub. Date Dec. 23, 1998A very pure aqueous solution of free hydroxylamine is prepared by a process in which the dilute, aqueous hydroxylamine solution is concentrated in a column by removing hydroxylamine-containing vapors via a side take-off in the bottom of the column, and very pure hydroxylamine is obtained by condensing the vapors. The novel process can be carried out simply, in a gentle manner and on a large scale and gives electronic grade hydroxylamine.
