Abstract: The invention relates to a method for the production of propylene oxide, whereby (i) propylene is reacted with hydrogen peroxide in the presence of methanol to form propylene oxide, resulting in a mixture (Gi), comprising propylene oxide, methanol, water and unreacted hydrogen peroxide, (ii) from mixture (Gi) a mixture (Gii), comprising methanol, water and hydrogen peroxide is separated off, yielding a mixture (Ga), comprising propylene oxide. Water is separated off from mixture (Gii) to give a mixture (Giii), comprising methanol and methyl formate.

Abstract: 6-Aminocapronitrile (6-ACN) is separated from its mixtures with adiponitrile and hexamethylenediamine (HMDA) by a 3-step distillative process. Distillative separation of 6-aminocapronitrile (6-ACN) from its mixtures with adiponitrile and hexamethylenediamine (HMDA) comprises: (a) separating out HMDA to give a mixture (M-I) of HMDA content below 1 wt.%; (b) partly or completely separating out 6-ACN from (M-I) to give a mixture (M-II) containing less than 1 wt.% of materials which are higher boiling than 6-ACN under distillation conditions and which cannot be formed by heat dimerization of 6-ACN; and (c) partly or completely separating out any existing HMDA from (M-II) to give a mixture (M-III) with a HMDA content higher than (M-II) and a mixture (M-IV) with a HMDA content lower than (M-II).

Abstract: The invention relates to a method for producing cyclic lactams of formula (II) by reacting a compound (I) of formula (I) with water in the presence of an organic, liquid dilution agent in the liquid phase. In formula (II), n and m respectively can have the values 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 and the sum of n + m is at least 3, preferably at least 4 and R and R represent C1-C6 alkyl, C5-C7 cycloalkyl or C6-C12 aryl groups. In formula (I), R , R , m and n are defined as above and R represents nitrile, carboxylic acid amide and carboxylic acid groups. The inventive method is characterized in that a) compound (I) is reacted with water in the liquid phase in the presence of an organic, liquid dilution agent (III) to form a mixture (IV) containing a lactam (II) and said mixture (IV) is subjected to an aqueous treatment to obtain a two-phase system.

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: Hydrocyanation of olefinically unsaturated nitriles in the presence of a zero-valent nickel catalyst comprises performing the reaction in the presence of a hydrocarbon that forms a catalyst-rich phase and a catalyst-lean phase. An independent claim is also included for separating adiponitrile from a mixture comprising adiponitrile and a zero-valent nickel catalyst by means of a hydrocarbon with a b. pt. of 90-140[deg]C.

Abstract: A process for removing high boilers from crude caprolactam which comprises high boilers, caprolactam and in some cases low boilers, and which has been obtained by a) reacting 6-aminocapronitrile with water to give a reaction mixture b) removing ammonia and unconverted water from the reaction mixture to obtain crude caprolactam, which comprises c) feeding the crude caprolactam to a distillation apparatus to obtain a first substream via the top as a product and a second substream via the bottom, by setting the pressure in the distillation in such a way that the bottom temperature does not go below 170° C., and adjusting the second substream in such a way that the caprolactam content of the second substream is not less than 10% by weight, based on the entire second substream.

Abstract: A method for the production of 6C dicarboxylic acids (I) from acrylic acid involves reacting diesters of (I) with acrylic acid to give (I) and acrylate esters, separating (I) from the reaction mixture, dimerizing the acrylate esters to diesters of n-butene dicarboxylic acid and converting these diesters into (I). A method for the production of dicarboxylic acids of formula HOOC-(n-C4Hx)-COOH (I) from acrylic acid involves: (a) reaction of diesters of formula R1OOC-(n-C4Hx)-COOR2 (II) with acrylic acid to give (I) and a mixture of acrylate esters of formula C2H3COOR1 and C2H3COOR2; (b) separation of (I) from the reaction mixture; (c) dimerization of the acrylate esters to give diesters of n-butene dicarboxylic acid; and (d) cleavage of these diesters to give (I). x = 6 or 8; and R1, R2 = 1-4C alkyl, aryl or heteroaryl.
