摘要： Disclosed is a method for the simultaneous preparation of dicarboxylic acids and diamines from (a) polymers based on polyamides made by reacting dicarboxylic acids or derivatives thereof with diamines or (b) compounds containing essentially such polymers, by decomposing these polymers into their constituent monomers by treating the polymers or compounds with a base in an alcoholic solution and subsequently converting electrochemically the dicarboxylic-acid salts thus produced into the corresponding dicarboxylic acids and bases.

摘要： The invention relates to a method for producing 2-{1-[2-(4-chlorophenoxy)-propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyrane-3-yl)-cyclohex-2-enone lithium salt by reacting the corresponding acid 2-{1-[2-(4-chlorophenoxy)-propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyrane-3-yl)-cyclohex-2-enone with lithium hydroxide, and for extracting the lithium salt. It is advantageous to use a solvent mixture containing methanol and at least one aromatic hydrocarbon, and to remove part of the solvent before extraction. It is especially preferable to dissolve the acid in an aromatic hydrocarbon, preferably toluol, and to use a methanolic lithium hydroxide solution. The product obtained efficiently according to the inventive method also has considerable advantages in terms of formulation techniques.

摘要： A process is disclosed for producing isomer mixtures from O-phenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R1)-O-Ar and Ib: H¿2?N-O-CH(R?1)-CH¿2-O-Ar (wherein R1 represents alkyl, Ar where appropriate a substituted phenyl) and the corresponding salt mixtures. This process involves the following steps: (a) an isomer mixture of O-(2-hydroxyethyl)-oximes (IIa) and (IIb) (in which R2 is an alkyl and R3 is an alkyl or alkoxy, or R?2 and R3¿ together with the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO¿2-R?4 (wherein R4 represents an organic group and Hal is a halogen) in the presence of a base to form the corresponding sulphonate mixture of (IVa) and (IVb); (b) this sulphonate mixture is reacted in the presence of a base with a phenol of formula (V): HO-Ar to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) and (VIb); (c) the mixture is hydrolysed in the presence of an acid and, if required, (d) the O-phenoxyalkylhydroxyl amines (Ia) and (Ib) are released from the resulting salts using a mineral base. The O-phenoxyalkylhydroxyl amines (Ia/Ib) and their precursors (VIa/VIb) are important intermediate products for plant protective agents and drugs.
