Abstract: The invention relates to mixtures of propoxylated 4-toluidines containing two or more different di- or tri-propoxy lated or higher propoxylated p-toluidines in specific weight ratios, to methods for preparing them and to their use as polymerization accelerators or vulcanization accelerators or as hardener components in epoxy resins.

Abstract: According to the invention, N-butyryl-4-amino-3-methyl-methyl benzoate is obtained in a particularly advantageous manner by, initially, reacting o-toluidine with butyric acid chloride, by brominating the reaction product and by reacting the bromide obtained therefrom with carbon monoxide and methanol in the presence of a palladium catalyst. The invention also relates to the important novel chemical compound N-(4-bromine-2-methylphenyl)-butanamide.

Abstract: Acetophenones which are di- or polysubstituted by fluoroalkyl groups on the aromatic ring are prepared in a particularly advantageous manner from the corresponding fluoroalkylanilines and acetaldoxime by preparing a corresponding diazonium salt mixture from the fluoroalkylaniline, reacting this mixture with acetaldoxime in the presence of at least one copper and/or palladium compound, without adding buffer salts or a reducing agent, carrying out the reaction with acetaldoxime at 5 to 50° C. and in the presence of halide ions and at least one strong acid that is not a hydrohalic acid, and finally heating the mixture to a temperature in the range 70 to 160° C.
