    Abstract: The present invention describes a process for the preparation of ethyldimethylamine and triethylamine with the following steps: (i) reaction of a mixture of diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of alkali metal dimethylamides, alkali metal diethylamides and alkali metal hydrides (ii) removal of the catalyst (iii) distillation separation of the resulting mixture in triethylamine and ethyldimethylamine and optionally diethylamine and dimethylamine (iv) optional return of the catalyst and of the starting amines to the reaction. The process according to the invention permits the coproduction of ethyldimethylamine and diethylamine in a simple process.

    Abstract: In the present invention there are disclosed impregnated salts containing at least one salt of one or several organic carboxylic acids in which 0.5 to 30 percent by weight of at least one organic carboxylic acid has been incorporated in relation to the carboxylic acid salt. A process for preparing such impregnated salts is characterized in that at least one carboxylic acid salt from carboxylic acid mixture is impregnated with at least one liquid carboxylic acid to concentration of 30 percent by weight, based on the carboxylic acid salt. The invention also relates to a process for preparing preservatives, which preparation process comprises mixing of a salt, impregnated according to the present invention, with one or several carrier substances and/or formulation auxiliary agents, the mixture is the agglomerated with or without addition of at least one binding agent. The invented impregnated salts or preservatives are used for treating foodstuffs and animal food, and for silage or for treating leather.
