摘要:
The present invention relates to a catalyst for cross-linking silicone rubber compositions. In particular, the present invention provides a composition for producing a silicone rubber composition, the composition comprising a catalyst which has at least two compounds that are different from each other and are selected independently from one another from metal salts of carboxylic acids. The present invention further provides a use of the catalyst according to the invention for cross-linking a silicone rubber composition, and a use of the composition according to the invention for producing a silicone rubber composition, in particular for use as a sealant, an adhesive or a coating agent.

The present invention relates to a catalyst for cross-linking silicone rubber compositions with a lactate-based cross-linking agent. In particular, the present invention provides a composition for producing a silicone rubber composition with a lactate-based cross-linking agent, the composition comprising a catalyst which has at least two compounds that are different from each other and are selected independently from one another from metal salts of carboxylic acids. The present invention further provides a method for producing such a composition and a use of the catalyst for cross-linking a silicone rubber composition, in particular for cross-linking a silicone rubber composition with a lactate-based cross-linking agent, and a use of the composition according to the invention for producing a silicone rubber composition, in particular for use as a sealant, an adhesive or a coating agent.

The invention relates to a method for producing dinitro-diaza-alkanes and intermediate products hereto from alkylamines and esters. According to the inventive method, a dialkylester of a dicarboxylic acid is converted with an alkylamine in an aqueous medium into the corresponding dialkyldiamide of the dicarboxylic acid. The obtained dialkyldiamide is nitrated using common nitrating agents to form the corresponding dialkyldinitroamide of the dicarboxylic acid. The obtained dialkyldinitroamide is converted with methylamine and/or ethylamine in an aqueous medium into the corresponding alkyl nitramine and into dimethylamide and/or diethyldiamide of the dicarboxylic acid. The alkyl nitramine is isolated out therefrom and is condensed in a conventional manner to form dinitro-diaza-alkanes.
