权利人:ARKEMA FRANCE
摘要:The invention relates to a process for the synthesis of a monounsaturated nitrile-ester (acid) by cross metathesis starting from an unsaturated compound I comprising at least one trivalent nitrile, acid or ester functional group, characterized in that it comprises a stage in which two types of cross metathesis are alternated consecutively:n a first type of cross metathesis cm1 with an acrylic compound II chosen from acrylonitrile, acrylic acid or an acrylic ester, one of the compounds I or II comprising a nitrile functional group and the other of these compounds II or I comprising an acid or ester functional group, and a second type of cross metathesis cm2 with a light C 2 to C 4 alkene compound III, preferably with ethylene. nn The invention also relates to a process for the synthesis of an α,ω-amino ester (acid) obtained by a process comprising a stage in which the two types of cross metathesis defined above are alternated consecutively, followed by a hydrogenation stage.

摘要:The present invention relates to a novel method of synthesis of copper (I) 5-nitrotetrazolate. Particularly, for the synthesis of the copper (I) 5-nitrotetrazolate, the present invention uses a suitable salt of 5-aminotetrazole, preferably the sulfate or the nitrate salt as the starting compound. The selection of the said starting chemical not only eliminates any safety issue arising during Sandmeyer reaction conditions to affect the functional group conversion but also greatly improves the ease of executing the synthetic protocol, rendering the process safe to be adopted for commercial manufacture of the copper (I) 5-nitrotetrazolate compound.

标 题:Process for the synthesis of highly pure cationic surfactant products

摘要:The present invention is related to synthesis of highly pure cationic surfactant products by eliminating or reducing impurities generation that has beset prior art. This is achieved through the N-acylation of ester of amino acid and its inorganic salts or its organic salts (e.g. amino acid or hydrochloride of amino acid or sulfate of amino acid or acetate of amino acid etc.) in non-hydrolytic or nearly non-hydrolytic reaction conditions involving mono or biphasic reaction system with fatty acid halide (C 4 to C 20 ), under moderate uniform basic condition yielding high purity N-acyl substituted amino acid ester, particularly ethyl lauroyl arginate. The present process achieves pH control through process strategy rather than the measurement and control steps. This ambient temperature process is stable through a range of temperature variation eliminating rigid low temperature control.
