| titleOfInvention | Process for the preparation of phosphonous acids esters |
| abstract | a) elementaren gelben Phosphor mit Alkylhalogeniden in Gegenwart von Alkali- und/odernErdalkalihydroxiden zu einem Gemisch, welches als Hauptbestandteile die Alkali- und/odernErdalkalisalze der Alkylphosphonigen, Phosphorigen und HypophosphorigennSäure enthält, umsetzt b) aus dem nach a) erhaltenen Gemisch die Alkylphosphonige Säure entfernt c) die Alkylphosphonige Säure verestert. The present invention relates to a process for the preparation of phosphonous esters, characterized in that a) elemental yellow phosphorus with alkyl halides in the presence of alkali and / or alkaline earth metal hydroxides to form a mixture which contains the main constituents of the alkali metal and / or alkaline earth metal salts of alkylphosphonous, phosphorous and hypophosphorous acid b) the alkylphosphonous acid is removed from the mixture obtained according to a) c) esterifying the alkylphosphonous acid. n n n The invention also relates to the use of those produced by this processnPhosphonous esters. |
