Beschreibung
Zusammenfassung:	The invention provides a process for producing dialkylphosphinic salts of the formula (I), in which a and b may be the same or different and are each independently 1 to 9, and where the carbon chains may be linear, branched or cyclic, and M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base and m is 1 to 4, characterized in that the process comprises: feeding a substream of renewable raw materials and/or recycled raw materials into a main stream of conventional raw materials originated from petroleum;converting said renewable raw material and/or recycled raw materials to ethylene together with said conventional raw materials; reacting the resultant ethylene stream with derivatives of hypophosphorous acid to give a derivative of the dialkylphosphinic acid; and reacting said derivative of the dialkylphosphinic acid with a metal salt to give dialkylphosphinic salts of the formula (I), wherein the renewable raw materials are tall oil, tung oil, wood tar, creosote, or vegetable oils such as palm oil, soya oil, rapeseed oil, sunflower oil, palm kernel oil, cottonseed oil, peanut oil, maize kernel oil, coconut oil, olive oil, sesame oil, linseed oil and/or safflower oil, wherein said recycled raw materials are selected from food wastes, residues or wastes from food production, papermaking or pulp processing, and any other materials of recycled origin, and the ratio of said mainstream of conventional raw material to said substream of renewable raw materials and/or recycled raw materials is 109:1 to 1:106. L'invention concerne un procédé de production de sels d'acides dialkylphosphiniques de formule (I), dans laquelle a et b peuvent être identiques ou différents et représentent chacun indépendamment 1 à 9, et où les chaînes carbonées peuvent être linéaires, ramifiées ou cycliques, et M représente Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K et/ou une base azotée protonée et m représente 1 à 4, caractérisé en ce que le procédé consiste à acheminer un courant partiel de matières premières renouvelables et/ou de matières premières recyclées dans un courant principal de matières premières classiques provenant du pétrole ; à convertir ladite matière première renouvelable et/ou desdites matières premières recyclées en éthylène conjointement auxdites matières premières classiques ; à faire réagir le courant d'éthylène obtenu avec des dérivés de l'acide hypophosphoreux pour donner un dérivé de l'acide
