Stabile wäßrige Lösungen von Triphenyldodecy1- phosphoniumpentachlnrphe.nolat kann man auch erhalten, wenn man die LTlnsetzung von Allali- pentachlorphenola.t mit Triphenyldodecylphospho- niumhalogenid oder von Pentachlorphennldodecy1- äther mit Triphenylphosphin in Gegenwart eines der vorstehend erwähnten Lösungsvermittler vornimmt. Die Herstellung von Triphenyldodecylphosphoniumpentachlorphenolat in Gegenwart von Lösungsmitteln ist Gegenstand des Patents 920 726.

The preparation of triphenyldodecylphosphonium pentachlorophenolate in the presence of solvents is the subject of patent 920 726. Example 10 g of triphenyldodecylphosphonium pentachlorophe.nolate are mixed with 20 g of 1% diethyldodecylamine chloride and 709 % of water. After thorough stirring, a clear solution is obtained in a short time without heating, which can be further diluted with water in any ratio.
