Abstract:
The invention relates to a method for producing phosphoric acid triesters of formula (I). According to said method, phosphoric acid or a phosphoric acid derivative selected from orthophosphoric acid, tetraphosphoric decaoxide and polyphosphoric acid is reacted with alkoxylated alcohols of formulae (II) R1—(OA1)x-OH, (III) R2—(OA2)y-OH, and (IV) R3—(OA3)Z-OH, in the molar ratio phosphoric acid or phosphoric acid derivative to alkoxylated alcohol of 1:2.5 to 1:3.3, at between 200 and 240° C.
