Abstract
Neutral esters of phosphoric acid are manufactured by reacting phosphorous pentoxide or an organic metaphosphate or pyrophosphate with excess of an organic ether free from polar substituents, at a temperature of 65-180 DEG C. (preferably 140-180 DEG C.). The reaction may be carried out in the absence of a catalyst, but improved yields are obtained by the use of an esterification catalyst, e.g. iodine, ferric chloride, sulphuric acid, phosphoric acid or cobaltous acetate. When using phosphorus pentoxide, the molar ratio of ether thereto is preferably between 3 : 1 and 10 : 1. The alternative starting materials may be, for example, ethyl metaphosphate or tetraethylpyrophosphate, or the residue from a previous reaction using phosphorus pentoxide. The ether may be an alkyl ether (simple or mixed) or an aryl ether, e.g. diethyl, di-n-propyl or di-isobutyl ether, methyl ethyl ether (which yields a mixture of diethyl methyl and dimethyl ethyl phosphates), or diphenyl ether. Examples describe the preparation of triphenyl and triethyl phosphates. The products are useful as plasticizers, spinning lubricants, antistatic agents, catalysts or surface-active agents.
