Title: Process for the preparation of a trialkyl phosphite
IPC: C07F9/142
Filed: 1962-01-26
Abstract: A trialkyl phosphite is obtained by reacting an alkanol with phosphorus trichloride or tribromide in the presence of a tertiary amine having the formula R3N wherein each R is an allyl group or a C5-C10 alkyl group.  The trialkyl phosphite is readily recovered by distillation of the reaction mixture.  The alkanol used is preferably one having 1 to 4 carbon atoms and is preferably methanol.  Specified tertiary amines are triamyl-, triisoamyl-, triisooctyl-, trinonyl-, diamyl isoamyl-, diamyl octyl-, and triallyl-amines, triallylamine being preferred.  At least 3 moles of the alkanol and of the tertiary amine should generally be used per mole of phosphorus trihalide and preferably a slight excess of the alkanol, e.g. from 0.5 to 5% over the stoichiometric amount is used.  Suitable reaction temperatures vary from -30 DEG C. to 200 DEG C. according to the reactants and tertiary amine employed.  The reaction can be carried out under reduced pressure and is preferably effected in the liquid phase.  It can also be carried out in the vapour phase at a temperature at which the amine hydrohalide is liquid, the hydrohalide being condensed from the vapour phase as fast as it is formed.  A solvent may be present but it is preferred to avoid the use of a solvent and to carry out the reaction under substantially anhydrous conditions. The reaction is best conducted by adding the phosphorus trihalide dissolved in part of the amine to the alkanol dissolved in the remainder of the amine.  The bottoms obtained on distillation of the reaction mixture (preferably under reduced pressure) to recover the trialkyl phosphite contain the amine hydrohalide and small amounts of dialkyl phosphite and may be treated with aqueous alkali to regenerate the amine and remove the water-soluble dialkyl phosphite and the regenerated amine may be used again in the process.  Examples are given for the preparation of trimethyl phosphite.
