(01. 260-461) This invention relates to novel organic phosbeing attached to other tom or rad alsfand phite compounds, particularly phosphite esters does not include'the unsaturated oleflns.

In order to produce di-substituted monohydroalkyl ethers of alkylene glycol's, the same molecular proportions of phosthe alkyl ether are used so as to replace the three chlorine atoms of the phosphorus trichloride and form the corresponding normal phosphite, but in this case two mols of the'HCl sequestering reagent are used so that one mol oi HClis lei'tto react with the normal phosphite to split off one glycol alkyl the molecule, forming the di-substituted monopresence of at least three mols ether group from whichboils below about 212 the standpoint of completeness of 1 hydrogen phosphite and the corresponding chlo- I ether, in. accordance with the equation set. forth above. These can then be j separated by distillation to recover the acid ester.
In order to form the mono-substituted dihydrogen phosphite, the corresponding ,di-substltuted monohydrogen phosphite isreacted with one mol of HCl organic solvent and in the absence of an HCl sequestering reagent, thereby producing the monosubstituted dihydrogen ester and the corresponding chloride 01' the alkyl ether; according to the equation These can then be separated by distillation.
The above reactions are carried out generally ior example as from wise to the cooled mixture, of alkyl ether, 'solve'nt and H01 sequestering reagent. After completion of. the addition of the phosphorus trichloride, the mixture is preferably r time at the boiling point of the solvent used I I ,It is then cooled, may be washed With'water to re- .55 in thepresence of a suitable.

vacuum to recover the desired ester as a distillate.
Any low boiling aliphatic or aromatic hydrocarbon or chlorinated hydrocarbon solvent can be employed, although preferably one is selected F. Examples .01 hexane, heptane. and the like. If
suitable solvents are pentane, carbon tetrachloride, benzene,
dry benzene, while the temperatur v A e was maintained between 23-50 F.
