Production of alkyl phosphites |
| abstract |
This invention relates to an improved process for producing diesters of phosphorous acid. The process comprises (a) reacting phosphorous acid with monohydric alcohol in a petroleum distillate solvent while maintaining a reaction mass temperature within the range of from about 130 DEG to about 138 DEG C., and (b) refluxing the reaction mass during the reaction, wherein the phosphorous acid contains about 20 up to about 35 wt. % water, the molar ratio of alcohol to phosphorous acid used is within the range of from about 2.0:1 to about 4.0:1, and water is removed from the reaction mass essentially as it is formed during steps (b) and (c). |
