| Abstract: | Dimethyl phosphite is a main intermediate of synthesis glyphosate. Its residue mainly is used in recycling the phosphorous acid. This article introduced two production methods to get the phosphorous acid with the hydrolysis and the acidolysis, which have the high return ratio and good product quality. Meanwhile, three waste discharge is reduced. |
