Paragraph 0022-0034, (2019/02/04)
The invention discloses a preparation method of a glufosinate intermediate. Under the existence of heterobimetallic molecular sieve type catalyst CuZr/ZSM-5, acrylic aldehyde is dropwise added into amixed solution of methyl diethyl phosphite and absolute ethyl alcohol for reaction; after the reaction is completed, vacuum concentration is performed; the glufosinate intermediate of 3-(methyl ethyloxy) phosphonopropylal diethanol is obtained. The method has the advantages that the process is simple; the operation is easy; the reaction conditions are mild; the yield is high; the atom economy is high; the catalyst can be easily recovered and utilized; the industrial prospects are good.
