摘  要:
preparation of methidathion, which is started from hydrazine hydrate, reacting with trichloromethyl chloroformate, methyl sulfide and synthesis methods of methidathion, home and aboard, are being summarized in this article. We have developed a new technology for formaldehyde. Purityobtained in one time is around 96% - 98%: and the total yield is 42 %, calculated as hydrazine hydrate.
