China Professional Supplier -N-Hydroxy-2- Ethanimine Methylsulfanyl-Acetaldehyde Oxime

The properties of (10533-67-2) : The pure methomoxime is white or pale yellow solid, melting point 94 ~ 97ºC[93 ~ 95ºC(Z type), 47 ~ 50ºC(E type)], and does not decompose within 24 hours at 74ºC.It decomposes 93% at 105ºC for 48 hours.Methomoxime solution does not decompose within 12h at pH=7;When pH=2, it decomposed to 12% at 24h and 18% at 72h (both at 25ºC). It was difficult to dissolve in water and soluble in organic solvents.
Methylthio acetaldoxime

Production method:

Preparation method of Methylthio acetaldoxime (10533-67-2) : The key to the synthesis of Methomyl is the synthesis of the intermediate methomyl oxime.The selection of synthetic route is different, metaxime yield and cost are far apart.metaoxime synthesis generally has the following five methods: sulphyl acetaldoxime method;Acetonitrile method;Methyl ethyl ketone method;Nitroethane method;Acetaldehyde method.metaoxime is mainly produced by acetaldehyde method in China.The operation procedure of acetaldehyde method is to react acetaldehyde with hydroxylamine hydrochloride under the action of acid binding agent, and the acetaldehyde oxime generated is then reacted with chlorine gas at a certain temperature. After a certain time, sodium methiol is dropped, pH value is adjusted by alkali, and the white crystal obtained is metaoxime.
