China Methomyl Oxime Methylthio Acetaldoxime CAS 10533-67-2 C3h7nos Used for Synthesis of Methomyl

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.

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.

Company Information;
Hongze Chemical's existing main products: methylthioacetaldoxime, methomyl, sodium methyl mercaptan and other pesticides that do not contain hazardous chemicals. Among them, the annual output of methomyl oxime developed by our company is 18,000 tons, and does not contain dangerous chemicals, so it benefits the majority of farmers!
Methylthioacetaldoxime is abbreviated as methomyl oxime, which is an economically valuable intermediate that can be used to manufacture carbamate insecticides such as methomyl, thiodimethocarb and melanolin.
