Appearance: Off-White
Powder Origin: CHINA
Preparation method: The key to the synthesis of methomyl is the synthesis of the intermediate methomyl oxime. Depending on the selected synthesis route, the yield and cost of methomyl oxime will increase. Generally there are five methods for the synthesis of methomyl oxime: thioacetaldehyde oxime method; acetaldehyde method; methyl ethyl ketone method; nitroacetaldehyde method; acetaldehyde method. The operation steps of the acetaldehyde method are equal to the reaction of acetaldehyde and microsamine under the action of an acid binding agent. The generated acetaldehyde oxime reacts with chlorine at a certain temperature. After a certain period of time, sodium methylmercaptide is added dropwise and adjusted with alkali. PH value, cooling, suction filtration and drying, the white crystals obtained are methomyl oxime.

Glufosinate-P 90%
L-Glufosinate 90% (Glufosinate-P) is by far the only natural sense herbicide containing the C-P-C structure, which is about 4 times the grass glyphosate, which is twice the proclastation of the grass and two times the somatoscope (DL-type). Glufosinate-P adsorbs the activity of glutamine synthetase causing the cytotoxic ammonium ions to accumulate in the plant, destroying its photosynthesis.
