Usage

General Description

Methyldithiocarbamic acid, also known as Bedocide, is a chemical compound with the formula CH3NCS2OH. It is commonly used as a pesticide and microbiocide in agricultural and industrial applications for controlling a wide range of pests and microorganisms. Methyldithiocarbamic acid is a strong chelating agent and its complexes are used in water treatment and as additives for rubber vulcanization. It is also used in the synthesis of other chemicals such as dithiocarbamate-based fungicides. However, it is important to handle methyldithiocarbamic acid with caution as it is a toxic and corrosive substance that can cause skin and eye irritation, and prolonged exposure may have harmful effects on human health and the environment.

Method for synthesizing metham in one step

The invention discloses a method for synthesizing a soil fumigant metham in one step. The method comprises the following steps: stirring and mixing water, a monomethylamine aqueous solution and a sodium hydroxide aqueous solution, dropwise adding carbon disulfide, continuously stirring and reacting to obtain a finished product of metham with the appearance of yellow to red brown, wherein the finished product is used for treating soil fumigation and disinfection and killing root-knot nematodes, harmful bacteria and soil insects and removing weeds. The whole synthesis method has the advantages of high production efficiency, high product content, high operation safety, good storage stability and environmental friendliness.

Dazomet preparation process

The invention discloses a dazomet preparation process. The process comprises the following steps: of the first step reaction: enabling methylamine to react with carbon disulfide, adding an appropriate amount of extracting agent, separating to obtain an intermediate N-methylaminodithioformate; the second step reaction: enabling the intermediate N-methylaminodithioformate to react with formaldehyde in a reaction system added with an appropriate amount of sulfate and surfactant to obtain the dazomet. By use of the scheme disclosed by the invention, the extracting agent is added after the first step reaction is finished; the product carbon disulfide is further removed, thereby avoiding the influence on the product crystal structure, packing density and production security by residual carbon disulfide.
