Properties and stability

1. Soluble in benzene, methylene chloride, carbon tetrachloride, ethyl acetate, acetone, slightly soluble in ethanol and gasoline, insoluble in water. It can gradually decompose when exposed to heat for a long time.
2. This product has low toxicity.
3. It can gradually decompose when exposed to heat for a long time.

Storage method

Store in a cool, dry and ventilated place, protected from moisture, fire and sun. Storage period is 6 months. It may clump easily during long-term storage, but it does not affect use.

Synthesis method

It is obtained by the reaction of accelerator M (2-thiol benzothiazole) and cyclohexylamine. Mix accelerator M and cyclohexylamine aqueous solution, add sodium hypochlorite dropwise under stirring to oxidize to obtain a crude product, separate the solid material, wash it with water until neutral, and dry it below 75°C to obtain the finished product.
