Sulfur is flammable and explosive, and it is easy to explode or burn when mixed with air. It needs to be kept closed and protected from light. Although sulfur powder is a low-toxic hazardous chemical from a toxicological point of view, its steam and sulfur dioxide produced after sulfur incineration are highly toxic to humans. It reacts violently with halogens, metal powders, etc. Sulfur is a poor conductor, and it will generate static charge during storage and transportation, which can also cause sulfur dust to catch fire. Dusts can form explosive mixtures when mixed with air or oxidizing agents.
A new process for improving the hydrophilicity of sulfur powder, a pesticide intermediate. In this process, sodium butyl sulfonate, sodium p-methoxy fatty acid amine benzene sulfonate or general washing powder are used as surfactants, and the pulverization of sulfuric acid powder is added. In the grinding process, the surface tension of the molecular clusters of the generated sulfur powder is significantly reduced after entering the water, and the hydrophilicity is greatly improved, which provides favorable conditions for the convenience of pesticide processing in the future to increase efficiency and reduce costs.
