The vast majority of organophosphorus pesticides produced in my country are pesticides, such as commonly used parathion, systemic phosphorus, malathion, dimethoate, trichlorfon and dichlorvos.

Organophosphorus pesticides refer to organic compound pesticides containing phosphorus elements. Mainly used to control plant diseases, insects and weeds.

Enzymes are biological catalysts, which are organic substances with catalytic ability produced by plants, animals and microorganisms (most proteins. But a small amount of RNA also has biocatalytic fun

Heterogeneous catalysts, also known as heterogeneous catalysts, are used in reactions of different phases, that is, in different states from the reactants they catalyze.

The reaction in which the catalyst and the reactants are in the same phase without the existence of a phase boundary is called homogeneous catalysis, and the catalyst that can play the role of homogen

The catalyst will lose its activity rapidly or slowly under the influence of various factors during use. The reasons for catalyst deactivation are complex.

The first catalyst production workshop in my country was the Catalyst Department of Yongli Mineral Plant, which was renamed Nanjing Chemical Industry Corporation Catalyst Factory in 1959.

Chemical bonding method. This method is now widely used in the manufacture of polymerization catalysts. Its purpose is to solidify the homogeneous catalyst.
