Organotin compounds are metal organic compounds formed by the direct combination of tin and carbon. Agents (such as dimethyltin, dioctyltin, tetraphenyltin), agricultural insecticides, fungicides (such as dibutyltin, tributyltin, triphenyltin) and coatings and antifungal agents for daily necessities, etc. 1. Organotins are mainly used as fungicides and plastic stabilizers2. Because of the extensive use of organotins, many reports of related poisoning cases can be seen, and because of the strong neurotoxicity of organotins, poisoners are easily mistaken for mental illness and cases of delayed treatment also occur frequently. Organotin compounds have some important chemical and application roles, the following are some typical examples:

1. Catalysts for organic synthesis: Some organotin compounds have important catalytic functions, such as catalysts for the synthesis of acrylonitrile in industrial production, or catalysts for organic chemical reactions in organic synthesis, such as tin Acetylacetone, tin alkylate and tributyltin, etc.

2. Metalorganic chemical reagents: Many organotin compounds have Properties of chemical reagents, such as organotin oxides and organotin halides, etc.

3. Antifungal agents and preservatives: Some have antibacterial and antibacterial properties Organotin compounds with fungal action are widely used in wood preservation, paint and plastic material protection, such as hexamethylbis(bisphenoxy)tin, hexa(tert-butyl)tin and hexa(trimethyloxy)tin wait.

4. Heat stabilizers and light stabilizers: Some organic tin compounds act as thermal Stabilizers and light stabilizers are widely added to materials made of thermoplastics, paints, rubber, etc. to improve the heat resistance and light resistance of these materials.

Although organotin compounds are widely used, there are also environmental and health concerns Potential problems, so its use and emissions need to be strictly controlled and managed.
