Organotin compounds
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. 12 There are many kinds of organotin compounds, the general formula of which is RnSnX (R is the group, n is the number, Sn is the chemical symbol of tin), such as: tetraalkyltin compound (R4Sn), trialkyltin compound (R3SnX) , Dialkyltin compound (R2SnX2) and monoalkyltin compound (RSnX3), R is an alkyl group in the above general formula, which can be an alkyl group or an aryl group.
Organotin is a class of organic compounds widely used in industry and agriculture, including three organotin substances: organotin salts, organotin oxides and organotinanes. These organotin substances are chemically active and easily decompose, releasing toxic gases and soluble harmful substances.
Long-term exposure to organotin substances may produce toxic effects and cause harm to human health Influence. The main manifestations are poisoning symptoms, such as headache, nausea, vomiting, abdominal pain, insomnia and so on. Long-term exposure to organotin substances may cause damage to the immune system, nervous system, and cardiovascular system.
Therefore, when using organic tin substances, contact should be avoided as much as possible, And operate in strict accordance with the safety operating procedures to reduce the harm to human health.
Organotin compounds will decompose rapidly in the natural environment. After entering the organism, it is easily absorbed by the small intestine or skin, especially the three-substitution form is most easily absorbed and distributed in the liver, kidney and brain. The liver-based microsomal drug-metabolizing enzyme system dealkylates and dearylates very quickly.
Organotin compounds are organometallic compounds containing tin and carbon atoms. They are used in a variety of applications including as stabilizers in polyvinyl chloride (PVC) plastics, biocides and catalysts.
Organotin compounds can be divided into two categories: alkyltin compounds and aryltin compounds. Alkyltin compounds are those compounds containing carbon-tin bonds and alkyl groups while aryl tin compounds are those compounds containing carbon-tin bonds and aryl groups.
Alkyl tin compounds are commonly used as stabilizers in PVC plastics. They work by preventing PVC from breaking down when exposed to heat and light. Alkyltin compounds are also used as biocides, meaning they kill or prevent the growth of microorganisms. They are used in a variety of applications including paints and coatings, wood preservatives and marine antifoulings.
Aryltin compounds are often used as catalysts. They are used in a variety of applications including the production of polyurethanes, silicones and pharmaceuticals.
Organotin compounds can be toxic to humans and other animals. They can lead to a variety of health problems, including cancer, reproductive problems, and neurological problems. Organotin compounds also pollute the environment. They can enter the environment through industrial discharges, spills and agricultural runoff. Organotin compounds can accumulate in the food chain and are harmful to fish and other aquatic organisms.
In recent years, the use of organotin compounds has been regulated due to concerns about their toxicity and environmental impact. Some organotin compounds have been banned or restricted in use, while others are now used in lower concentrations.
