Organotin liquid refers to metal organic compounds containing Sn-C bonds, which are widely used as polyvinyl chloride stabilizers, antifouling coatings, insecticides, fungicides and Stabilizer for synthetic polyurethane and silicone etc. Organotin solution refers to a solution containing an organotin compound, usually a solution in which an organotin reagent is dissolved in an organic solvent. Because organotin compounds have certain toxicity and environmental pollution, when using organotin liquid, it is necessary to strictly control the usage amount and working conditions to avoid harm to human body and environment.
There are many types of organotin liquids, commonly used organotin reagents include methyltributyltin, di(tripropylsilyl)dimethyldiphenyltin, Four (tert-butyl) tin and so on. They are widely used in organic synthesis, such as Sonogashira coupling reaction, Stille coupling reaction, Negishi coupling reaction and other reactions often need to use organotin liquid.
When using organic tin liquid, you need to pay attention to the following points:
1. Choose a suitable organic solvent: Usually, organotin reagents are dissolved in organic solvents. Selecting a suitable organic solvent can ensure the reaction effect and the dispersion of organotin reagents sex.
2. Strictly abide by the operating procedures: organotin liquid is harmful to the human body and the environment, so it is necessary to follow the operating procedures when using it, and do a good job in safety protection and waste disposal .
3. Control the amount of usage and working conditions: Excessive usage of organic tin solution or improper working conditions will cause unnecessary waste and pollution, so it needs to be accurate according to actual needs Control usage and operating conditions.
In short, safety and environmental protection issues need to be paid attention to when using organotin solution. The basic principle of using organotin solution is to protect the safety of human body and environment.
