Trichloro(2,3-dimethyl-2-butyl)silaneTrichloro(1,1,2-trimethylpropyl)silane - Introduction
Thexyltrichlorosilane (also known as TMSPCl) is an organosilicon compound. Its chemical formula is C4H13Cl3Si. The following is a description of its nature, use, formulation and safety information:
Nature:
1. Appearance: TMSPCl is a colorless to pale yellow liquid.
2. Melting point: Its melting point is usually between -2 and 0 degrees Celsius.
3. Boiling point: The boiling point of TMSPCl is about 157 degrees Celsius.
4. Solubility: It is soluble in some organic solvents, such as alkanes, aromatics, etc.
5. Flammability: TMSPCl is a flammable liquid, its vapor and air form a flammable mixture.
Use:
TMSPCl has many uses in chemistry, including:
1. As a silicon protecting group in organic synthesis: TMSPCl can react with active hydrogen atoms to form 1,1, 2-trimethylpropenyl groups, thereby protecting active groups in other reactions.
2. As a catalyst: TMSPCl can form a catalyst with metal complexes for organic synthesis reactions.
3. As a surfactant: The hydrophobic and hydrophobic silicon groups of TMSPCl make it useful as a surfactant and interfacial modifier.
Method:
The preparation of TMSPCl is generally carried out by the following reaction:
(CH3)3CSiH Cl2 → (CH3)3CSiHCl2 → TMSPCl HCl
Safety Information:
1. TMSPCl is an organic compound, and care should be taken to prevent it from contacting the skin, eyes and mouth. Wear protective gloves, goggles and mask for operation.
2. When operating organic solvents, Good Laboratory Practices should be followed to ensure good ventilation and avoid the accumulation of vapors.
3. TMSPCl is a flammable liquid and should be kept away from open flames and high temperature sources. Store in a cool, dry place, sealed, away from heat.
4. The toxicity data related to TMSPCl is relatively limited, so general guidelines for safe handling and handling of chemicals should be followed.
