General Description

1,3-Divinyl-1,3-dimethyl-1,3-dichlorodisiloxane is a chemical compound with the molecular formula C6H12Cl2O2Si2. It is a colorless liquid with a strong odor, and it is mainly used as a monomer in the production of silicone polymers. The presence of vinyl and methyl groups in the molecule makes it suitable for various polymerization reactions, leading to the formation of silicone elastomers, resins, and other silicone-based materials. Additionally, this compound is used in the manufacturing of adhesives, sealants, and coatings due to its excellent adhesion properties and resistance to heat, chemicals, and weathering. However, it should be handled with care as it is a hazardous chemical with potential health and environmental risks.

METHOD OF MAKING HALOSILOXANE

A method of producing a halosiloxane, the method comprising: combining water, a halosilane, and first solvent, where the first solvent has a water solubility of > 1.5 grams in 100 ml of solvent, to form a reaction mixture having a temperature above the melting point temperature of the solvent, partially hydrolyzing and condensing the halosilane to form a reaction product mixture comprising the halosiloxane, the solvent, a hydrogen halide and unreacted halosilane, and, optionally, adding a second solvent with a boiling point the boiling point of the halosloxane to the reaction mixture or the reaction product mixture.
