Usage

General Description

DICHLOROMETHYL-N-PROPYLSILANE is a chemical compound that is a clear, colorless liquid with a pungent odor. It is commonly used as a crosslinking agent for various polymers and as a coupling agent in the synthesis of organic and inorganic materials. This chemical is highly reactive and can undergo hydrolysis in the presence of water, generating toxic and flammable hydrogen chloride gas. It is considered to be hazardous if ingested, inhaled, or in contact with skin and eyes, and should be handled with extreme caution. Additionally, DICHLOROMETHYL-N-PROPYLSILANE is incompatible with strong oxidizing agents and bases, and should be stored and handled in a well-ventilated area with proper personal protective equipment.

Production method of chloropropylmethyldichlorosilane

The invention relates to a production method of chloropropylmethyldichlorosilane and belongs to the field of organic chemistry. The production method comprises the following steps: firstly, enabling chloroplatinic acid to react with isopropanol, acetic acid, phenyl silicone oil and the like; secondly, neutralizing by adopting sodium acetate, enabling part of the isopropanol complexed with platinum to be completely substituted under the alkaline conditions, thereby enabling a ligand of a catalyst to be directly substituted with the acetic acid and the phenyl silicone oil; after substitution, by taking tributylamine as a promoter, avoiding the inactivation of the catalyst in the addition reaction; during synthesis, reacting by adopting mixed feeding, adding at low temperature, and raising the temperature for continuous reaction after most reaction is finished; after the reaction is finished, completely distilling low boiling point products at normal pressure, and then distilling foreshot under vacuum conditions; after the foreshot are distilled, obtaining a chloropropylmethyldichlorosilane product with the content of 99.5 percent or above. The synthesized product disclosed by the invention has the advantages of high yield, low capacity, fewer byproducts, low requirement on equipment, and the like; in addition, the production method is relatively-simple in industrial production.

Continuous Preparation of Organosilanes

The invention relates to a process for the continuous preparation of organosilanes in a reactive distillation column, wherein a homogenous hydrosilylation catalyst is introduced into the column.

The hydrosilylation of propylene

The reactions of separate and competitive hydrosilylation of propylene with HSiCl3, MeSiHCl2, Me2SiHCl, and MePh2SiH in the presence of the Speier catalyst (SC) with different additives and a catalyst obtained from SC and propylene were studied. A mutual influence of the hydrosilanes in the competitive reactions was found. The influence of various additives to SC on the process was considered.
