Usage

General Description

1,1,3,3,5,5-hexamethyl-1,5-divinyltrisiloxane, also known as HMDS or hexamethyldisiloxane, is a colorless and odorless liquid used in various industrial applications. It is a type of organosilicon compound that contains silicon, carbon, and oxygen atoms in its chemical structure. HMDS is commonly utilized as a reagent in the synthesis of silicon-based materials and as a solvent in chemical reactions. It is also used as a surface treatment agent in the production of electronic devices, as well as a release agent in the manufacture of rubber and plastics. Additionally, HMDS is utilized in the production of silicones, adhesives, and sealants. Due to its low surface tension and ability to form thin, uniform coatings, it is also used as a lubricant and water repellent in various applications.

PREPARATION METHOD OF VINYL-TERMINATED SILOXANE

The invention relates to a preparation method of vinyl-terminated siloxane. R2R3Si(OR4)2, R12(CH2═CH)SiOSi(CH═CH2)R12, an organic acid and a catalyst are added into a reaction bottle according to the molar ratio of 1:1-1.5:1-2.5:0.005-0.01, wherein R1 is alkyl, R2 and R3 are alkyl, aryl or substituted alkyl, substituted aryl identically and differently, and R4 is alkyl, heating is performed to 50-80° C. while stirring, the stirring reaction is performed at the temperature for 5-30 min, then a dehydrating agent is added, and the reaction is continuously performed for 2-5 h at the temperature of 50-80° C.; and the temperature is reduced to room temperature after the end of reaction, and then dilution, washing with water to neutral, collection of an organic phase, drying, filtering, concentration, reduced pressure distillation and collection of a fraction at corresponding pressure and temperature are sequentially performed so as to obtain a vinyl-terminated siloxane compound product.
