dichloro-bis(trimethylsilyloxy)silane - Introduction

3,3-dichloro-1, 1,1,5,5, 5-hexamethyltrisilane, referred to as DCTS, chemical formula C6H18Cl2O2Si3, is an organic silicon compound.

The main properties of DCTS include:

1. Appearance: colorless transparent liquid.
2. Boiling Point: about 176-181 C.
3. Density: about 1.20 g/cm.
4. Solubility: Soluble in many organic solvents, such as alcohols, cycloalkanes and aromatic hydrocarbons.
5. Non-flammability: DCTS is not easy to burn under regular temperature and pressure.

The main uses of DCTS include:

1. Functional Coatings: DCTS can be used as a crosslinking agent or reactive solvent in coatings to provide surface hardening and abrasion resistance.
2. Electronic materials: DCTS can be used to prepare siloxane films, which have certain insulation properties and heat resistance.
3. Chemical Synthesis: DCTS can be used as a catalyst or reaction intermediate in organic synthesis.

The methods for preparing DCTS mainly include:

DCTS is obtained by reacting trimethylchlorosilane with trimethyltrichlorosiloxane.

DCTS safety information:

1. Please wear appropriate protective measures when using, such as gloves, goggles and protective clothing.
2. Avoid contact with the skin and inhalation of its vapor, such as contact should be immediately washed with water.
3. Avoid reacting with strong oxidants and strong acids, which may produce hazardous substances.
4. Storage should avoid direct sunlight and high temperature, should be stored in a ventilated and dry place.
