Dichlorobis(2-ethylhexyl)silane(CAS: 1089687-03-5)

Dichlorobis(2-ethylhexyl)silane is a colorless to yellowish liquid with a molecular weight of approximately 242.25 g/mol. It has low solubility in water but is soluble in organic solvents. The compound is reactive, undergoing hydrolysis and substitution reactions. It is often stored in a nitrogen-purged environment to prevent oxidation and degradation.

Dichlorobis(2-ethylhexyl)silane is typically synthesized through the reaction of 2-ethylhexylsilanediol with chlorine gas, or by the chlorination of 2-ethylhexylsilane. The process involves the use of a catalyst, such as anhydrous zinc chloride, and high purity reagents to achieve high selectivity and yield. The product is then purified by distillation.

Dichlorobis(2-ethylhexyl)silane is used in various industries, including the production of silicone rubber and adhesives, as a curing agent in coatings, and in the synthesis of functional silanes for use in polymers and semiconductors. It is also employed in the manufacturing of sensors and as a precursor in the electronics industry.

When handling Dichlorobis(2-ethylhexyl)silane, it is important to use appropriate personal protective equipment (PPE), including gloves, safety glasses, and a respirator. Work should be conducted in a well-ventilated area, such as a fume hood, to minimize exposure. In case of a spill, immediate containment and clean-up procedures should be followed, and the Material Safety Data Sheet (MSDS) should be referenced for specific guidance.
