Usage

General Description

2-Chloroethoxytrimethylsilane is a chemical compound with the molecular formula C5H12ClOSi. It is a colorless liquid with a strong odor and is highly flammable. 2-Chloroethoxytrimethylsilane is primarily used as a coupling agent and intermediate in the production of silicone resins, coatings, and adhesives. It is also utilized as a processing aid in the manufacturing of various industrial products. Additionally, it can act as a silane coupling agent in bonding glass fibers to siliceous materials, improving the overall strength and durability of composite materials. However, 2-Chloroethoxytrimethylsilane poses several health hazards and should be handled with care, as it is corrosive to the skin and can cause severe eye irritation. It should be stored in a cool, well-ventilated area away from heat and incompatible materials.

Silicon-29 NMR spectra of trimethylsilylated alcohols

29Si NMR spectra of trimethylsilyl (TMS) derivatives of 26 simple alcohols were measured under standardized conditions (i.e., in sufficiently diluted deuteriochloroform solutions). Due to association with the solvent the chemical shifts are in almost all cases larger than those reported earlier for different solutions. This observation is in agreement with the proposed mechanism of steric effects as being due to sterically controlled association with the solvent. The use of chloroform as a solvent enhances steric effects hut at the same time it can reduce small differences due to polar effects in closely related compounds. In the studied class of compounds the gross dependence of the chemical shift on polar effects is not substantially affected by the change of the solvent.

PROTECTION OF ALCOHOLS AND ACIDS WITH ALLYLSILANES CATALYZED BY IODINE OR IODOTRIMETHYLSILANE IN CHLORINATED HYDROCARBON

Many triorganosilyl ethers and esters were prepared by the reaction of allylsilanes with alcohols catalyzed by iodine or iodotrimethylsilane in excellent yields.Bromine and bromotrimethylsilane were also effective catalysts.
