The methylchlorosilanes react with water to produce hydrogen chloride, giving siloxanes. In the case of trimethylsilyl chloride, the hydrolyzed product is hexamethyldisiloxane: 2 ((CH 3) 3 SiCl + H 2 O → [(CH 3) 3 Si] 2 O + 2 HCl. The analogous reaction of dimethyldichlorosilane gives siloxane polymers or rings: n (CH 3) 2 SiCl 2 + n H 2 O ...
Trichlorosilane can cause hazardous chemical reactions with moisture and humidity alone, and should be handled and stored under inert gas. [8] Spills of trichlorosilane may be neutralized using a 1-1 ratio of sodium hydroxide , or a 2-1 ratio of sodium bicarbonate to trichlorosilane. [ 9 ]
TMSCl is reactive toward nucleophiles, resulting in the replacement of the chloride. In a characteristic reaction of TMSCl, the nucleophile is water, resulting in hydrolysis to give the hexamethyldisiloxane: + + The related reaction of trimethylsilyl chloride with alcohols can be exploited to produce anhydrous solutions of hydrochloric acid in alcohols, which find use in the mild synthesis of ...
Trichlorosilane is produced commercially by the reaction of hydrogen chloride with silicon: Si + 3 HCl → HSiCl 3 + H 2. Many alkoxy hydrosilanes are generated by alcoholysis of trichlorosilane. One example is triethoxysilane: HSiCl 3 + 3 EtOH → HSi(OEt) 3 + 3 HCl. Organohydrosilanes can be prepared by partial hydrosilation of silane itself:
Acid Chloride Preparative Route for Nylon-6,10, which is often used in the nylon rope trick. The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.

The crossed molecular beam technique was developed by Dudley Herschbach and Yuan T. Lee, for which they were awarded the 1986 Nobel Prize in Chemistry. [3] While the technique was demonstrated in 1953 by Taylor and Datz of Oak Ridge National Laboratory, [4] Herschbach and Lee refined the apparatus and began probing gas-phase reactions in unprecedented detail.
