クロロ（メチル）シラン 化学特性,用途語,生産方法
定義
One of several intermediates in the formation of silicones or siloxanes,
they react with hydroxyl groups on many types of
surfaces to produce a permanent, thin-surface film
of silicone that imparts water repellency. Examples
are methyltrichlorosilane, dimethyldichlorosilane,
and trimethylchlorosilane.
一般的な説明
Methyl chlorosilane is a colorless gas with a distinctive odor. Chloromethyl silane is insoluble in water. Its vapors are heavier than air. Contact with the material causes severe irritation to skin, eyes, and mucous membranes. Chloromethyl silane is toxic by ingestion and skin absorption. Chloromethyl silane is also a dangerous fire risk. Chloromethyl silane is used to make water repellent materials. Prolonged exposure of container to fire or intense heat may result in their violent rupturing and rocketing.
空気と水の反応
Highly flammable. Based on the properties of similar materials, there is the possibility that the reaction of Chloromethyl silane with water may be vigorous or violent. Products of the reaction include hydrogen chloride. The reaction generates heat and this heat may be sufficient to ignite the product. The chlorosilicon hydrides (ClxSiHy) are spontaneously flammable in air [NFPA 1991].
反応プロフィール
Chlorosilanes, such as Chloromethyl silane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.
危険性
Toxic by ingestion and inhalation, strong
irritant to skin and eyes.
健康ハザード
TOXIC; may be fatal if inhaled or absorbed through skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
火災危険
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard.
