Acute poisoning may occur by inhalation of vapour. Irritant and corrosive to skin, eyes and mucous membranes, and can cause allergy through skin absorption.

Distillation is the use of SiCl4, and the difference between the relative volatility of impurities components, through several partial gasification and partial condensation process, to achieve the separation of mixed liquid, so as to obtain high purity silicon tetrachloride products.

The principle is to reduce high purity trichlorosilane with high purity hydrogen on the high purity silicon core at about 1100℃ to generate polycrystalline silicon deposited on the silicon core. On the basis of the traditional Siemens process, the improved Siemens process is equipped with a supporting process of energy saving, consumption reduction, recycling and utilization of a large amount of H2, HCI, SiCI4 and other by-products and a large amount of by-production heat energy.

SiCl4 is one of the most important inorganic silicon compounds, is a colorless, transparent, flowing smoke liquid, with suffocating odor, soluble in benzene, ether, chloroform and other most organic solvents. Silicon tetrachloride is a volatile liquid with strong asphyxiating odor. It can be used as raw materials for the production of gaseous silica, high purity silicon and organosilicide. The upstream of the silicon tetrachloride industry chain is the raw material market, mainly silicon powder, ferrosilicon, hydrogen chloride, etc.

High temperature hydrogenation of silicon tetrachloride is an important method to treat silicon tetrachloride as a by-product of polysilicon. High temperature hydrogenation is silicon tetrachloride and hydrogen as raw materials, heated by 1200 ~ 1250℃ graphite heater, thermal reduction reaction to produce  trichlorosilane. The advantages of the process are that the whole system is closed circulation, suitable for continuous and stable operation; Trichlorosilane products of high purity, need to distillation links less.

Trichlorosilane (TCS or SiHCl3) is generated as follows within a high temperature, pressurized reactor: Si + 3 HCl ➡ SiHCl3 + H2 ，Si + 3 SiCl4 +2 H2 ➡ 4 SiHCl3 .The TCS is then sent to the CVD (Chemical Vapor Desposition) reactor. In the Siemens process, high-purity silicon "starter" rods or hairpins are exposed to trichlorosilane at 1150 °C in the CVD reactor.

Cyclohexylamine has the chemical properties of a primary amine. Carbonates that are strongly alkaline and absorb carbon dioxide in the air to form white crystals. It can react with acyl chloride, anhydride and ester to form N-acyl. React with nitrite to give alcohol. Hydroxymethyl compounds are formed by reaction with formaldehyde in alkaline solution. Reacts with carbon disulfide to form dithiocarbamate. Reacts with aldehydes to form Schiff bases.This product is used to prepare cyclohexanol, caprolactam, acetate fiber and nylon 6, etc.

In recent years, China's polysilicon production has shown geometric development, but the disposal of polysilicon by-product silicon tetrachloride has become a difficult to step over the development of polysilicon industry "sill", let the silicon industry wear the hat of high pollution.

The process relates to a tail gas refining method, in particular to the hydrogenation of aniline to prepare cyclohexylamine and the deamination of dicyclohexylamine tail gas to refine hydrogen.
