The purity of dicyclohexylamine is higher than 99.5%, which is 99% higher than the standard of peer enterprises. Recycling the industrial chain can reduce the comprehensive cost of the factory. There are three aniline factories in Dongying, Shandong, Huai 'an, Jiangsu and Tianji, Shanxi within 400 kilometers. The technology is mature, and the workers have about twenty years of practical experience.

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.

By controlling the parameters in each step, such as time, temperature, pressure, etc.The yield of cyclohexylamine products is high, the product yield is more than 99%, the quality is stable, the yield is high, the production capacity is large, the side reaction is less, and a small amount of by-product dicyclohexylamine in the reaction can be recovered and purified, and the added value of the products can be increased.

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.

It is obtained by catalytic reduction of nickel or cobalt from aniline at high temperature and pressure. Cyclohexanol can also be reduced by phenol, oxidized to cyclohexanone, and then aminated with ammonia to obtain cyclohexanamine.This substance is harmful to the environment, and special attention should be paid to the pollution of water bodies. Acute poisoning may occur by inhalation of vapour. Irritant and corrosive to skin, eyes and mucous membranes, and can cause allergy through skin absorption.

Trichlorosilane is mainly used in the manufacture of polysilicon and silane coupling agents, among which polysilicon is the most important downstream application area of trichlorosilane, accounting for 32% of the consumption in 2021, and silane coupling agent consumption accounted for 25%. The market is still in good condition.

With the rapid growth of downstream PV demand, photovoltaic grade trichlorosilane continues to be in short supply. The application of PV grade trichlorosilane in the production of polysilicon includes a one-time requirement for the first commissioning, which accounts for about 20% of the total capacity. Second, the requirement for chlorine supplementation during continuous production accounts for about 10 to 30 percent of total production. On the supply side, the expansion of trichlorosilane production has been conservative in the past.

To explore the application value of ion chromatography in the detection of cyclohexylamine in workplace air. Workplaces containing cyclohexylamine in the production of raw materials were selected as sampling sites, and the content of cyclohexylamine in workplaces was detected by ion chromatography. At the same time, the precision and recovery rate of ion chromatography, desorption efficiency, sampling efficiency and other cation interference characteristics were analyzed.

It is obtained by catalytic hydrogenation of aniline and can be divided into atmospheric pressure method and pressure method. In addition, cyclohexamine can be prepared by catalytic ammonolysis of cyclohexane or cyclohexanol, reduction of nitrocyclohexane, and catalytic ammonolysis of cyclohexanone in the presence of hydrogen.The refining process often contains impurities such as aniline and water.

Cyclohexylamine (CHA) is a primary amine, can be miscible with water with infinite ratio, the molecule is small, easy to adsorb on the metal surface, its shielding effect is better than long chain primary amine and secondary amine, so it can effectively prevent the invasion of corrosive ions, thereby improving corrosion resistance, especially the ability to inhibit corrosion.The corrosion inhibition of 304 stainless steel by cyclohexylamine in sodium chloride medium was studied in detail.

Foreign production and application are mainly concentrated in the western developed countries and regions, the main manufacturers are the United States Air Products company, Celanes company, Germany BASF, Bayer company and other scale manufacturers. But in Europe, cyclohexylamine has been in short supply due to the limitation of hydrogen feedstock. With the rapid development of the food additive cyclamate and rubber industry, the consumption of cyclohexylamine has been increasing at an average annual rate of more than 10%.

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.

Silane coupling agent product price growth is very obvious, compared with the same period last year growth of 118%. Upstream raw material trichlorosilane price rise, silane products for the high price operation provides a strong support. Reporters learned that trichlorosilane is mainly used in the production of polysilicon, silane coupling agent, silane coupling agent is the second largest downstream market of trichlorosilane, in recent years the demand is more exuberant.

Silicon tetrachloride is mainly used in the manufacture of silicone esters, gaseous silica, silicone monomer, silicone oil, high temperature insulating paint, silicone resin, silicone rubber and so on. High-purity silicon tetrachloride is the main raw material for manufacturing fiber prefabricated rod, and the quality of fiber prefabricated rod directly determines the fiber performance.
