Analysis of the price trend of cyclohexanone in 2020

In 2020, the overall performance of the domestic cyclohexanone market is fluctuating in the first half of the year and stabilizing in the second half of the year. Compared with the trend of the cyclohexanone market in the same period last year, the overall situation is low and the profit margin is narrow. In 2019, the high price of cyclohexanone in the market appeared in March, the high price in the East China market reached 11,350 yuan/ton, and the low price appeared in early December, the low price in the East China market was 7,650 yuan/ton, and the price difference was 3,700 yuan/ton. In 2020, the high price of cyclohexanone appears in January, and the high price in East China market is RMB 7,700 / ton, while the low price appears in early April. The low price in East China market is RMB 4,850 / ton, and the price difference is RMB 2,850 / ton. It can be seen that in the first half of 2020, both high and low prices of cyclohexanone market are significantly lower than last year, while the price difference is lower than last year.

2020 cyclohexanone market as a whole, in general, affected by the epidemic and the supply and demand weak, at the beginning of 2020 domestic outbreak, macroeconomic volatility, raw materials and pure benzene prices for crude oil have been hit, factory shutdown, and return to work slowly and superposition of high-speed road closed, transport of goods is restricted, cyclohexanone market downturn, once the follow-up international outbreak, cargo export orders, market malaise. In the second quarter, pure benzene, the market is advancing, cyclohexanone downstream chemical fiber orders increase, increase work load caprolactam plant, the rise in demand, cyclohexanone market strong upward, but with weak movements of pure benzene, cyclohexanone plant restart or negative run, spot market, combined with the downstream chemical fiber demand reduction, high resistance, purchase will drop, orders, cyclohexanone, and the price is difficult to maintain, market price fluctuations. In the second half of the year, the peripheral news tends to be stable, the price range of raw material pure benzene fluctuates, the single demand of downstream chemical fiber is stable, the solvent is small on demand, and the market price fluctuation space of cyclohexanone is narrowed.

Physical properties

Cyclohexanone is an organic compound, the chemical formula is (CH2)5CO, is the carbonyl carbon atoms included in the six-membered ring of saturated cycloketone. A clear colorless liquid with an earthy flavor or, when containing a trace amount of phenol, a mint flavor. Impurity Chemicalbook material is light yellow, with storage time to form impurities and color, water white to grayish yellow, with a strong pungent odor. Slightly soluble in water, can be mixed soluble in alcohol, ether, benzene, acetone and other organic solvents. Mixed with air, the explosion pole is the same as the open chain ketone

Chemical properties

This product is flammable and has the risk of burning in case of high heat and open flame. May react violently on contact with an oxidant. In case of high heat, the pressure in the container increases, there is a risk of cracking and explosion. Same as open chain ketone. Hooc (CH2) 4CochemicalbookOH adipic acid was produced by oxidation of cyclohexanone with air, oxygen or nitric acid in the presence of the catalyst. Cyclohexanone oxime is rearranged in the presence of acid to form caprolactam. They are the raw materials for Nylon 66 and Nylon 6 respectively. Cyclohexanone is prone to self-condensation reaction in the presence of alkali. It also reacts easily with acetylene. Cyclohexanone was first obtained by the dry distillation of calcium heptanate. Mass production of cyclohexanone is a method of hydrogenation and oxidation catalyzed by phenol.

The main purpose

Cyclohexanone is an important chemical raw material and industrial solvent, and is the main intermediate in the manufacture of nylon, caprolactam and adipic acid. Also important industrial solvents, such as for paint, especially for those containing nitrocellulose, vinyl chloride polymer and its copolymer or methacrylate polymer paint, etc. Excellent solvent of ChemicalBook for organophosphorus insecticides and many similar pesticides, as a solvent for dyes, as a viscous solvent for piston-type aviation lubricants, as a solvent for fats, waxes and rubbers. Also used for dyeing and fading silk homogenizer, polishing metal degreasing agent, wood coloring paint, can be used cyclohexanone film, decontamination, spot removal.

The production process

Cyclohexanone is a very widely used petrochemical raw materials, is also an important organic solvent, cyclohexanone according to its use is often divided into amide and non amide used two categories. Cyclohexanone for amide is mainly used in the manufacture of caprolactam and adipic acid, which are important raw materials for the manufacture of fiber PA6 and engineering plastic PA66. At the same time, cyclohexanone is an important industrial solvent and can also be used in the production of pharmaceutical intermediates. At present, there are three production methods of cyclohexanone: cyclohexane oxidation method, phenol hydrogenation method and cyclohexene water method. Hydrogenation of phenol was the earliest Chemicalbook technique used in the industrial production of cyclohexanone. Cyclohexane oxidation in industrial production has two oxidation process routes, one is catalytic oxidation process, the other is no catalytic oxidation process. The catalytic oxidation process mainly uses cobalt salt, boric acid or metaboric acid as catalyst. In the 1980s, Japan Asahi developed the process of water synthesis of cyclohexene to produce cyclohexanol. The process is based on incomplete hydrogenation reaction of benzene to prepare cyclohexene. Cyclohexene is hydrated to form cyclohexanol. The by-product of the process is cyclohexane. The process has low consumption, and effectively avoids the waste lye produced in the process of cyclohexane oxidation, reduces the pressure of environmental protection, and has a clear prospect.
