[Encyclopedia of Chemical Engineering]:What are the top five domestic manufacturers of isopropanol

Isopropanol is an organic compound with the molecular formula of C3H8O. It is an isomer of n-propanol, also known as dimethyl methanol and 2-propanol. It is also known as IPA in the industry. It is a colorless transparent liquid, flammable, and has an odor similar to the mixture of ethanol and acetone. It is soluble in water, alcohol, ether, benzene, chloroform and other organic solvents.


Isopropyl alcohol is an important organic chemical raw material and organic solvent, which is widely used. Paint and ink are its main application fields. Other applications include antibiotic extractants, pharmaceutical capsule cleaning agents, electronic device cleaning agents, pesticide solvents, surfactants, etc. It is exported to Japan, the United States, Southeast Asia and other countries. With the development of new production technologies and the continuous expansion of application fields, Isopropyl alcohol, a chemical product, will have a broader market prospect


At present, the propylene hydration method accounts for about 25%, the acetone hydrogenation method accounts for about 56%, and the isopropyl acetate hydrogenation method accounts for about 19% of the isopropyl alcohol production process in domestic plants. Although there has been a trend of three powerful processes, acetone hydrogenation process will still be the main production process in the domestic market in the future according to the process maturity and use proportion. With the continuous increase of domestic isopropanol production capacity, the market supply and demand, the price fluctuation of raw propylene and acetone, etc. will make the game of production process more intense.

Which isopropanol manufacturers are there in China (top five manufacturers)


Next, let's sort out the companies of the top five isopropanol manufacturers in China, and look forward to the development of isopropanol in the future.


1. Shandong Dadi Supu Chemical Co., Ltd


Shandong Dadi Supu Chemical Co., Ltd. was established in October 2012. The company is located in the Marine Chemical Park, Houzhen Town, Shouguang City, Shandong Province. It covers an area of 102 mu, has a registered capital of 65.4 million yuan, and the first phase of the project has an investment of 80 million yuan. It was put into operation in October 2013, with more than 60 employees. At present, it mainly produces high-quality isopropanol, with an annual output of 100000 tons and an output value of 800 million yuan (RMB)


Isopropyl alcohol production capacity: 100000 tons


2. Jinzhou Petrochemical Co., Ltd


PetroChina Jinzhou Petrochemical Company is a key refining and chemical enterprise under PetroChina Co., Ltd. Located in the western Liaoning corridor, bordering Bohai Bay in the south, Jinzhou is the central city of western Liaoning. The Beijing Shenyang, Beijing Harbin, Beijing Dalian Railway and Beijing Shenyang Expressway pass through the urban area, providing convenient sea, land and air transportation.


3. Jiangsu Kailing Chemical (Zhangjiagang) Co., Ltd


Kailing Chemical (Zhangjiagang) Co., Ltd. is one of the holding subsidiaries of Jiangsu Feixiang Chemical Group (hereinafter referred to as Jiangsu Feixiang Group). It mainly applies advanced high-pressure hydrogenation technology to produce green organic solvents, including isopropyl alcohol, ethanol, CHDM, isopropyl acetate and other products


4. Dongying Haike New Energy Chemical Co., Ltd


Founded in October 2002, it is referred to as "Haike Xinyuan". It is located in Shandong Dongying Provincial High tech Industrial Development Zone. It has two production bases in Shandong and Jiangsu, with 500+employees. Over the past 20 years, it has focused on the research, development, production and sales of lithium ion battery electrolyte solvent and high-end propylene glycol, dipropylene glycol, 1,3 butanediol and other fine chemicals, and the products are widely used in lithium battery materials, medicine, daily chemicals, essence spices, basic chemistry and other fields


5. Zhejiang Xinhua Chemical Co., Ltd


Founded in 1967, formerly known as the state-owned Xin'anjiang Chemical Fertilizer Plant, Jiande Xinhua Chemical Co., Ltd. was restructured in 1997 and established as a joint-stock company in 2008. The company's shares were listed on the main board of the Shanghai Stock Exchange in 2019, stock code: 603867. The company has established four modern production bases in Zhejiang, Jiangsu, Jiangxi and other places, and its products include organic amine series (C2 - C8 low carbon fatty amine), essence flavor, organic phosphorus, peroxide, synthetic ammonia, new materials, surfactants and other fine chemicals


Compared with other countries, the application field of isopropanol in China has not been effectively developed, and further development is needed to promote the steady development of isopropanol. In foreign countries, isopropanol is mostly used to disinfect skin, artificial limbs and medical servers. In some countries, it is the most widely used disinfectant in beauty parlors and other public cultural places, but in China, such technology is rarely used. From the perspective of effect, isopropyl alcohol contains two groups of methyl groups to make it capable of dissolving lipids. The immersion force is stronger than that of ethanol, and the contact ability is enhanced. The killing effect of some bacteria and viruses is stronger than that of ethanol. In addition, compared with traditional ethanol, isopropanol has a higher boiling point, less volatility, easier preservation, and safer and more reliable use. Novel coronavirus is widely spread around the world, and various medical protection materials are increasingly scarce, which greatly stimulates the demand for isopropanol at home and abroad.

The field of cleaning agent for electronic technology industry is one of the fastest growing areas of the global isopropyl alcohol consumption economy, and the demand is expected to grow at an annual rate of more than 10%. In the field of cleaning agents, high-purity isopropanol is mainly used as semiconductor cleaning agent and metal de esterifying agent. For example, in Japan, high-purity electronic grade isopropanol is an important microelectronic chemical reagent, which has been widely used in the manufacturing of semiconductor components, VLSI assembly, and cleaning and corrosion in the process. At present, the research on the application of isopropanol in this field in China has just started, and the economic development potential is huge.
