Hydrogen sulfide downstream industry chain product dimethyl sulfoxide DMSO

As an excellent solvent, dimethyl sulfoxide is often used as a green solvent substitute in chemical synthesis. It dissolves many organic and inorganic compounds, including difficult-to-dissolve polymers, allowing some reactions to take place under milder conditions. Due to the continued growth in global demand, especially driven by the pharmaceutical industry and electronic materials industry, the DMSO market is expected to reach more than $150 million.

1. Application
Medicine: Dimethyl sulfoxide is also a useful pharmaceutical ingredient. It can promote drug absorption and penetration of the skin, so it is often used in drug anti-reflection agents, drug delivery agents and local anesthetics. Dimethyl sulfoxide is also used in biomedical research and in the manufacture of pharmaceutical intermediates.
Metalworking: dimethyl sulfoxide can also be used as an additive in metalworking fluids for cleaning, polishing and corrosion prevention of metal surfaces.
Electronic materials: dimethyl sulfoxide is more and more widely used in electronic materials. It can be used as a solvent in the preparation of optical glass and conductive film, and plays an important role in the manufacture of electronic products such as display screens.
Other fields: DSO can also be used in the preparation of fibers, resins and polymer materials, as well as chemical products such as dyes, pigments and printing inks.
2. Market trend forecast
With the aging of the global population and the increasing demand of the pharmaceutical industry, dimethyl sulfoxide plays an important role in the chemical synthesis reaction, and its application in the pharmaceutical process is more and more extensive. Therefore, the demand of the pharmaceutical industry will continue to grow.
With the continuous development of science and technology, the application of DSO in the electronics industry has been gradually expanded. At present, some people have begun to explore the application of dimethyl sulfoxide in battery electrolyte, which will provide new impetus for the growth of demand for dimethyl sulfoxide.
Due to the toxicity and environmental harm of DSO in the manufacturing process, the regulation of the environmental protection industry is gradually strengthened, and the use of DSO will be limited. However, at the same time, the environmental protection industry will also become an important demand side of DSO, especially in paint solvents and wastewater treatment, and its application prospects are broad.
Based on the above analysis, it is expected that the demand of DSO market will continue to grow in the future, but the demand structure will also change. It is suggested that relevant enterprises should pay attention to some key factors of market demand when formulating development strategies, and strengthen research and development efforts to expand the use of products in order to seize market opportunities.
Iii. Process overview
DMSO process is a high value-added method to recover sulfur by using acid gas produced by coal chemical industry, synthetic ammonia, refinery gas, natural gas processing and other gases containing hydrogen sulfide (H2S). First, H2S in acid gas is converted into dimethyl sulfide DMS by reaction with methanol.
H2S+2CH3OH→(CH3)2S+2H2O
After this reaction, dimethyl sulfide (DMS) products can be obtained by refining. By adding oxygen and nitrogen dioxide gas, the intermediate product DMS can be transformed into DMSO under the action of the catalyst, and DMSO products can be obtained after refining. The main reaction formula is as follows:
(CH3)2S+1/2O2→(CH3)2SO
At present, the dimethyl sulfoxide market price is 25,000-33,000 yuan/ton, the highest output of a single set of DMSO is 10,000 tons, the annual output of 20,000 tons of DMSO investment is about 300 million, the ton cost is less than 10,000 yuan, and the economic benefits are significant.
