Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, colorless and odorless transparent liquid at room temperature, soluble in ethanol, propanol, benzene and chloroform and other most organic matter, known as the “universal solvent”. Due to the special status of dimethyl sulfoxide “universal solvent”, the industry has paid more attention to this product. The market situation of DMSO was briefly analyzed in this paper. 1. What are the production processes of dimethyl sulfoxide? According to the investigation, the DMSO production process is divided into methanol carbon disulfide method, hydrogen peroxide method, nitrogen dioxide method, dimethyl sulfate method and solution recovery method. At present, the mainstream production process is methanol carbon disulfide method, that is, methanol and carbon disulfide to produce dimethyl sulfide, and then with nitrogen dioxide to produce dimethyl sulfoxide. The mainstream process route is as follows: Figure 1 Process flow chart of methanol carbon disulfide process FIG. 2 Hydrogen…

Chemical formula difference:       Lithium hydroxide LiOH molecular weight :24        Molecular weight of Lithium hydroxide monohydratee LiOH-H2O :42        So you just multiply the weight of lithium hydroxide in a single water by 24/42=4/7        The lithium hydroxide content of a single water multiplied by four-sevenths is the net lithium hydroxide content. 　　The difference between lithium hydroxide monohydrate and lithium hydroxide 　　Introduction 　　In the field of chemistry, lithium hydroxide (LiOH·H2O) and lithium hydroxide (LiOH) are two common compounds that share many aspects in common, but there are some key differences. In this paper, the properties, applications and differences in practical applications of lithium hydroxide and lithium hydroxide are discussed in detail. 　　Qualitative distinction 　　1. Chemical formula and molecular structure 　　The chemical formula of lithium hydroxide is LiOH·H2O, which is composed of one molecule of water and one molecule of lithium hydroxide.…
