Thionyl chloride is a colorless or yellowish liquid under normal temperature and pressure. It has a pungent odor and is easy to decompose into sulfur dioxide and hydrogen chloride when meeting water. It is dissolved in benzene, chloroform and carbon tetrachloride and heated to 150 ℃ ° C starts to decompose, 500 °C is completely decomposed. Thionyl chloride can react with hydroxyl phenol or alcohol to form corresponding chloride; It reacted with Grignard reagent to form corresponding sulfoxide compounds. The molecular configuration of thionyl chloride is conical, in which the sulfur (VI) center contains a pair of lone pair electrons. Thionyl chloride is an important organic chemical intermediate, which is mainly used in medicine, pesticide, dye industry and organic synthesis industry as chlorinating agent. Pesticide industry is the main consumption field of thionyl chloride in China, which is mainly used in the production of antipotamide, pentrin, fenvalerate, fenvalerate, fenpropathrin, fenpropathrin, Isocarbophos, fenpropathrin, endosulfan, deltamethrin, methoxychlorpyrifos, oxazolidone, quizalofop and warfarin. Because thionyl chloride can strongly react with water, it can also react with hydrated salt of metal chloride to produce anhydrous metal chloride.

Selective post bud herbicide. The medicament is absorbed by the mixed stems and leaves, destroying the cell membrane and causing the weeds to dry up and die. It can effectively control broad-leaved weeds in soybean, cotton, peanut, rice, corn, grape and other crops.

Barium fluoride, colorless transparent cubic crystal; Slightly soluble in water, hydrochloric acid, nitric acid, hydrofluoric acid, and ammonium chloride aqueous solution; It is obtained by the interaction of barium carbonate and hydrofluoric acid; It has the characteristics of good moisture resistance, high temperature and good luminous performance. It can be used as window material or other optical components of carbon dioxide and other devices and the whole machine. Barium fluoride crystal with scintillation slow component suppression filter can be used in nuclear medicine, high energy physics, physical exploration and γ Ray astronomy. In addition, barium fluoride can also be used in the manufacture of optical glass, motor brushes, vacuum coating, laser generators, optical fibers, infrared light permeable films, welding fluxes, enamel manufacturing, solid lubricants, preservatives and pesticides.

It can be used as fertilizer, feed and medicine. It can also be used as food additive, toothpaste filler, etc. it can promote feed digestion and treat rickets, rickets, rickets and anemia of livestock
