Hexamethylcyclotrisiloxane USES preparation method with sulfonated, isopropyl benzene, chlorobenzene hydrolysis method, crude phenol refining method, oxidation of benzene and toluene oxidation method of six. Our country mainly uses sulfonated method and isopropyl benzene method.

The sulfonation method takes benzene as raw material, produces benzene sulfonic acid by sulfonation with sulfuric acid, neutralizes with sulfite, and then melts with caustic soda. It is prepared by steps such as sulfonation and vacuum distillation.

Isopropylbenzene method is propylene and benzene under the action of aluminum trichloride catalyst to produce isopropylbenzene, isopropylbenzene after oxidation to isopropylbenzene peroxide, and then with sulfuric acid or resin decomposition. At the same time get hexamethylcyclotrisiloxane USES and acetone. Per ton hexamethylcyclotrisiloxane USES combined acetone about 0.6 t.

Hexamethylcyclotrisiloxane USES is an important organic chemical raw materials, and use it to preparing phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, 2, 4-d, adipic acid, phenolphthalein n-acetyl ethoxy aniline and other chemical products and intermediates, In chemical raw materials, alkyl phenols, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings and oil refining industry has an important use.

Hexamethylcyclotrisiloxane USES also can be used as a solvent, laboratory reagents and disinfectant, hexamethylcyclotrisiloxane USES aqueous solution can make chromosomes in plant cells, proteins and DNA separation, easy dyeing was carried out on the DNA.
