Dioxane (also known as pentacyclic dioxide, cyclopentadienediol) is a chemical compound. The following is an introduction to the properties, uses, manufacturing and safety information of dioxane:
Properties: Dioxane is a colorless to light yellow liquid with a distinctive odor. It is insoluble in water, but soluble in alcohols, ethers and some organic solvents. It has a low density and is easily volatilized at room temperature.
Usage: Dioxane is commonly used as a solvent, used in the manufacture and treatment of coatings, inks, resins and other chemical products. It can also be used in the synthesis of organic compounds, such as environmental analysis, fine chemical synthesis and other aspects of research.
Preparation method: The preparation of dioxane is mainly obtained through the oxidation reaction of glutaric acid or amyl alcohol. One of the most common methods is to use oxygen or oxidizing agents to oxidize glutaric acid or amyl alcohol to dioxane.Colorless transparent liquid. The freezing point is -95ºC, the boiling point is 78ºC (100 kpa), the relative density is 1.066 (15/4ºC), the refractive index is 1.3974, and the flash point is 1ºC. It is miscible with water, soluble in alcohol, ether and benzene. Azeotrope formed with water, boiling point 70-73ºC, water content 6.7. It can decolorize bromine water.
