Description :

　　Overview: 1,4-dioxane is a six membered heterocyclic compound containing two oxygen heteroatoms. It is a colorless and flammable liquid with a slight ether like odor. Sensitive to light. Steam easily absorbs oxygen in the air to form explosive peroxides. The explosion limit is 1.97% -22.5% (volume), and it should be treated with a reducing agent during distillation. Melting point 11.8 ℃, boiling point 101 ℃ (750 mmHg), relative density 1.0337 (20/4 ℃). Dissolve in organic solvents such as water and ethanol. It can form an azeotropic mixture with water (containing 18.6% water), with a boiling point of 87.8 ℃. The reaction appears bright yellow. Trace amounts of 2,6-di-tert-butyl-p-cresol (BHT) are often added as stabilizers in daily purchased goods.

　　The preparation of 1,4-dioxane can be achieved by dehydrating ethylene glycol with sulfuric acid, and it is also an indirect product in the production of ethylene oxide.

　　1,4-dioxane is an excellent organic solvent with a wide range of applications. It can be used as a solvent for cellulose acetate and many resins. It is mainly used as an extractant in the industry, as a stabilizer in the production of 1,1,1-trichloroethane, and as a volatile solvent in the production of polyurethane synthetic leather, replacing dimethylformamide. Used as a stripping agent in paint and coating processes. Used as a solvent and dispersant in the dye industry. As a stabilizer in printing ink. And it can be used as a metal surface treatment agent, as well as in cosmetics, fragrance manufacturing, electroplating, and other fields.

　　Chemical properties: Colorless liquid. Freezing point 11.80 ℃, boiling point 101.32 ℃ (100kPa), relative density 1.0336 (20/4 ℃), refractive index 1.4224, flash point 12 ℃. Can be miscible with water and most organic solvents. When there is no water, explosive peroxides are easily formed. There is a refreshing ester flavor. This product is used as a solvent, reaction medium, and extractant in the manufacturing of special fine chemicals such as cosmetics and fragrances, as well as in research. In Japan, this product is mainly used as a stabilizer for 1,1,1-trichloroethane, with an added amount of 2.5-4%; Secondly, it is widely used as a reaction solvent for polyurethane synthetic leather, amino acid synthetic leather, and other applications. This product has strong solubility and is similar in strength to others. The following uses of dioxane are worth noting: (1) it forms complexes with sulfur trioxide and can be used as a sulfating agent in the synthesis of many compounds; (2) Used for the extraction of pesticides, dewaxing of petroleum products, etc; (3) Used as a dispersant for dyes, wood coloring agents, and solvents for oil soluble dyes; (4) Used as a high-purity metal surface treatment agent, etc. This product is irritating to the skin, lungs, and mucous membranes. Severe poisoning can damage the liver and kidneys.

　　Used as a solvent for cellulose acetate, resins, vegetable oils, mineral oils, soluble dyes, etc., used in the production of paints, varnishes, plasticizers, lubricants, etc. Used as a chromatographic analysis reagent and solvent for cellulose acetate and its derivatives. Used as a solvent for cellulose acetate, vegetable oils, mineral oils, soluble dyes, etc., used in the production of paints, varnishes, plasticizers, lubricants, etc. It has the general characteristics of ethers and is mainly used as an extractant in organic synthesis, a stripping agent for paints, a dye solvent and dispersant, and as a substitute in polyurethane synthetic leather.
