Product use
is mainly used as a raw material of polyester fiber (polyester), and is used for other polyester resin, unsaturated polyester resin 1730 polyester paint. Various types of surfactants can be derived from ethylene glycol and polyethylene glycol. Its dinitro compound dinitroethylene glycol is an explosive. Ethylene glycol can reduce the freezing point of aqueous solution, so it is often used as an antifreeze. In addition, ethylene glycol is also used in the production of plasticizers, explosives, and the like.
Physicochemical properties
Colorless transparent viscous liquid, sweet and hygroscopic. Boiling point: 198 ° C, freezing point: -11.5 ° C. Density: 1.1136 purchasing power. Refractive index: 1.4318. Flash point: 116 ° C. Viscosity (20 ° C) 21. mPa.s. Specific solubility: (20 ° C) 2.35j / (g. ° C), molar heat of formation: -452.3kj / mol. Heat of dissolution: 187.025j / g. Heat of evaporation: 799.14j / g. Surface tension: (20 °C) 48.4mN / m. Vapor pressure (20 ° C) 7.999Pa, self-ignition point: 412.8 ° C. Ethylene glycol and water lower aliphatic alcohol, glycerin, acetic acid, acetone and similar ketones, aldehydes, pyridine and Similar coal tar alkali miscible, slightly soluble in ether, ethylene glycol is almost insoluble in benzene and its homologues, chlorinated hydrocarbons, petroleum ethers and oils. toxic protection: no serious toxicity to lower vertebrates, but Humans are different. Due to the high boiling point of ethylene glycol and low vapor pressure, there is generally no inhalation poisoning. The amount of infiltration into unbroken skin is small. It can cause irritation to the eyes. A large number of citations will stimulate the central nervous system, causing difficulty in breathing, kidney bleeding, pneumonia, etc. The person who was mistakenly took the potassium permanganate solution for gastric lavage and catharsis. Severe cases are sent to the hospital for treatment.
Packaging and storage:
200L standard plastic drum, 220kg/barrel.
Ethylene glycol should be sealed during storage and transportation. It should be stored and transported according to general chemical regulations for long-term storage using nitrogen seal, moisture proof, fire prevention and antifreeze. |
