Uses: Isopropyl alcohol is an important chemical product and raw material, mainly used in pharmaceuticals, cosmetics, plastics, fragrances, and coatings.
Hazardous properties: Isopropyl alcohol is a colorless liquid that can be ignited at room temperature, and a mixture of isopropyl alcohol vapor and air will explode when heated. High concentrations of isopropyl alcohol vapor can cause coma, anesthesia, nausea, and other symptoms.
Storage precautions: Isopropyl alcohol is flammable and should be kept away from heat and fire sources during transportation and storage, and high-temperature environments should be avoided. Summer transportation should avoid transportation during the high-temperature period at noon, and the warehouse should be equipped with temperature control equipment. The vapor of isopropyl alcohol is combustible and explosive, and both transportation vehicles and warehouses should be cool and ventilated, vehicles should not be sealed, and warehouses should be equipped with ventilation equipment. During transportation and storage, isopropyl alcohol should be handled separately and should not be mixed with oxidants, acids, or alkalis in the same vehicle or warehouse area to prevent accidents.
Toxicological data: Isopropyl alcohol has better fat solubility than ethanol, so repeated contact has a drying effect on the skin. It can cause dizziness, headache, coma, and ingestion can cause nausea, hemoptysis, diarrhea, hypotension, circulatory failure, and persistent coma can cause hypothermia and death due to respiratory failure. It can also cause aspiration pneumonia, kidney and liver damage, especially greater kidney damage. LD50 Rat oral 5045 mg/kg, intraperitoneal injection 2736 mg/kg, intravenous injection 1099 mg/kg, mouse oral 3600 mg/kg, intraperitoneal injection 4477 mg/kg, intravenous injection 1509 mg/kg. No carcinogenic effect on humans, IARC classified it as 3.

Methylcyclohexane
Solvent, chromatographic reference material, thermometer calibration standard, also used in organic synthesis. Used as solvent for rubber, paint (including correction liquid), varnish, oil extraction solvent, etc.
Ethylcyclohexane
Used as raw material for organic synthesis, as solvent, chromatographic analysis standard material, etc., also used as metal surface treatment agent. Used as chemical intermediates and gas chromatographic comparison samples.
Cyclohexane
It is used as solvent of rubber, paint and varnish, thinner of adhesive and oil extractant. Because of its low toxicity, it is often used instead of benzene for degreasing, degreasing and depainting. This product is mainly used for the manufacture of nylon monomer adipic acid, adipdiamine and caprolactam, also used as a raw material for the manufacture of cyclohexanol, cyclohexanone; Used as an analytical reagent, such as a solvent, as a standard substance for chromatographic analysis. Also used in organic synthesis; Complexometric titration of copper, iron, silicon, aluminum, calcium, magnesium, etc. Chromatographic analysis standard; Used as a solvent for photoresist; Used for extraction of essential oils.
Toluene
Toluene is mainly made from crude oil through the petrochemical process. As a solvent it is used in oils, resins, natural rubber and synthetic rubber, coal tar, asphalt, cellulose acetate, as a solvent for cellulose paints and varnishes, as well as for photographic plate, ink solvent. Toluene is also the main raw material for organic synthesis, especially benzoyl chloride and phenyl, saccharin, trinitrotoluene and many dyes. It is also a component of aviation and automotive gasoline. Toluene is volatile and does not react well in the environment. It may eventually be degraded by biological and microbial oxidation because of its widespread distribution in the environment and its water-breaking recirculation between air and water by rain and evaporation from the water surface. A summary of average concentrations in the air of many cities around the world shows that toluene concentrations typically range from 112.5 to 150μg/m3, mainly from gasoline-related emissions (vehicle exhaust, gasoline processing), as well as from solvent losses and emissions from industrial activities.
Ethylbenzene
Mainly used in the production of styrene, and then the production of styrene homopolymer and styrene AS the main component of copolymer (ABS, AS, etc.). Ethylbenzene is used in a small amount in the organic synthesis industry, such as the production of acetophenone, ethyl anthraquinone, p-nitroacetophenone, methyl phenyl ketone and other intermediates. Used in medicine as an intermediate between comycin and chloramphenicol. Also used in spices. In addition, it can also be used as a solvent.
Chloroethylene carbonate
Vinyl chloride carbonate is mainly used in the preparation of lithium battery electrolyte vinyl fluoride carbonate and vinyl carbonate grease. High purity vinyl chloride carbonate can also be directly used as a flame retardant additive for lithium battery electrolyte to improve the cycle performance and prolong the service life of lithium battery electrolyte.
Vinylene carbonate
It is a new organic film forming additive and overcharge protection additive for lithium ion battery. It has good high and low temperature performance and anti-bloating function, which can improve the capacity and cycle life of battery. Vinyl carbonate can also be used as a monomer for the preparation of polyvinylene carbonate.
