Solubility: Insoluble in water, soluble in ethanol, ether, acetone, benzene, petroleum ether, carbon tetrachloride and so on.
Uses: 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.
Environmental hazard: It is harmful to the environment and can pollute water, soil and atmosphere.
Health hazard: skin contact can cause redness, dry chapping, ulcers and so on. No poisoning has been reported so far. In animal experiments, the toxicity of the product is similar to cyclohexane, but the anesthetic effect is stronger than cyclohexane.
Hazardous properties: Its vapor and air can form explosive mixtures. Risk of combustion and explosion in contact with heat source and open flame. It can react strongly with an oxidizing agent and cause combustion or explosion. In a fire, heated containers are in danger of exploding. After high-speed impact, flow and agitation, combustion and explosion can be caused by electrostatic spark discharge. Its vapor is heavier than air, can spread to a considerable distance at a lower place, in the event of an open flame will lead back to ignition. Combustion (decomposition) products: carbon monoxide, carbon dioxide.
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the warehouse should not exceed 30℃. Take measures to prevent static electricity. Keep the container sealed. Should be stored separately from oxidizer, do not mix storage. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.

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.
