Toluene is a colorless, clear liquid. Have a benzene-like smell. Strong refraction. It is miscible with ethanol, ether, acetone, chloroform, carbon disulfide and glacial acetic acid, and is very slightly soluble in water. The relative density is 0.866. Freezing point -95 ° C. The boiling point is 110.6 ° C. The refractive index is 1.4967. Flash point (closed cup) 4.4 °C. Flammable. Vapor can form an explosive mixture with air with an explosion limit of 1.2% to 7.0% by volume.
Toluene is widely used as a solvent and high-octane gasoline additive. It is also an important raw material for organic chemicals. However, compared with benzene and xylene obtained from coal and petroleum at the same time, the current production is relatively surplus, so a considerable amount of toluene is used for the removal. The alkyl group is benzene or deuterated to produce xylene. A series of intermediates derived from toluene, widely used in dyes; pharmaceuticals; pesticides; explosives; additives; the production of fine chemicals such as perfumes, also used in the synthetic materials industry.
The main hazards and common harmful factors in the production process are: flammable, mixed with air can become an explosive mixture. There is a danger of fire and explosion when exposed to fire, high temperature and strong oxidants. Its steam is heavier than air, and it can spread farther down the low point, and it will burn back when it is exposed to fire. It has mild irritating effect on skin and mucous membrane and anesthesia effect on central nervous system. Toxic, the maximum allowable concentration in the air of the workshop is 100mg/m3.
Health hazard: Irritating to skin and mucous membranes, anesthetic effect on the central nervous system.
Acute poisoning: Inhalation of higher concentrations in a short period of time may cause obvious irritation of the eyes and upper respiratory tract, conjunctival and pharyngeal congestion, dizziness, headache, nausea, vomiting, chest tightness, weakness of the limbs, gait, and confusion. Severe cases may have convulsions, convulsions, and coma.
Chronic poisoning: long-term exposure can occur neurasthenia syndrome, hepatomegaly, menstrual abnormalities of women workers. Dry skin, chapped, dermatitis.
Environmental hazard: It has serious harm to the environment and can cause pollution to air, water environment and water source.
Explosion hazard: the product is flammable and irritating
Testing equipment: toluene gas detector
Door Holders and door stopper is with the same function of holding the doors at one position. However, the main difference is door stopper is mainly used on floors while door holder is installed on walls.
