What is oxygen? What is acetylene?

Oxygen (chemical formula: 32.00) is a colorless and odorless gas and the most common elemental form of oxygen. Melting point -2 18.4℃ and boiling point-183℃. Insoluble in water, about 30mL of oxygen is soluble in 1L water. Oxygen accounts for about 2 1% in the air. Liquid oxygen is sky blue. Oxygen fixation is a blue crystal. It is not very active at room temperature and does not easily react with many substances.

Acetylene, commonly known as wind coal and calcium carbide gas, is the smallest member of alkyne compound series, which is mainly used for industrial purposes, especially for welding metals. Acetylene is a colorless and highly flammable gas at room temperature.

Matters needing attention in acetylene operation of extended data:

Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear anti-static work clothes. Stay away from kindling and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Prevent gas from leaking into the air in the workplace. Avoid contact with oxidants, acids and halogens.

During transmission, gas cylinders and containers must be grounded and bridged to prevent static electricity. Lightly load and unload during handling to prevent damage to gas cylinders and accessories. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment.
