Introduction to acetylene

Acetylene, molecular formula C2H2, acetylene molecular weight 26.038; molar volume under standard state 22.223L. Commonly known as acetylene and calcium carbide gas, it is the smallest member of the alkyne compound series and is mainly used for industrial purposes. Acetylene (Acetylene) is one of the important raw materials for organic synthesis and one of the three major synthetic materials (synthetic rubber, synthetic fibers and plastics). ) one of the monomers.

Applications of acetylene

Acetylene is widely used as an efficient and high-quality high-temperature heat source in metal welding, cutting, spraying, surface quenching and thermal processing. Acetylene burns in air or oxygen, and its flame temperature can reach over 3200°C. Although the combustion heat of acetylene is slightly lower than that of ethane, ethylene, etc., the oxygen consumption during complete combustion is the least. The water content in the product is relatively low, and the heat loss required for water evaporation is less, so acetylene can burn Obtaining higher temperatures is the irreplaceable and remarkable feature of acetylene. Especially when it comes to welding metals. Acetylene is a colorless, highly flammable gas at room temperature.

Properties of acetylene

Pure acetylene is an odorless flammable gas with a colorless aromatic odor. Acetylene made from industrial acetylene carbide is toxic because it is mixed with hydrogen sulfide H2S, phosphine PH3, and arsine, and has a garlic smell. And it has a special odor.

Autoignition point is 305℃. The explosion limit in air is 2.3%-72.3% (vol). There is a risk of violent explosion in the liquid and solid state or in the gaseous state and under a certain pressure. Heat, vibration, sparks and other factors can cause explosions, so it cannot be stored or transported after pressurized liquefaction. Slightly soluble in water, soluble in ethanol, benzene and acetone. At 15°C and 1.5MPa, the solubility of acetylene in acetone is 237g/L, and the solution is stable.

Our Acetylene gas holder

Acetylene gas holder for industrial equipment is a device for storing acetylene gas, commonly used in industrial and laboratory environments. The main function of Acetylene gas holder for industrial equipment is to store and supply acetylene gas to meet the needs of the industrial production process. Acetylene gas holder for industrial equipment is usually made of welded steel plates and has a vertical or horizontal shape. There are usually partitions or fillers inside to increase gas storage capacity and stability. The capacity of Acetylene gas holder for industrial equipment is determined according to actual needs, ranging from hundreds to thousands of liters.
