Acetylene acetylene GB6819-86 C2H2≥98.0% high purity acetylene GB6819-86 C2H2≥99.0% Physical characteristics: Formula: C2H2 triple point temperature: -80.55 ℃ (192.6K) density: 1.1747kg / m3 relative molecular mass: 26.038 production methods (industrial method): calcium carbide method (calcium carbide, the common name response "carbide" with water to produce) main properties: explosive, slightly lighter than air, high heat of combustion, and generates copper, mercury, silver and other metals Easy explosive metal compound, caustic soda reacts with explosive compounds. Application: mainly used for heating and heat treatment, metal cutting, welding, instrumental analysis metals. Acetylene is one of the important basic organic type material, starting from acetylene thousands of compounds can be synthesized. Therefore, acetylene and its derivatives in the synthesis of plastics, synthetic fibers, synthetic rubber, pharmaceuticals, pesticides, dyes, perfumes, solvents, adhesives, surfactants, and organic conductors and semiconductors until many industries have wide applications. Packaging: Special acetylene cylinders for a nominal weight of 5 kg.
