Description

Acetylene, commonly known as wind coal or calcium carbide, is the smallest of the alkynes and is a colorless, highly flammable gas at room temperature. Acetylene for industrial use contains impurities such as hydrogen sulfide and phosphine, and has a smell of garlic.

For oxyfuel cutting, heat treating and torch brazing applications

Acetylene is a flammable gas produced by the reaction of calcium carbide with water or as a by-product of ethylene production. Acetylene is dissolved in a solvent in a specially designed cylinder filled with a porous substance. Because the gas dissolves in matter, it is sometimes called “dissolved acetylene”.

Acetylene’s extremely high flame temperature (3100°C) makes it ideal for oxyacetylene cutting, heat treating and torch brazing. It is also used in organic synthesis in analytical laboratories and as a flame gas in analytical techniques such as atomic absorption (AA) spectroscopy. Sometimes it is used for chemically induced flower production.

Application

Cutting and welding meta.

Basic raw materials of manufacturing of acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fiber and other.

High purity acetylene can be used in some experiments.
