Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.
Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The relative humidity is kept below 75%. The packaging must be sealed and protected from moisture. It should be stored separately from acids and alcohols, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

It is reported that the Bavarian Chemical Cluster Association is Germany's largest network of chemical and research institutions and represents Germany's most creative chemical field. Dongying Economic and Technological Development Zone and Bazhou Chemical Industrial Zone respectively represent Shandong Province and Bavaria State to establish "International Chemical Cleaning Technology Innovation Clusters" and jointly carry out academic and economic cooperation in high and new technology. Take advantage of both scientific and economic resources to enhance competitiveness in high-efficiency energy technologies (including fossil fuels and renewable energy production and storage, biofuels), low-carbon technologies (including carbon capture and storage), advanced materials and smart surfaces , biotechnology, environmental technology, and health and comfort, innovation and other aspects of the common development. Through technical cooperation, we will further deepen the friendly relations between the provinces and the states of Lubata and promote the development and construction of the highly efficient ecological economic zone in the Yellow River Delta.
Dongying will build a global chemical clean high-tech center
On July 14, the Dongying Municipal Government signed a cooperation agreement with the Bavarian Chemical Cluster Association. The two parties will jointly build a global clean high-tech center and an “International Chemical Clean Technology Innovation Cluster†in Dongying.
