Used For Specialty Glass For Intermediate In The Chemical , 99.95% Liquid C2H4 Ethylene Gas
Ethylene is perceived by a family of five transmembrane protein dimers such as the ETR1 protein in Arabidopsis. The genes encoding ethylene receptors have been cloned in the reference plant Arabidopsis thaliana and many other plants. Ethylene receptors are encoded by multiple genes in plant genomes. Dominant missense mutations in any of the gene family, which comprises five receptors in Arabidopsis and at least six in tomato, can confer insensitivity to ethylene. Loss-of-function mutations in multiple members of the ethylene-receptor family result in a plant that exhibits constitutive ethylene responses. DNA sequences for ethylene receptors have also been identified in many other plant species and an ethylene binding protein has even been identified in Cyanobacteria.
1. Physical properties
A divalent hydrocarbon group C2H4 derived from ethane
2. Test report
Ethylene should be used when combustible gas pressure relief valve (decompression table), and the detection of airtightness of the pipeline, the use of gas is strictly prohibited. Switch the gas valve when the action must be slow, no gas should be kept when the cylinder valve closed.
Used cylinders should be retained in accordance with the provisions of the residual pressure of more than 0.05MPa, flammable gas should be retained more than 0.2MPa residual pressure. All kinds of cylinders should be dedicated to the bottle, must be regularly carried out safety inspection.
