Gas introduction
1.3-butadiene is an organic compound with a chemical formula of C4H6. It is a colorless gas with a slight aromatic odor. It is insoluble in water and soluble in most organic solvents such as acetone, benzene, acetic acid, esters, etc. It is a raw material for making synthetic rubber, synthetic resin, nylon, etc.
On October 27. 2017. the World Health Organization’s International Agency for Research on Cancer published a preliminary list of carcinogens for reference. 1. 3-butadiene is on the list of Class 1 carcinogens.
It is mainly used as raw material for manufacturing synthetic rubber, synthetic resin, nylon, etc.
