68956-54-7 - Introduction
By C4-unsaturated hydrocarbon is meant a hydrocarbon containing 4 carbon atoms and having unsaturated bonds. Common C4-unsaturated hydrocarbons include butene, isobutene and butadiene.
The properties of C4-unsaturated hydrocarbons include having a relatively low boiling point and flammability. They are colorless gas or liquid at room temperature and have a special smell. These compounds can react with oxygen in the air to form a combustible gas mixture that is explosive.
C4-Unsaturated hydrocarbons are widely used in industry. Butadiene can be used as the raw material of rubber, used in the manufacture of rubber shoes, rubber tube, tape and so on. Butenes and isobutene are also used to synthesize plastics, solvents and fuel additives, among others.
The preparation method of C4-unsaturated hydrocarbons is mainly obtained by cracking reactions in petroleum refining and petrochemical processes. Among them, a small amount of butene and isobutene is also produced in the ethylene cracking process.
When using and operating C4-unsaturated hydrocarbons, you need to pay attention to the following safety information. Due to its flammability, it must be kept away from open flames and high temperatures, and a well-ventilated environment must be maintained. Exposure to C4-unsaturated hydrocarbons may cause irritation and scalding, and appropriate protective measures, such as gloves and goggles, should be taken. During storage and transportation, corresponding regulations and requirements must be observed to ensure safety.
