Vinylklorimonomeerit

Vinylklorimonomeerit, more commonly known as vinyl chloride monomer (VCM), is an organochlorine compound with the formula C2H3Cl. It is a colorless gas at room temperature and pressure, and it is highly flammable. VCM is a significant industrial chemical, primarily produced for the manufacture of polyvinyl chloride (PVC), a widely used plastic.

The production of VCM typically involves the cracking of 1,2-dichloroethane, which itself is produced by the chlorination of ethylene. Another method is the oxychlorination of ethylene. These processes are carried out on a large scale globally.

VCM is a precursor to PVC through a process called polymerization. In this process, individual VCM molecules link together to form long chains of PVC. PVC is a versatile material used in a vast array of products, including pipes, window frames, flooring, cables, and packaging.

Due to its inherent toxicity and carcinogenicity, strict safety regulations govern the handling, production, and transportation of VCM. Exposure to VCM can lead to serious health issues, including liver cancer. Industrial facilities that produce or use VCM employ extensive safety measures to minimize worker exposure and environmental release. Research and development efforts continue to focus on improving production efficiency and reducing the environmental impact associated with VCM.
