process

The polymerization of the Ziegler-Natta catalyst is a useful and adaptable process for generating polymers. ${\mathrm{TiCl}}_3$ is one of the most well-known uses of this catalyst.
The suggested catalytic cycle(Figure 1) starts with the complexation of ${\mathrm{PdCl}}_2$and two chloride anions to${\mathrm{PdCl}}_4$, which is nearly identical to that of the Wacker Process.
In this procedure, oxygen reacts with hydrogen chloride over a copper chloride catalyst to produce chlorine.
Vanadium oxide, often known as ${\mathrm{V}}_2{\mathrm{O}}_5$, serves as a catalyst in contact processes.
