Sơ đồ điều chế PVC trong công nghiệp hiện nay là :

\[{C_2}{H_6}\mathop \to \limits^{C{l_2}} {C_2}{H_5}Cl\mathop \to \limits^{ - HCl} {C_2}{H_3}Cl\mathop \to \limits^{t^\circ ,p,xt} PVC\]

\[{C_2}{H_4}\mathop \to \limits^{C{l_2}} {C_2}{H_3}Cl\mathop \to \limits^{t^\circ ,p,xt} PVC\]

\[C{H_4}\mathop \to \limits^{1500^\circ C} {C_2}{H_2}\mathop \to \limits^{ + HCl} {C_2}{H_3}Cl\mathop \to \limits^{t^\circ ,p,xt} PVC\]

\[{C_2}{H_4}\mathop \to \limits^{C{l_2}} {C_2}{H_4}C{l_2}\mathop \to \limits^{ - HCl} {C_2}{H_3}Cl\mathop \to \limits^{t^\circ ,p,xt} PVC\]
