Write the reaction equation: propane → propene → polypropylene.

Let us write down the reaction equations for the transformation chain:
C3H8 = C3H6 + H2 – dehydrogenation reaction, propene was obtained;
nH2C = CH2 – CH3 = (- CH2 – CH2 – CH3) n – the polymerization reaction occurs when heated to 70 degrees, under pressure in the presence of a TiCl3 catalyst, polypropylene is formed;
These reactions show the bond of alkanes, alkenes, high molecular weight compounds (polymers). The end product of the reactions – polypropylene is used in the manufacture of pipes, electrical insulation, and packaging material.
