Question

What function does the activated alumina play in purifying the monomer and why is this step important ?

Answer 1

In the industry of polymerisation,there is large no of monomers.so the problem is to store them safely because an uncontrolled spontaneous polymerisation of these monomer takes place with time takes place starting from free radicals.To avoid the degradation of monomer it is known to stabilize them by means of inhibiting substance which prevent polymerisation from takes place.The substance known as "polymerisation inhibitor".When it is desired to employ inhibited monomers in order to polymerise them,it is often necessary to remove the polymerisation inhibitor.For this adsorption is one of the best method and alumina is one of the best adsorbent.It adsorbed all the polymerisation inhibitor from the monomer in which these inhibitor placed in contact of alumina,and we get the monomer which can takes part in polymerisation reaction.
