In chemistry , the diisopropylbenzenes form a group of substances whose structure consists of a benzene ring with two isopropyl groups  (–CH (CH 3 ) 2 ) as substituents . Their different arrangement results in three constitutional isomers with the empirical formula C 12 H 18 .

properties

The boiling points of the diisopropylbenzenes are almost the same. The melting points differ more clearly. The 1,4-diisopropylbenzene, which has the highest symmetry, has the highest melting point.
