Naphtha (petroleum), heavy catalytic cracked is a complex combination of hydrocarbons produced by a distillation of products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approximately 65.degree.C to 230.degree.C (149.degree.F to 446.degree.F). It contains a relatively large proportion of unsaturated hydrocarbons.

Extremelyflammable

The initial threshold screening level for naphtha, heavy catalytic cracked is 115 μg/m3 (annual averaging time).
