Usage

General Description

A white chalky solid. Softens at 162°F.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

FireMaster FF 1. is relatively inert . These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions.

Fire Hazard

Flash point data for FireMaster FF 1. are not available; however, FireMaster FF 1. is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and teratogenic data. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of Br-. See also POLYBROhIINATED BIPHENYLS.

Mechanism of PCBs formation from the pyrolysis of chlorobenzenes

Polychlorinated biphenyls (PCBs) were formed by pyrolysis of chlorobenzenes in a HCl atmosphere. Varieties of substituted chlorobenzenes were used as model compounds to optimize the condensation reaction. Lower chlorinated benzenes produce more PCBs than that of higher ones. Up to 0.7 μg PCBs/mg 1,2,3-trichlorobenzene was produced through the condensation reaction.

The effect of oils on PAH, PCDD, PCDF, and PCB emissions from a spark engine fueled with leaded gasoline

The effect of synthetic and mineral oils on the formation of polyaromatic hydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs) in emissions from a spark ignition engine was studied on a Skoda Favorit engine fueled with leaded gasoline. The test cycle simulated urban traffic conditions on a chassis dynamometer, in accordance with the ECC 83.00 test. The data for selected PAHs as well as PCDDs, PCDFs, and PCBs congener profiles are presented. PCDD/Fs emissions for an unused oil and the oil after 10 000-km operation varied from 300 to 2000 fmol/m3, PCBs emissions from 75 to 178 pmol/m3, and PAHs emissions from 150 to 420 μg/m3. The content of PCBs in oils varied from 2 to 920 mg/kg.
