hydrocarbon

[hi″dro-kahr´bon]

an organic compound that contains carbon and hydrogen only.

alicyclic hydrocarbon one that has cyclic structure and aliphatic properties.

aliphatic hydrocarbon one in which no carbon atoms are joined to form a ring.

aromatic hydrocarbon one that has cyclic structure and a closed conjugated system of double bonds.

chlorinated hydrocarbon any hydrocarbon compound with chlorine substitutions; many are toxic. They are used mainly as refrigerants, industrial solvents, dry cleaning fluids, and insecticides (such as ddt and dieldrin). Some have been used as anesthetics, such as chloroform.

chlorinated hydrocarbon

a HYDROCARBON containing chlorine, such as the insecticide DDT (dichlorodiphenyltrichloroethane). These compounds persist in the environment and can accumulate in various ANIMALS and in FOOD CHAINS. Such properties have restricted the use of the compounds.

Many shops use spot cleaning products that contain very high concentrations of chlorinated hydrocarbons. When chlorine-free dry cleaning solvents like DF-2000 are used, these products increase the probability that the waste streams will fail regulatory benchmarks.
