dichlorobenzene

Chemistry

Any one of three isomeric liquid aromatic compounds, C₆H₄Cl₂. 1,2-Dichlorobenzene (b.p. 179°C) and 1,4-dichlorobenzene (b.p. 174°C) are made by chlorinating benzene with an iron catalyst and separating the mixed isomers by fractional distillation; 1,3-dichlorobenzene (b.p. 172°C) is made from one of the other two by catalytic isomerization. The 1,2 isomer is used as an insecticide and in making dyes; the 1,4 compound is employed as a deodorant and moth repellent.
