Description

colourless or white crystals There are three isomeric forms of dichlorobenzene (DCB): m-DCB is a flammable liquid and vapor.ChEBI: A dichlorobenzene carrying chloro groups at positions 1 and 4. dichlorobenzene: Any one of threeisomeric liquid aromatic compounds,C6H4Cl2. 1,2-Dichlorobenzene (b.p.179°C) and 1,4-dichlorobenzene (b.p.174°C) are made by chlorinatingbenzene with an iron catalyst andseparating the mixed isomers byfractional distillation; 1,3-dichlorobenzene(b.p. 172°C) is made fromon
