Distillation of chloroxylenes |
| 摘要 |
Mono-chloroxylene is separated from the product of side chain chlorination of xylene by distillation under reduced pressure from that product to leave a still residue having an increased proportion of xylene dichloride. The distillation is carried out on a mixture of the chlorination product and an aliphatic amine which sequesters iron, preferably triethylamine.
