Improved process for the liquid phase chlorination of C{HD 8{B {14 C{HD 16 {B paraffin hydrocarbons

摘要

An improved process for the liquid phase chlorination of a C8 to C16 paraffin hydrocarbon mixture is provided which is capable of yielding a product of enhanced quality through the elimination of an undesirable side reaction in the gaseous mixture which is in contact with the liquid mass where the desired chlorination reaction is carried out. A minor quantity of an additive (e.g. carbon tetrachloride) is provided in the reaction zone and is at least partially present in the gaseous mixture where an undesirable reaction between paraffin hydrocarbon vapor and gaseous chlorine is eliminated. Not only is the product color improved, but the liquid phase chlorination reaction has been found to proceed at a more rapid rate.
