  • Preparation of linear alkylbenzenes
    Patent number: 4216345
    Abstract: Process for the preparation of alkylbenzenes by partial chlorination of linear C.sub.9 -C.sub.15 paraffins, catalytic alkylation of benzene with the resulting mixture and fractionation by distillation of the alkylation products.At least a part of the unreacted paraffins recovered by fractionation and to be recycled to the chlorination stage is submitted, continuously or intermittently, to a purification treatment with molecular sieves.The content in undesired by-products of the alkylbenzenes can thus be maintained at negligibly low values.

  • Process for chlorinating linear paraffins
    Patent number: 4100212
    Abstract: Liquid-phase chlorination of n-paraffins is improved as to yield on chlorine and as to restriction to mono-substitution by passing the paraffins up a reactor divided into stages by baffles and feeding chlorine in controlled amounts to each stage.
