  • Patent number: 3979470
    Abstract: Primary normal monochloroparaffins are produced in high yields in a chlorination process of normal paraffins by the recycling technique of the present invention. By the recycling of secondary and nonprimary monochloroparaffin to the chlorination zone and the treatment of the polychlorinated compounds formed in the chlorination to form the primary normal monochloroparaffins and a recycle stream of paraffin and nonprimary monochloroparaffin, normal paraffins may be converted essentially completely to the desired primary normal monochloroparaffins. In a specific aspect of the present invention, alpha, omega-dichloroparaffins may be recovered if desired.
