Abstract

1,052,976. Neutralizing raw detergents. MARCHON PRODUCTS Ltd. Aug. 11, 1965 [Aug. 27, 1964], No. 35125/64. Heading C2C. A process for the continuous neutralization of sulphated or sulphonated detergent raw materials comprises reacting the said materials with an alkali in a mixer, which mixer comprises: a hollow stator member having an internal surface provided with a helical thread and enclosing a co-operating rotor member which is provided with an external helical thread of opposite hand to that on the stator member and not intermeshing therewith, the envelopes of the crowns of the helical threads defining two frusto-conical surfaces having a clearance between them and the depths of the threads varying in opposite senses between a maximum at one end and a minimum at the other end; said stator member being provided with an inlet for reactants at the basal portion of the frusto-conical surfaces, an outlet for the reaction products at the narrow end of the frustoconical surfaces, and means for rotating the rotor relatively to the stator about their common axis. In a preferred embodiment the pitch of the rotor thread is 50% greater than that on the stator, and the minimum pitch depth is zero. The preferred alkalis are NaOH, Na 2 CO 3 or KOH, used between 40-90‹ C., to neutralize sulphonated alkaryl hydrocarbons to which a small quantity of water has been added to stabilize the sulphonated hydrocarbon. The said raw materials are preferably derived by the process of Specifications 969,516 and 969,517. Especially suitable mixers are described in Specifications 842,692 and 882,517.
