Claims

1. IN A PROCESS FOR PRODUCING NEUTRAL SULFATED ALKOXYLATED ALKYL PHENOLS WHICH CONSISTS ESSENTIALLY OF REACTING LIQUID CHLOROSULFONIC ACID WITH A LIQUID ALKOXYLATED ALKYL PHENOL AND SUBSEQUENTLY NEUTRALIZING, THE IMPROVEMENT WHICH COMPRISES, IN COMBINATION, THE STEPS OF SUBJECTING THE SAID LIQUID MATERIALS TO CENTRIFUGAL FORCE AT SUPERATMOSPHERIC PRESSURE IN A ZONE OF ENERGETIC SHEARING FOR QUICKLY AND INTIMATELY MIXING SAID LIQUIDS WITH AN ENERGY OF AT LEAST 2.5 WATTS PER GRAM PER MINUTE AND FOR A TIME PERIOD NOT EXCEEDING 1 SECOND, FORCING THE MIXTURE PROMPTLY FROM THE SHEARING ZONE INTO A RELATIVELY UNPRESSURED REACTION ZONE TO PRODUCE A LIQUID REACTION PRODUCT AND A GASEOUS BY-PRODUCT, VENTING THE GASEOUS BYPRODUCT AND RECOVERING A SUBSTANTIALLY DEGASIFIED LIQUID SULFATED ALKOXYLATED ALKYL PHENOL.
