Process for the handling of dialkyl sulphosuccinates |
abstract |
C4-C16 dialkyl sulphosuccinates are prepared as 30-50% by weight aqueous compositions at reaction temperatures above 85 DEG C. In order to prevent a sudden large viscosity rise on cooling below 75 DEG C, urea (10 to 30% by weight based on the dialkyl sulphosuccinate) is added to the reaction mixture as it cools. |
