Title:
PRODUCTION OF HIGHER ALCOHOL SULFURIC ACID ESTER SALT OF HIGH PURITY
Document Type and Number:
Japanese Patent JPS61277661
Kind Code:
A
Abstract:
PURPOSE: To obtain a compound useful as a surfactant in high purity and yield, by sulfating a higher alcohol with a specific moisture content or below with a specified amount of SO3, neutralizing the sulfate and spray-drying the resultant neutralized slurry.
CONSTITUTION: A higher alcohol with ≤0.1wt% moisture content, e.g. 12W14C saturated alcohol, is sulfated with 0.9W0.98mol, based on one mol above- mentioned alcohol, SO3. The resultant sulfate is then neutralized with caustic soda to form a slurry, which is spray-dried to remove water therefrom and afford the aimed substance higher alcohol sulfuric acid ester salt.
