Abstract
The invention relates to a method for enriching rosin acids from a hardwood-containing sulfate soap, in which the soap is partially acidified at a temperature higher than room temperature with an inorganic or organic acid so as to give the resulting mother liquid a pH of 4.5-7, thus enabling the rosin acids to be enriched from the soap into the fraction converted to the acid form, and the fatty acids to be enriched in the soap.
