摘要：
The object of the invention is to reduce foaming of black liquor. It is based on observation about the effect of colloidal neutral substances on the separation of soap. According to the method foaming of the black liquor is reduced by adding stabilized colloidal neutral substances to the black liquor. The amount of colloidal neutral substances is enough to change most of the fatty acid soap and resin acid soap to liquid crystal phase.
