Tall soap is most frequently used as an alternative low quality fuel in the paper mills. But after conversion to tall oil (by acidification with sulphuric, hydrochloric or phosphoric acids) it could be processed by extraction separation of fatty and resin acids and neutral compounds, especially phytosterols and/or long-chain aliphatic alcohols. The aim of this study was the investigation of the tall soap liquid-liquid extraction by hexane and the study of the different parameters, especially pH value on the yield of sterols, fatty acids and resin acids.

Extraction of Phytosterols from Tall Soap Using a Selected Organic Solvents
Rousková, Milena ; Heyberger, Aleš ; Volaufová, Eva ; Tříska, Jan ; Krtička, M.
The contribution is focused on the extraction separation of the neutral part from tall soap from the paper mill Mondi Business Paper SCP, s.c. Ružomberok (Slovak republic). Dependences of the total amount of extracted phytosterols and ß-sitosterol on the applied extraction agent were studied. Hexanol, isobutanol, methyl isobutyl ketone, butyl acetate, limonene and hexane were tested. Yields of sterols with the regard to the type of deemulsifier used in the extracted system were compared as well. Acidity of the feeded tall soap-water-deemulsifier, modified by sulphuric acid addition before neutral components extraction, was analyzed as a further parameter. Study of the influence of elevated temperature on the extraction efficiency, was also one part of the work.
