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.

Tall Soap - Undesirable Waste at Paper Production or Valuable Raw Material?
Rousková, Milena ; Tříska, Jan ; Heyberger, Aleš
The paper and pulp industry is due to its huge production capacity source of a big amount of waste - tall soap. This material is often utilized as a not very valuable source of energy, even though it contains many compounds applicable in the chemical, pharmaceutical, food or cosmetics industry. It comprises of a high proportion of fatty and resin acids, used as additives to grease, adhesives, resins, paints or inks. Long-chain aliphatic alcohols serve medical purposes, mainly for atherosclerosis treatment. Phytosterols belong to the most valuable substances contained in the tall soap. These compounds are being applied for hypercholesterolaemia and some types of cancer, they also have a significant therapeutic effect on the cardiovascular and immune systems. Waste tall soap is potentially a very valuable source of a broad spectrum of substances.
