The object of research is
Technology of fatty acids production from soapstock with the use of sulfuric acid decomposition.
The aim of research is to
Dependence of the yield and the neutralization number of fatty acids on the soapstock treatment.
Rational conditions of fatty acids obtaining by soapstock treatment with sulfuric acid.
Oil and fat industry waste, alkaline neutralization, soapstock, fatty acids, sunflower oil.
Main scientific results imply the following
Regression dependences was established of the yield and the neutralization number of fatty acids on the processing conditions of soapstock: temperature and duration.
Scope of application
It will make it possible to obtain high quality fatty acids in industrial conditions and predict the yield and neutralization number of fatty acids.
Limitations for practical use
The resulting fatty acids must be washed from sulfuric acid residues and checked for the presence of sulfate ions with the calcium chloride solution.
