Abstract:

Fatty acids are an important component in the pharmaceutical, food, chemical industries. The production of various types of products requires a certain purity and quality of fatty acids. To obtain these compounds, it is promising to use soapstocks, which are waste products of alkaline refining of oils. The peculiarity of the work lies in determining the effect of the process parameters of soapstock decomposition with sulfuric acid on the saponification number, which is an important production characteristic of fatty acids. The study used sunflower soapstock according to DSTU 5033 (CAS 68952-95

Abstract:

As a result of alkaline neutralization of oils, a significant amount of soapstock is formed, the utilization of which creates an environmental and economic problem. The production of fatty acids from soapstock using sulfuric acid decomposition is investigated in this work. The peculiarity of the work is the determination of regression dependences of the yield and neutralization number of fatty acids on the soapstock processing conditions: temperature and duration. Soapstock obtained after neutralization of sunflower oil was used as raw material. Soapstock indicators: mass fraction of moisture

Abstract:

The object of the study is the process of esterification of sunflower soapstock fatty acids with butanol. Soapstock is a waste of the oil and fat industry, which is formed in the process of alkaline neutralization of oils. The processing of soapstock to obtain fatty acids is promising, since the disposal of waste is difficult and dangerous, and fatty acids are an industrially valuable product. Fatty acids obtained from soapstock are an available raw material for the production of fatty acid esters of low molecular weight alcohols, which are the basis of alternative biodiesel fuel. The influenc

Abstract:

From soapstock, which is a waste product of sunflower oil production, the fatty component was isolated using isopropyl alcohol, toluene, fusel oil and a mixture of common salt and nonionic surfactants. With the help of the Langmuir film balance the molecular areas of isolated fats were found and the degree of hydrophobization in comparison with the original soapstock was evaluated. It was found that the strongest compression of the monolayer is observed when using fusel oil. The surface active properties of emulsifiers, synthesized by alkaline hydrolysis method on the basis of the obtained fat

Abstract:

Soapstock is a large-tonnage waste of the oil and fat industry, the disposal of which is environmentally hazardous. Processing of soapstock into industrially valuable products, in particular, fatty acids, is promising. The method for producing fatty acids, which consists in sequential saponification of soapstock with sodium hydroxide solution, salting out with sodium chloride and decomposition with sulfuric acid solution has been investigated. The feature of this work is the study of the effect of salting out conditions of saponified soapstock on the yield and neutralization number of fatty ac
