Electrical properties of "water in castor oil" emulsion

Abstract

Castor oil belongs to the group of nondrying oils, it is very viscous, weakly dissolved in gasoline and other organic solvents, does not freeze at low temperatures (minus 12-18 °C), flames up at high temperatures (plus 300-310 °C). That is why it is an unsurpassed lubricant when it comes to quality, especially for aviation engines and mechanisms operating under complicated conditions of the north. The oil is obtained from castor seeds by hot or cold pressing. Hot pressing ensures greater yield of oil, but its quality is worse, because poisonous substances, such as ricin and ricinin, get to the oil from seeds. That is why this oil is suitable only for technical needs. To obtain a high-quality product, the oil is to be purified. Existing traditional purification methods (filtration, settling, etc.) do not make it possible to get a high-quality product or are energy-and resource-consuming. That is why it is urgent to find new technologies for castor oil purification from plant impurities, which would allow reducing the cost of production and improving product quality.
