PROCESS OF OBTAINING MIXTURE OF HIGHER FATTY ACIDS Russian patent published in 2008 - IPC C11C1/04 C11C1/10 C07C57/12 

FIELD: chemistry, organic, fatty acids.

SUBSTANCE: invention relates to process of obtaining mixture of higher fatty acids that are widely used in chemical, petrochemical, varnish-and-paint, tyre and other industry branches. The process involves isolation of fatty acids from the fat raw material with their subsequent distillation. Fatty acids, at that, will be released from sunflower oil by means of its distillation at the temperature 230-260°C and residual pressure 0.13-0.8 kPa, the distillate thus obtained will be repeatedly subjected to distillation at the temperature 210-220°C and residual pressure 0.67-1.33 kPa. The process enables one to reduce 2.5-5-fold unit discharge of the oil for production of distilled fatty acids, to simplify technology of obtaining distilled fatty acids and improve quality of the distilled fatty acids.

EFFECT: simplification of technology of obtaining and improvement of quality of distilled fatty acids.
