| Physical and Chemical Properties | Physical and chemical properties tall oil fatty acid is a low cost unsaturated fatty acid (oleic acid), is a mixture of oleic acid, linoleic acid and its isomers. Insoluble in water, soluble in ether, ethanol; Can react with alkali, can also occur alcoholization, ammonia (amine) reaction. Its low boiling point characteristics are mainly used in the field of synthetic lubricating oil production. |
| Use | Tall oil fatty acids are mainly used for the preparation of oilfield chemicals and Ore flotation agents. It is also used in the production of dimeric and trimeric fatty acids for use in the coating industry. |

Abstract:
The present invention discloses a tall oil fatty acid imidazoline sulfonate surfactant, the main component of which has the following structural formula: wherein R is tall oil fatty acid alkyl. The tall oil fatty acid imidazoline sulfonate surfactant intermediate diamide prepared by the invention has less content, the tall oil fatty acid conversion rate is more than or equal to 98.5%, the product has low stimulation, the biodegradability in 7 days is 100%, and the atom utilization rate is high, high alkali resistance and acid resistance, good appearance and stability, excellent wax removal and corrosion inhibition effect, and excellent emulsification and oil stripping ability for mineral oil such as punching oil, rust prevention oil and cutting oil, it provides a new route for the deep processing of tall oil products in China, which can greatly improve the utilization rate of tall oil products, improve the added value of products, and have significant economic and social benefits.
Abstract:
The Waterborne Alkyd resin was synthesized by tall oil fatty acid. The optimized formula of waterborne alkyd resin was obtained by investigating the use of different fatty acids, neutralizing agent and cosolvent. The formula shows that tall oil fatty acid modified alkyd resin is superior to soybean oil fatty acid modified alkyd resin in drying time, weather resistance, hardness and other properties.

Abstract:
with tall oil fatty acid as raw material, stearic acid and unsaturated fatty acid were separated by low temperature gradient freezing crystallization, and then separated by high speed centrifugation, and the higher purity of oleic acid, linoleic acid and other unsaturated fatty acids were obtained. The method can realize the scale production and continuous operation, and the product yield can reach 90% ~ 95%.
