Problems solved by technology

However, trialkylchlorosilanes are used in this method, and trialkylchlorosilanes are easily hydrolyzed to generate high-boiling compounds, which are difficult to remove from the reaction mixture, so this method is not suitable for industrial production

Abstract

The invention relates to a method for preparing stable iodized vegetable oil and iodized vegetable oil fatty acid ethyl ester, which includes the following steps: first, vegetable oil and iodized hydrogen gas are caused to take addition reaction so as to generate iodized vegetable oil; then, the unstably combined iodine in iodized vegetable oil is removed by heating and ventilating air method, and the removed free iodine is eliminated by using lopsidedness sulfite solution liquid sealing, thus getting the iodized vegetable oil with good stability; the stable iodized vegetable oil and ethanol are caused to take transesterification reaction under the effect of salt catalyst so as to generate the stable iodized vegetable oil fatty acid ethyl ester. The product prepared by the method for preparing stable iodized vegetable oil and iodized vegetable oil fatty acid ethyl ester has the advantages of low viscosity, good stability and low cost.

Description

technical field [0001] The invention relates to a preparation method of stable iodized vegetable oil and fatty acid ethyl ester of iodized vegetable oil. Background technique [0002] In 1901, Dr. Marcel Guerbet, a Frenchman, successfully developed iodized oil, which was only applied to the surface of human skin for disinfection. In 1918, by chance, iodized poppy seed oil (Lipiodol) was discovered to have radiopaque properties, making it the world's first iodine-containing contrast agent for X-rays. In 1923, the French Sicard and Forestier successfully used iodized poppy seed oil (Lipiodol) for intravenous injection contrast, and then iodized poppy seed oil (Lipiodol) began to be used in radiology, becoming the world's first medical iodized contrast agent. In 1926, Guerbet (Garbet) company was established in France. After the company was established, it mainly produced iodized poppy seed oil (Lipiodol). The city of Saint-Ouen (Sain Ouen) established Garber Laboratory, spe...
