一种稳定的碘化植物油、碘化植物油脂肪酸乙酯的制备方法
摘要：
本发明涉及一种稳定的碘化植物油、碘化植物油脂肪酸乙酯的制备方法。本发明先将植物油与碘化氢气体发生加成反应生成碘化植物油，然后用加热和通空气的方法脱去碘化植物油中结合不稳定的碘，并以偏重亚硫酸钠溶液液封除去脱下的游离碘，得到具有良好稳定性的碘化植物油，该稳定的碘化植物油再在盐类催化剂作用下与乙醇进行酯交换反应，生成稳定的碘化植物油脂肪酸乙酯。该方法制备的产品具有粘度小、稳定性好、成本低的特点。
摘要（英）：

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.
