Abstract

The invention relates to a preparation method of phosphatidic acid sodium, which belongs to the technical field of fine chemical engineering. The preparation method is characterized in that soybean phosphatidic acid, rapeseed phosphatidic acid and cotton seed phosphatidic acid are adopted as raw materials, the phosphatidic acid is dissolved in a certain amount of normal butanol, a phosphatidic acid solution is heated to a certain temperature, a 95% ethanol solution of sodium hydroxide is added while the solution is stirred to obtain phosphatidic acid sodium precipitates. The precipitates are washed by 95% ethanol for two times and then dried to obtain a phosphatidic acid sodium product.

Description

technical field [0001] A preparation method of sodium phosphatidic acid belongs to the technical field of fine chemicals. [0002] technical background [0003] Sodium phosphatidic acid is an important surfactant, which can be used in the fine chemical industry and biomedicine, and also has important uses in the recent liposome research field. my country is a big producer and consumer of soybean oil, as well as a big producer of phospholipids. In 2012, my country's annual output of soybean oil reached 11.7 million tons, and its by-products can obtain about 50,000 tons of phospholipid products. Adding rapeseed phospholipid and cottonseed phospholipid, the potential phospholipid output reaches about 150,000 tons. Among these phospholipids, only soybean phospholipids have been well developed and utilized, while most of rapeseed phospholipids and cottonseed phospholipids have not been effectively developed and utilized. One of the processed products of these phospholipids is p...
