production method | preparation of crude drug ethyl linoleate crude product preparation soybean oil or sunflower oil is used as raw materials, ethanol and concentrated sulfuric acid are added, and the mixed fatty acid ethyl ester is prepared by lipid reaction. Add urea to produce crude ethyl linoleate. Soybean oil or sunflower oil [ethanol, concentrated H2SO4]→ mixed fatty acid ethyl ester [urea] → preparation of crude ethyl linoleate crude ethyl linoleate finished product The crude ethyl linoleate was distilled under reduced pressure to collect the 195 ℃/0.933kPa fraction, I .e. the finished ethyl linoleate. Crude ethyl linoleate [195 ℃, 0.933kpa]→ Preparation of ethyl linoleate finished product Lipping Take ethyl linoleate, soybean lecithin, and vitamin E to mix well according to the prescription ratio, and take vitamin C, Vitamin B6, hesperidin, inositol, calcium dexpantothenate, and nicotinic acid are pressed into a core, and then the ethyl linoleate mixture is added into a core to make a capsule. |
