Dodecanoic Acid Lauric acid 143-07-7
1. Industrial production method can be summarized as two types: one is from natural plant oil saponification or decomposed under high temperature and high pressure; Isolated from the synthesis of fatty acids. Japan's main coconut oil and palm kernel oil as raw material for making lauric acid. Portion of twelve sour crude vegetable oils are: coconut oil, mountain pale nucleolus oil, palm kernel oil and mountain Hu Jiaoren oil etc. Other plants, such as palm kernel oil, brush tree seed oil, camphor tree seed oil can also services such as preparing twelve acid. More than twelve acid extracted by C12 fractions, contains a lot of twelve acid, can be in normal pressure hydrogenation, without catalyst, can turn hydrocarbon for twelve acid by more than 86% of the conversion.
2. Hydrolysis separation from coconut oil and other vegetable oil refining.
3. In glyceride form naturally in coconut oil, mountain pale nucleolus oil, palm kernel oil and Hu Jiaoren oil etc. Industry can be made of natural oils on hydrolysis. Will join the rest of the autoclave coconut oil, water, and the catalyst, hydrolysis under 250 ℃, about 5 mpa pressure into glycerol and fatty acids, including lauric acid was 45% ~ 80%, the distillation of lauric acid.
4. The method of palm kernel oil Malaysian palm oil production accounted for more than half the world's total output. The palm kernel oil is mainly composed of C6 ~ C18 fatty acids, usually lauric acid accounted for 46% ~ 51%.
5. Mountain pepper nucleoli oil method Mountain pepper lauraceae plants, is a kind of deciduous trees. Spicebush, having a globose drupe fruit green at first, for the black after maturity, mountain pepper nucleoli oil contains laurate in more than 30%. Other plants, such as palm kernel oil, sassafras seed oil, camphor tree seed oil can be used to prepare in lauric acid, etc.
6. Tobacco: OR, 44. FC, 41; OR, 26; FC, OR 18; FC, 15; BU, 26; FC, 40.
use
1. Used for resin, plasticizer, surface active agent, emulsifying agent and demulsifier of raw materials, can also be used as anti-freeze and heat carrier.
2. Used as gas chromatographic stationary liquid and solvent, antifreeze, plasticizer, and dehydrating agent.
