其他详情（用途，包装）：
Lauric acid, also known as dodecanoic acid, is a saturated fatty acid. Its molecular formula is C12H24O2. Although named lauric acid, it only accounts for 1-3% of the content in bay oil. At present, it has been found that vegetable oils with high content of lauric acid include coconut oil 45-52%, palm kernel oil 44-52%, babassu kernel oil 43-44%, etc. Lauric acid belongs to saturated fatty acids.

Storage method
1. Cover with a plastic bag and wrap in a burlap bag. Store in a cool, ventilated, and dry place. Keep away from heat and fire sources, moisture and sun protection.
Preparation method
1. Industrial production methods can be classified into two categories: one is obtained from natural plant oils through saponification or decomposition under high temperature and high pressure; The second is to separate from synthetic fatty acids. Japan mainly produces lauric acid from coconut oil and palm kernel oil as raw materials. The natural vegetable oils used to produce dodecanoic acid include coconut oil, hawthorn kernel oil, palm kernel oil, and mountain pepper kernel oil. Other plants such as palm kernel oil, tree seed oil, camphor tree seed oil, etc. can also be used to produce dodecanoic acid in the service industry. The remaining C12 fraction from the extraction of dodecanoic acid contains a large amount of dodecenoic acid, which can be hydrogenated at atmospheric pressure without the need for catalysts and can be converted to dodecanoic acid with a conversion rate of over 86%.
2. It is obtained by separating and refining coconut oil and other vegetable oils after hydrolysis.
3. It naturally exists in the form of glycerides in coconut oil, hawthorn kernel oil, palm kernel oil, and pepper kernel oil. It can be obtained from the hydrolysis of natural oils and fats in industry. Coconut oil, water, and catalyst are added to an autoclave and hydrolyzed at 250 ℃ and a pressure of about 5MPa to form glycerol and fatty acids, which contain 45% to 80% dodecanoic acid. After distillation, dodecanoic acid is obtained.
4. Palm kernel oil production in Malaysia accounts for over half of the world's total palm oil production. Palm kernel oil is mainly composed of fatty acids ranging from C6 to C18, with lauric acid typically accounting for 46% to 51%.
5. Pepper kernel oil method. Pepper belongs to the Lauraceae family and is a deciduous tree. The stone fruit of mountain pepper is spherical in shape, initially green in color and black when ripe. The kernel oil of mountain pepper contains more than 30% lauric acid.
Other plants such as palm kernel oil, sassafras seed oil, camphor seed oil, etc. can also be used to produce lauric acid.
Product Usage
1. Mainly used as raw materials for the production of alkyd resins, wetting agents, detergents, insecticides, surfactants, food additives, and cosmetics. This product is often used as a lubricant and has multiple functions such as lubricant and vulcanizing agent. However, due to its corrosive effect on metals, it is generally not used for plastic products such as wires and cables. This product is widely used in the surfactant industry and can also be used in the fragrance and pharmaceutical industries.
2. Used as a surface treatment agent for preparing adhesives. It is also used in the manufacture of alkyd resins, chemical fiber oils, insecticides, synthetic fragrances, plastic stabilizers, and corrosion-resistant additives for gasoline and lubricants. Widely used in the manufacture of various types of surfactants, such as cationic types such as laurylamine, lauronitrile, trimethoprim, cinnamyl dimethylamine, and cinnamyl trimethylammonium salt; Anionic types include sodium lauroyl sulfate, lauric acid sulfate ester, and triethanolammonium lauroyl sulfate; The zwitterionic types include laurel betaine, imidazoline lauric acid, etc; Non ionic surfactants include poly (L-ol) monolauric acid ester, polyoxyethylene lauric acid ester, glycerol lauric acid ester polyoxyethylene ether, and diethanolamide lauric acid. In addition, it is also used as a food additive and in the manufacture of cosmetics.
3. Lauric acid is a raw material used in the production of soap, detergents, cosmetic surfactants, and chemical fiber oils.
