Decanoic acid is an important raw material for chemical production, which has a wide range of properties and uses. In this paper, the properties, production methods, uses and safety precautions of decanoic acid will be introduced in detail.

1. the properties of decanoic acid

decanoic acid is a saturated fatty acid with a chemical formula of C10H20O2 and a molecular weight of 172.26. It is a colorless or yellowish transparent liquid with a strong pungent odor. Capric acid is insoluble in water, but soluble in ethanol, ether, acetone and other organic solvents. It has a melting point of -3.5°C, a boiling point of 274°C and a density of 0.886g/cm3. Decanoic acid has good oxidation resistance and thermal stability, and can maintain stability under high temperature and aerobic conditions. The production method of

2. decanoic acid

decanoic acid can be obtained by hydrolysis and separation of natural oils and fats, and can also be prepared by chemical synthesis methods. Natural oil hydrolysis method is the reaction of oil and water under acidic or alkaline conditions to produce glycerol and fatty acids, and then decanoic acid is separated by distillation. Chemical synthesis is mainly through the alkene carboxylation reaction or esterification of capric acid preparation.

3. The use of decanoic acid

1. Plastic and rubber industry: decanoic acid can be used as a plasticizer in plastic and rubber products to improve the flexibility and processing performance of products.
2. Lubricating oil additives: capric acid can be used as lubricating oil additives to improve the oxidation resistance and wear resistance of lubricating oil.
3. perfume and daily chemical industry: decanoic acid can be used as a perfume in daily chemical products, giving the product a specific smell.
4. Pharmaceutical intermediates: decanoic acid can be used as pharmaceutical intermediates in the production of drugs.
Precautions for the safe use of
4. capric acid

1. Capric acid has a pungent odor and should be avoided for a long time.
2. In the process of using decanoic acid, attention should be paid to maintaining good ventilation and avoiding inhalation of vapor.
3. Decanoic acid should be stored in a cool, dry, well-ventilated place, away from fire and heat sources.
4. When transporting capric acid, special airtight containers should be used to avoid leakage and environmental pollution.

In conclusion, decanoic acid as an important raw material for chemical production has a wide range of properties and uses. In the process of use, attention should be paid to safe use to ensure production safety and personnel health.
