Properties and stability
1. It is a white solid at room temperature with an unpleasant odor. It is insoluble in water and soluble in ethanol and most organic solvents.
2.This product is non-toxic. The oral LC50 of mice is greater than 10g/kg, but it has a irritating effect on the skin.
3. Found in flue-cured tobacco leaves, burley tobacco leaves, and oriental tobacco leaves.
4. Naturally found in apples, beef, and wheat bread.
Storage method
Packed in aluminum drums, 100kg per drum. Store in a cool, ventilated and dry place, keep away from sources of fire and oxidants.
Synthesis method
1. Hydrolyze coconut oil, laurel oil, and Litsea cubeba oil to produce lauric acid, and at the same time capric acid is produced as a by-product, with a yield of 30% of lauric acid.
2. Tobacco: OR, 44, 49; BU, 56; OR, 26; FC, 9; FC, 15; FC, OR, 18; BU, 26; FC, 40. Prepared from octane bromide.
Purpose
1. Mainly used to prepare capric acid ester products. Its esters can be used as spices, wetting agents, plasticizers and food additives.
2.Mainly used as raw material for plastic plasticizers and cationic fungicides. Its fatty acid esters have a fruity aroma and are used as spices.
