Properties and stability
1. Found in flue-cured tobacco leaves, burley tobacco leaves, and oriental tobacco leaves.
Storage method
Store airtight at room temperature. Storage temperature 2~8ºC
Synthesis method
1. Brief description of production method: obtained by esterification of myristate and methanol. Mix 2kg tetradecanoic acid and 3L methanol, add 200ml sulfuric acid, and heat to reflux for 10h. After recovering excess methanol, pour the reactant into cold water to wash away the acidity, then wash with 10% sodium carbonate and water in sequence, and distill under reduced pressure to obtain approximately 1.5kg of finished product.
2. Tobacco: BU, 56; OR, 57; FC, 9, 18; FC, 40.
Purpose
It is used in food flavors such as honey and coconut, as well as in daily flavors. It is also used in organic synthesis, gas chromatography and biochemical research.
