Properties and stability
1. Use and store according to specifications. It will not decompose and avoid contact with oxides.
2. Found in flue-cured tobacco leaves.
Storage method
Should be sealed and stored at 4℃.
Synthesis method
1. Found in a variety of plant waxes (such as candelilla wax). Can react with alkali. Esterification and ammonia (amine) reactions can also occur. Prepared by oxidation of triacontanol. In addition, a small amount of triacontanic acid exists in the waxes of some plants and insects and in montan wax, which can be extracted using appropriate techniques.
2. Tobacco: FC, 15, 41.
3. Obtain phosphorus or needle crystals from ethanol or acetone.
Purpose
Used for biochemical research and special organic synthesis.
