Properties and stability
Use and store according to specifications. It will not decompose and avoid contact with oxides.
Colorless liquid. It has the fruity aroma of ripe fruit, is mellow and sweet, but has a spicy taste, and is found in a variety of foods.
Storage method
This product should be sealed and stored in a cool, dry place.
Synthesis method
1. Use n-hexanoic acid and amyl alcohol to catalyze esterification in the presence of p-toluene sulfon and acid. During the reaction, benzene is added as a water entrainer to obtain it through azeotropic reflux dehydration and condensation.
2.Prepared by reacting n-hexanoic acid and pentanol in the presence of p-toluenesulfonic acid.
Purpose
1. Formulate fruity flavors such as pineapple, mango, banana and other fruity flavors to sweeten and modify the aroma of wine. It can also serve as an auxiliary solvent in the application of daily chemical fragrances.
2.Used in the formulation of edible and daily chemical fragrances. Used to prepare fruity flavors, such as pineapple, mango, banana and other fruity flavors.
