Storage method

Storage Precautions[14] Store in a cool, ventilated warehouse. The temperature should not exceed 37°C. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, reducing agents, acids and alkalis, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency response equipment and suitable containment materials.

Synthesis method

Ethyl hexanoate naturally exists in pineapples and other fruits. It is industrially obtained by esterification of hexanoic acid and ethanol, followed by washing, neutralization and drying.

Purpose

1. It is used as a variety of blending spices, flavoring essences, fruit flavors, and also has great use in the flavoring of wine. Used as organic solvents and in organic synthesis.

2. Ethyl hexanoate is an edible flavoring that is allowed to be used according to my country’s hygienic standards for the use of food additives. It is often used to prepare fruity flavorings such as apples, pineapples, and bananas, and alcoholic flavors such as brandy and liquor. The dosage is based on normal production needs. Generally, it is 32mg/kg in chewing gum; 12mg/kg in candies and baked goods; and 7mg/kg in cold drinks.

3. It plays the role of top fragrance in floral and fruity daily flavors. It is often used to prepare food flavors such as bananas, pineapples, and apples, as well as flavors for brandy and liquor. The dosage in candies and baked goods is 12×10-6, and the dosage in chewing gum is 32×10-6.

4. Used in organic synthesis and preparation of artificial flavors. [15]
