Application

1. Food additives It has a fruity aroma similar to that of apples and pears and is often used to prepare food flavors such as baking, beverages, candies, wine, cakes, etc.

2. Spices and flavors It is used in cosmetics, perfumes, detergents, etc. to provide a fresh aroma.

3. Solvents As an excellent solvent in organic synthesis, it is widely used to dissolve resins, paints and lipids, especially suitable for the production process of the coating and ink industry. Its low volatility and good solubility enable it to play a stable role during the reaction process.

4. As a core solvent, it is used to prepare resins and pigments, improve the adhesion, weather resistance and glossiness of the coating, and is used in construction, automobiles and other fields.

5. Cleaning agents It is used to clean electronic or precision instruments and can effectively remove grease and resin substances.

6. Produce plastic polypropyl propionate.

7. Used as lubricant additives.
