purpose
Food flavor: According to the Chinese national standard GB 2760, folate caproate is a permitted food flavor, which is commonly used to mix essence such as apple, berry, mango, passion fruit (passion fruit), tropical fruit, etc. The addition amount refers to the FEMA standard (such as soft drinks ≤ 0.5 mg/kg, candy, baked goods ≤ 3.0 mg/kg)
Other applications: naturally found in pineapple, apple, pear, strawberry, green tea, orange peel and other animals and plants, also used in tobacco and daily chemical essence
==============================================================================
synthetic route
Main method: Esterification reaction between cis-3-hexenol (CAS: 928-96-1) and n-hexanoic acid (CAS: 142-62-1) catalyzed by strong acidic cation exchange resin to obtain
Reaction equation:
Cis-3-hexenol+n-hexanoic acid → hexanoic acid leaf alcohol ester+water
Yield: Literature reports that the yield can reach about 88%
Industrial production: azeotropic dehydration method is often used to improve conversion rate, and the catalyst can be recycled, which is in line with the trend of green chemistry
