![**Ethyl Butyrate Production and Calculation**
Ethyl butyrate, \( \text{CH}_3\text{CH}_2\text{CH}_2\text{CO}_2\text{CH}_2\text{CH}_3 \), is an artificial fruit flavor commonly used in the food industry, particularly in flavors like orange and pineapple. It gives off a fragrance and taste that are typically associated with fresh orange juice, making it a popular choice as an orange flavoring agent.
### Chemical Reaction
Ethyl butyrate can be synthesized through the reaction of butanoic acid with ethanol in the presence of an acid catalyst \( (\text{H}^+) \):
\[
\text{CH}_3\text{CH}_2\text{CH}_2\text{CO}_2\text{H}(\text{l}) + \text{CH}_2\text{CH}_3\text{OH}(\text{l}) \xrightleftharpoons{\text{H}^+} \text{CH}_3\text{CH}_2\text{CH}_2\text{CO}_2\text{CH}_2\text{CH}_3(\text{l}) + \text{H}_2\text{O}(\text{l})
\]
