Answer  Explanation 

ANSWER: N-Butyl Alcohol

Explanation:

  • Chemical used in fermentation of sugar is N-Butanol or Normal Butanol, or N-Butyl Alcohol.
  • n-Butanol occurs naturally as a minor product of the fermentation of sugars and other carbohydrates, and is present in many foods and beverages.
  • It is also a permitted artificial flavorant in the United States, used in butter, cream, fruit, rum, whiskey, ice cream and ices, candy, baked goods and cordials.
  • It is also used in a wide range of consumer products.
  • The largest use of n-butanol is as an industrial intermediate, particularly for the manufacture of butyl acetate (itself an artificial flavorant and industrial solvent).
