Question
Chapter 16, Problem 5Q
Interpretation Introduction
Interpretation:
The formation of diethylacetal of acetaldehyde as an impurity in the fermentation needs to be explained.
Concept Introduction:
Sucrose is used to prepare ethanol in the presence of invertase and zymase enzymes. Invertase enzyme involves in hydrolysis of sucrose molecule that results the formation of glucose and fructose molecules. Later the reaction of glucose and fructose in the presence of zymase enzyme converts the monosaccharides to ethanol and water. The process is called as fermentation.
The reaction is represented as follows:
