Question

Give the reaction of Urea with Ethanol​

Answer 1

Answer:

Reaction of urea with alcohol produces dialkyl carbonates in stepwise manner.

Explanation:

Urea alcoholysis i.e. reaction of urea with alcohol produces dialkyl carbonates in stepwise manner. In the first step urea reacts with alcohol and forms the corresponding alkyl carbamate (AC) and in the second step this alkyl carbamate reacts further with another molecule of alcohol to yield dialkyl carbonate.

Answer 2

Answer:

The urea in wines results from the metabolism of arginine or citrulline by yeast or other organisms. The urea waste product is initially metabolised inside the yeast cell until it builds up to a certain level. At that point, it is excreted externally where it is able to react with the alcohol to create ethyl carbamate.
