Use

The fungicides, chlozolinate, vinclozolin, and procymidone, are added to wine after fermentation and the degradation products are isolated and identified. Chlozolinate undergoes a rapid hydrolytic loss of the ethoxycarbonyl substituent to give an oxazolidine that further undergoes hydrolytic cleavage to give 3' ,5' -dichloro-2-hydroxypropanilide. The oxazolidine ring of vinclozolin undergoes a similar hydrolysis reaction to give the corresponding anilide, 3' ,5'-dichloro-2-hydroxy-2-methylbut-3-eneanilide. Both of these anilides are stable in wine for 150 days. A different degradation behavior is observed with procymidone and leads to the formation of 3,5- dichloroaniline, which, in turn, breaks down in wine.
