AB  - Dimethyldicarbonate (DMDC) is a sterilant proposed for use on wine immediately before bottling for the prevention of fermentation by yeast. The major breakdown products of DMDC in wine are carbon dioxide and methanol, primarily from hydrolysis. Earlier work has shown DMDC to react with ethanol and ammonia to form small amounts of residual by-products. Other by-products are expected. This study investigates the reaction of DMDC with higher alcohols. Work was done in model solution with n-propyl, isobutyl, isoamyl, active amyl, n-hexyl, and phenethyl alcohols. Product formation is linear with substrate concentrations. Predicted amounts of by-product formation in wine are in the low-micrograms-per-liter range.
