Preparation of inorganic esters from alcohols
WebEsters, of inorganic acids The alcohol groups of unpleasant-tasting drugs are often converted to esters in order to mask the taste. In most cases, the ester has a less unpleasant taste than the free alcohol. The mechanisms of these reactions that form acid derivatives are covered with similar mechanisms in Chapter 21. Show the alcohol and the … WebThe first step of the mechanism is similar to the formation of nitrate esters that we saw in the previous video. OK. So this is going to be a reaction equilibrium. Or it's reversible. And …
