发明名称 Process for the preparation of esters of racemizable acids.
摘要 <p>The subject of the present invention is a process for the esterification of an ammonium carboxylate. This esterification of an ammonium carboxylate by an alcohol is characterised in that the reaction mixture is subjected to a reduced pressure, preferably to a reduced pressure of 10&lt;3&gt; to 10&lt;5&gt; Pascal, preferably of 10&lt;3&gt; to 5x10&lt;4&gt; Pa, upper limit not included. Application to organic synthesis.</p>
