Abstract of EP 0517571  (A1)
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<3> to 10<5> Pascal, preferably of 10<3> to 5x10<4> Pa, upper limit not included. Application to organic synthesis.
