Abstract
Procedimiento para la obtención de ésteres de ácidos mono- o dicarboxílicos con alcoholes alifáticos y sulfato amónico, caracterizado porque amidas de ácidos carboxílicos alifáticos o aromáticos se hacen reaccionar con alcoholes, ácido sulfúrico y/o bisulfato amónico a temperatura más elevada, empleándose, por equivalente de amida de ácido, 0,3 hasta 0,6 moles de ácido sulfúrico a 0,6 hasta 1,2 moles de bisulfato amónico y 1 hasta 6 moles de alcohol.
