Abstract
La presente invencion se relaciona a composiciones que comprenden mezclas de dos formas enantioméricas de anhídrido diaciltartárico y mezclas obtenidas reaccionando un compuesto orgánico con una mezcla que comprende dos formas enantioméricas de anhídrido diaciltartárico. La invencion se relaciona también a un método pata la preparacion de tales mezclas enantioméricas, iniciando a partir de una mezcla que comprende ácido D-tartárico y ácido. El método implica reaccionarácido tartárico con anhídrido de ácido graso bajo condiciones de calentamiento dieléctrico.
