Abstract
La presente invención se refiere a un proceso para preparar un éster de un éter de celulosa que comprende las etapas de hacer reaccionar un éter de celulosa con un anhídrido de ácido dicarboxílico o con una combinación de un anhídrido de ácido dicarboxílico y un anhídrido de ácido monocarboxílico alifático, en donde la esterificación se realiza i) en la ausencia de un catalizador de esterificación o en la presencia de no más de 0.1 mol de un catalizador de esterificación por mol de unidades de anhidroglucosa de éter de celulosa, y ii) en la presencia de un ácido carboxílico alifático, en donde la relación molar [ácido carboxílico alifático/unidades de anhidroglucosa de éter de celulosa] es hasta 12/1.
