Abstract

La presente invención se refiere a un proceso para producir un éter de celulosa esterificado que comprende la etapa de hacer reaccionar un éter de celulosa con un anhídrido de ácido monocarboxílico alifático y/o un anhídrido de ácido dicarboxílico y con un agente despolimerizante, en donde el éter de celulosa tiene una viscosidad inicial de al menos 500 mPa•s, medido como una solución al 2% en peso en agua a 20 °C, y la reacción del éter de celulosa con el anhídrido de ácido monocarboxílico alifático y/o el anhídrido de ácido dicarboxílico y con el agente despolimerizante se conduce simultáneamente o en secuencia en un dispositivo de reacción.
