Abstract

En la presente se proporcionan metodos mejorados para producir acido metacrilico y esteres de metacrilato utilizando etapas de procesamiento combinadas o "integradas" que incluyen hidrolisis integrada, sistemas de pirolisis integrados y combinaciones de estos. En una modalidad, se integran otros aspectos de trenes de produccion de acido metacrilico y ester de metacrilato. Tambien se proporcionan metodos para purificar corrientes de acido metacrilico crudo para formar acido metacrilico glacial que es al menos 95% puro.
