Abstract

La presente descripción se dirige a métodos para producir un éter de celulosa de muy baja viscosidad teniendo poca o ninguna decoloración y productos de éteres de celulosa que resultan de ellos. El método incluye contactar un éter de celulosa con un agente oxidante y un ácido para formar una mezcla. La mezcla es calentada entonces y neutralizada. El método incluye adicionar un segundo agente oxidante a la mezcla y formar un éter de celulosa de muy baja viscosidad teniendo una viscosidad desde 1.2 cP hasta menos de 2 cP. El éter de muy baja viscosidad también puede tener un valor de color APHA de 1 hasta 100.
