摘要:
The present invention relates to a process for producing microcellulose comprising subjecting fibrous cellulosic material to acid hydrolysis at a temperature from 10° C. to less than 140° C. and at a consistency of at least 8% on dry weight of the cellulose, wherein the amount of added acid is from 0.2 to 2%, preferably from 0.3 to 1.9%, more preferably from 0.5 to 1.5% on dry weight of the cellulose.
