Abstract

Different types of wood pulps are used to manufacture microcrystalline cellulose. Percentage of alpha cellulose depends on type of wood pulp. Both wood pulp soft and hard wood pulp are usually used to manufacturing microcrystalline cellulose. Though the production process of wood pulp has a major bearing on it’s quality, Soft wood pulp on most occasions has higher alpha cellulose content with excellent finished product quality in terms of yield, physical parameter i.e. bulk density, flowability and chemical parameters i.e. water soluble substances, ether soluble substances, degree of polymerization and residue on ignition. In this paper we examine different wood pulp effect on hydrolysis time and degree of polymerization of finished product microcrystalline cellulose. In this study we used four types of wood pulp and done reaction with same acid concentration, pressure, and temperature only hydrolysis time were different, after drying evaluate degree of polymerization of finished product MCC.

Keywords: Wood pulp, Hydrolysis reaction, microcrystalline Cellulose, degree of polymerization.
