Book excerpt: This report presents a cost analysis of Hydroxypropyl Methyl Cellulose (HPMC) production from cellulose, methyl chloride, and propylene oxide. The process examined is similar to the processes owned Dow Chemical and ICI. In this process, cellulose is alkalized with caustic soda and then mixed with methyl chloride (dissolved in dimethyl ether) and propylene oxide, before passing through an etherification reaction. This report was developed based essentially on the following reference(s): US Patent 7402668, issued to Dow Wolff Cellulosics GmbH in 2008 Keywords: Hydroxypropyl Methyl Cellulose, CMC, Cellulose, Cellulose Ethers, Hoechst
