Description

One of three forms of Cellulose: alpha, beta, and gamma. The three forms may be separated by soaking the cellulosic pulp in a 17.5% solution of Sodium hydroxide. The pure white, alpha cellulose is insoluble and can be filtered from the solution. Once the alkaline solution is neutralized, beta cellulose will precipitate. Gamma cellulose is the portion of the cellulosic material that remains soluble. Together, gamma and beta cellulose are called Hemicellulose.
