Swelling and peptization of cellulose in concentrated aqueous salt solutions, as a result of the action of the compressed hydrate water of these salts on the hydrolyzing dispersoid
Abstract
Working in 1902 with concentrated solutions of Mn(CNS)₃ and Ba(CNS)₂, and in 1905-1906 with a series of concentrated solutions of particularly readily soluble salts for the purpose of obtaining jellies of crystalline substances, I noticed that under the influence of these salts, filters swell and become so slimy that they slip through the narrow tube of the funnel in the form of a more or less gelatinous lump. According to my theory of peptization (1907-1908), cellulose is peptized because, at a certain high concentration of salt and a certain high temperature, it must transform into some truly soluble compound. The theory given above (see the article) can be generalized to any dispersoid that hydrolyzes into a soluble compound.
