Process for producing cellulose and a composite of magnesium hydroxide (II) and cellulose and aluminum hydroxide (III) using the cyclo-hexyl-ammonium ionic liquids

摘要

the subject of the invention is a new way to produce composite cellulose and magnesium hydroxide (ii) and cellulose and aluminium hydroxide (iii) using cykloheksyloamoniowych ionic liquids, applicable in the production of paper.in one solution process to obtain a composite cellulose and magnesium hydroxide (ii) and cellulose and aluminium hydroxide (iii) using cykloheksyloamoniowych ionic liquids is that liquid ionic specified general model 1 in which r1 is prostou0142au0144cuchowy under stawnik alkyl complex with 1 to 20 carbon atoms, or a substituted benzyl or allyl.and and the rest of the acidic organic acids specified general model 2, in which r2 is methyl proton, or group, or etoksymetylowu0105, or metoksymetylowu0105, or 2 - metoksyetoksymetylowu0105 or 2 - (2-methoxyethoxy) etoksymetylowu0105, the cellulose in the temperature from 20 to 120u00b0c, ilo quality from 0.05 to 30% by weight.then after reconstitution, the magnesium hydroxide (ii) or (iii) aluminum hydroxide in quantities of from 0.01 to 50% by weight calculated on the amount of added previously cellulose, after which the solution cools and added to the solvent.the crystallized composite cellulose and magnesium hydroxide (ii) or cellulose and aluminium hydroxide (iii) odsu0105cza and drought in temperature from 20 to 60u00b0c, for a period of 1 to 48 hours.
