  • Method for producing cellulose sulfoacetate derivatives and products and mixtures thereof
    Patent number: 6800754
    Abstract: A method for directly producing a mixture of cellulose sulfoacetate derivatives by esterification of cellulosic material, characterized in that it comprises the following steps i) the cellulosic material is suspended in a glacial acetic acid solution and the excess acetic acid is eliminated ii) the cellulosic acid that is swollen with acetic acid is suspended in a sulfuric acid solution in glacial acetic acid and iii) the cellulose material is made to react by adding acetic anhydride.
