Abstract
Cellulosic materials which contain free hydroxy groups, or yield them under the conditions of reaction, are etherified in the presence of tertiary alicyclic organic bases. The cellulosic material may be in the form of fibres, flakes, yarn, foils and the like, and may comprise, for example, cellulose acetate or regenerated cellulose yarn. Specified bases are dimethylamino-cyclobutane, -cyclopentane, -cyclohexane, and -cycloheptane, diethylamino-cyclohexane, N-dimethyl cyclobutyl-methylamine, methyl-dicyclohexylamine, and ethyl-dicyclohexylamine. The etherification is preferably carried out in an anhydrous medium, and in the presence or absence of a diluent. Alkylating, aralkylating, hydroxyalkylating, or carboxyalkylating agents may be used as the etherifying agents, and a number of these are specified. Cellulose ethers which contain free hydroxy groups may be further treated, e.g. with esterifying-agents, or according to the second Provisional Specification, with etherifying-agents.
