Patent GB-479445-A (GB)
Title: Improvements in the manufacture of ethers of cellulose and other carbohydrates
IPC: C08B11/20
Filed: 1936-08-05
Abstract: The viscosity of carbohydrate ethers is reduced by subjecting them to treatment with an agent containing or yielding free oxygen in the presence of a base.  Preferably, the treatment is effected by subjecting the ethers in granular form to aeration, e.g. by passing air (which is preferably freed from carbon dioxide) through the ethers, or by subjecting them to treatment in a closed vessel with the air under pressure.  The process is particularly useful when applied to oxyalkyl ethers of cellulose such as are made by the processes described in Specifications 463,317 and 473,975.  The products may be used as thickeners for printing pastes or sizes, according to the amount by which the viscosity is reduced.  According to the Provisional Specification, ripening of the carbohydrate ethers may be effected by impregnating them with an oxidizing agent, e.g. potassium permanganate, chlorate or nitrate, or hydrogen peroxide, and allowing them to stand in an oxidizing or non-oxidizing atmosphere.
