Patent GB-699456-A (GB)
Title: Cellulose ethers and process for making same
IPC: C08B11/08
Filed: 1950-05-31
Abstract: In the production of water-soluble cellulose ethers having 2-5 alkylene oxide groups per anhydroglucose unit, an anhydrous alkali-soluble, water-insoluble hydroxyalkyl cellulose ether is reacted with an alkylene oxide under heat and pressure and in the absence of a catalyst.  Ethylene oxide is the preferred etherifying agent, but propylene oxide also may be used.  The proportion of alkylene oxide may be 20-50 mols per C6H10O5 unit, the reaction temperature may be 80-110 DEG  C., and the reaction time may be 8-48 hours, e.g. 12-24 hours, at 13.6 atmospheres gauge pressure.  The moisture content of the cellulose ether starting material is kept as low as possible to prevent the formation of polyglycols by side reactions, and the starting material may be in the form of filaments and yarns or films or sheets.  In the example an alkali-soluble, water-insoluble substantially anhydrous cellulose ether having 0.1-0.5 ethylene oxide groups per C6H10O5 unit, and ethylene oxide in the proportion of 35 mols. of oxide per C6H10O5 unit of the cellulose ether molecule are maintained with agitation at 100 DEG  C. and about 200 p.s.i. gauge pressure for 12-24 hours in a sealed vessel.  After this the vessel is allowed to cool, the gas pressure is relieved and the product is removed.  The product may be dried at ordinary temperatures by allowing the ethylene oxide which it contains to evaporate spontaneously, the oxide being recovered by condensation. Since the product is obtained without the aid of a catalyst, it requires no other purification.  The products may be used for the production of effect and scaffolding yarns or microporous sheet materials such as filters (see Group I), hospital sheeting and surgical bandages.ALSO:Water-soluble cellulose ethers having 2-5 alkylene oxide groups per anhydroglucose unit, useful in the manufacture of microporous sheet materials such as filter media, are produced by reacting an alkali-soluble, water-insoluble hydroxyalkyl cellulose ether with an alkylene oxide such as ethylene oxide under heat and pressure and in the absence of a catalyst, (see Group IV(a)).  The filter media are made by forming a carded mat or felt, of desired thickness, of the water-soluble cellulose ether fibres and impregnating the same, so as to fill the spaces between the fibres and form an integral solid body, with a water-insoluble impregnant, such as a resin or rubber in liquid form.  The cellulose ether fibres are then dissolved out with water, leaving a microporous sheet.
