Title: Improved process for producing hydroxyethoxycellulose
IPC: C08B11/08
Filed: 1954-11-26
Abstract: Hydroxyethyl cellulose is continuously produced by forcing an aqueous solution of sodium hydroxide through a continuously travelling continuous sheet of dry cellulose pulp, removing excess sodium hydroxide solution from the sheet, and passing ethylene oxide through the moving sheet to substitute 2-8 per cent, advantageously about 3-5 per cent, by weight of ethylene oxide, based on the weight of the cellulose, the resulting hydroxy-ethyl cellulose being substantially completely soluble in 2-10 per cent aqueous sodium hydroxide solution at 0 DEG  C., but practically insoluble in water.  The concentration of the sodium hydroxide solution may be 10 to 50 per cent, e.g. 20 per cent, and the alkalized cellulose pulp sheet may contain about 36 per cent of cellulose and 17.5 per cent of sodium hydroxide.  The hydroxyethyl cellulose may be used to prepare aqueous solutions containing 4-15 per cent of hydroxyethyl cellulose of D.P. 200-600 and 2-10 per cent of caustic soda, e.g. a solution containing 8 per cent of the cellulose ether and 7 per cent of the alkali.  The solutions may be extruded at 25-65 DEG  C. into aqueous coagulating baths containing 4-15 per cent of sulphuric acid, 13-25 per cent of sodium sulphate and 0-15 per cent of zinc sulphate to form filaments or films.  In the example, a 20 per cent aqueous solution of sodium hydroxide is forced through a continuous travelling sheet of cellulose and the sheet is then led into a chamber in which ethylene oxide gas is forced through it at about 40 DEG  C. by contacting one side of the sheet with the gas and the other with a vacuum to etherify the sheet uniformly with formation of a hydroxyethyl cellulose in which 3 per cent of ethylene oxide, based on cellulose, is substituted.

Abstract: 1415706 Seismic prospecting IMPERIAL CHEMICAL INDUSTRIES Ltd 21 May 1974 [24 July 1973] 35104/73 Heading H4D In a method of seismic prospecting of an area under ice-covered water, seismic waves are generated by detonating a linear explosive charge suspended substantially vertically in the water at a sufficient depth below the ice to avoid breakage of the ice by the explosion. Embodiments described use PETN detonating cord as the charge, which has a weight on its lower end and is supported by the wires of an electrical detonator taped to the upper end of the charge. Geophones are linearly arranged on top of the ice, and shot holes through the ice are at intervals to give six-fold record stacking. Examples of charge lengths, depths and explosive loadings are given. The depth is preferably sufficient to avoid significant flexure of the ice, and the length sufficient that the gas bubble formed cannot oscillate as a sphere: hence spurious wave generation is minimized.
