Patent GB-377795-A (GB)
Title: Improvements in the manufacture and production of cellulose compounds
IPC: C08B3/00
Filed: 1931-06-27
Abstract: Cellulose is treated with strong sulphuric acid solution containing 60 per cent or more of sulphuric acid in the presence of a neutral inert organic liquid which is miscible with the sulphuric acid employed, e.g. methyl acetate, ethyl acetate, or amyl acetate, and the cellulose sulphate produced is separated and treated with an organic acid until the sulphuric acid radicle is replaced by the organic acid radicle.  The organic liquid may be mixed with a second organic liquid, e.g. benzene, which itself is not miscible with the sulphuric acid.  The process may be applied to the treatment of cellulose esters containing a small proportion of organic radicle. The following examples are given: (1) cotton is treated firstly with 84 per cent sulphuric acid in presence of ethyl acetate, and then with glacial acetic acid.  (2) Sulphite pulp is treated as in (1) but using 90 per cent sulphuric acid. (3) Sulphite pulp is treated with 84 per cent sulphuric acid and ethyl acetate, separated, and acted upon with oleic acid.  (4) Wood pulp is treated firstly with 84 per cent sulphuric acid and amyl acetate, and then with glacial acetic acid.  The product is reacted with 98 per cent sulphuric acid in the presence of amyl acetate and benzene, separated, and finally treated with acetic acid.  (5) Cotton linters are treated with a mixture comprising 90 per cent sulphuric acid, amyl acetate, and benzene, filtered off, and reacted with acetic acid.  The Provisional Specification mentions also stearic acid as a suitable organic acid.

Class 86 An apparatus for producing solutions of plastic substances comprises a casing 1, a rotatable screw 2 forming with the casing a gap 43 through which plastic is conveyed in metered quantities to be kneeded and sheared and a trancated cone 3 integral with the screw and forming with the casing 1 another gap 44 in which the plastic is ground, mixed and dissolved by solvent supplied under pressure through nozzles 19, the first solution emerging from the gap 44 and discharged from an outlet 29. The screw and member 3 are rotated by a motor 18 through an infinitely variable gear box 17 and clutch 16, and are adjustable axially in the casing 1 by a thrust bearing 10a operable through a member 10, bolts 10c and nuts 10b. The screw 2 has a constant pitch but the depth of the thread gradually decreases, as does also the gap 43 as it progresses away from the loading hopper 11. The gap 44 also decreases at a uniform rate, towards the outlet of the casing 1. The nozzles are disposed around the casing on a helical curve and are supplied, by a multi-cylinder pump 22 driven by a motor 23, from a solvent tank 20. A heating jacket 25 is provided around the casing gap 43 whilst a cooling jacket 26 surrounds the outlet end of the casing gap 44. The hopper 11 is supplied with granulated plastic from a conveyer driven from an infinitely variable gearbox. The quantity of plastic supplied from the conveyer and also the dimensions of the gap 43 and speed of rotation of the screw can thus be accurately adjusted. Likewise the stroke of the pump piston can be accurately adjusted to meter the supply of solvent. The screw and member 3 may be provided with longitudinal and transverse flutings and may have projections interacting with the projections on the casing, to increase friction between the parts and the plastic. In a modification described with reference to Fig. 3 (not shown) the member 3 is separate from the screw and disposed at right angles thereto and it is adjustable axially in the casing. Other shapes of the member 3 and different forms of outlet are described with reference to Figs. 4 and 5 (not shown).
