Title: Improvements in the pretreatment and esterification of cellulose
Inventor: MARTIN MERVIN ELLIS
IPC: C08B1/02
Filed: 1951-04-20
Abstract: Cellulose which initially contains less than 5 per cent. of water is pretreated with a lower aliphatic acid, i.e. one containing 1-4 carbon atoms in the molecule, in two stages, in the first of which there are present 4-9 per cent. of water, calculated on the dry weight of the cellulose, but no esterification catalyst, this stage lasting for at least 2 minutes, and in the second of which there is used a further quantity of lower aliphatic acid containing an esterification catalyst in an amount of 3-15 per cent. of the dry weight of the cellulose, this stage lasting for not more than 15 minutes and being effected under conditions of temperature such that at the end of the pretreatment part or all of the lower aliphatic acid is frozen. cellulose containing the frozen aliphatic acid is immediately subjected to esterification with an organic acid anhydride.  The process may be used in the production of cellulose acetate, acetic acid being used as the pretreating acid and also as the solvent for the cellulose acetate, sulphuric acid being used as the catalyst, and acetic anhydride as the esterifying agent.  The process may also be used in the production of cellulose propionate, butyrate, aceto-propionate, and aceto-butyrate.  The cellulose may be cotton linters, purified wood-pulp, or pulp from flax. hemp, grasses, peanut hulls, and bark.  The cellulose may be treated in the form of loose fibres or in sheet form.  The temperature during the first stage of pretreatment may be 25-55C.  The second stage may last for 2-5 minutes and there may be present 100-600 per cent. of the lower aliphatic acid calculated on the dry weight of the cellulose. When acetic acid is used, the temperature may be reduced to 15 DEG C. to cause freezing.  In an example, cotton linters are dried at 100 DEG C. until they contain 0.3 per cent. of water.  Acetic acid, containing 6 per cent. of water, calculated on the dry weight of the cellulose, is sprayed on to the linters, which are then allowed to stand for 3 minutes.  The linters are then sprayed with acetic acid containing 15 per cent. of sulphuric acid, based on the cellulose, and during 4 minutes the temperature of the mass is reduced to 15 DEG C. so that a large proportion of the acetic acid is frozen.  The linters are then acetylated by treatment with acetic anhydride, the temperature rising to 35 DEG C.  The primary triacetate is ripened in the solution and then precipitated. Specifications 688,580, and 706,522 are referred to.

Abstract: 127,728. Curran, C. J. June 10, 1918. Cupped articles.-In a boring and surfacing machine for internally tapering the mouth and finishing the edge of a cartridge base, the work is inserted and held in a hollow mandrel for treatment, and. is positively removed therefrom, by a slidable carrier-bar. The bar h, slidable in a bearing k and in axial alinement with a hollow mandrel c which may be continuously rotated, is moved to the right by a handle l, which is then rotated to rest in a fork 15. The end of the bar is then clear of the mandrel, and the work d is placed in position between a projection 16 on a shaped nosepiece fixed to the bar, and a shouldered sleeve o<1> having limited sliding movement. The sleeve is acted on by an adjustable spring q between a flanged sleeve o<2> and a sleeve s which can be adjusted and fixed by a set-screw u. Ball bearings p are provided to facilitate rotation of the work d when gripped in the mandrel. The mandrel is provided with an interna. spring bush w, with slots to allow contraction to grip the work, and external bevels v, v<1> co-operating with corresponding surfaces in the mandrel to give the gripping action when the work is forced home. A sleeve 3 with flared mouth surrounds the rim 2 of the cartridge head when in place. The work is inserted by moving the bar h to the left with the handle l in an upright position, a pin n on the end of the bar passing through a recess 10 into a U-shaped channel 9 the branches of which are inclined towards the mandrel as shown. The pin n is caused to ride up either branch to a cover-plate 11 by rotating the handle l and bar h. The work is arrested by the bush w before the movement of the bar h is completed, so that the final movement due to the inclination of the channel projects the bar a limited distance through the work, causing the sleeve o<1> to slide on the bar and put the spring q in compression. The cutter-bar e, carrying cutters f, g for internal tapering and surfacing respectively, is advanced to act on the work, which is rotated by the mandrel. The projection 16 secures positive withdrawal of the work when the bar h is withdrawn. The channel 9 may have replaceable liners 13 where engaged by the pin n.
