Title: Manufacture of fatty acid esters of cellulose or of derivatives thereof
IPC: C08B3/00
Filed: 1930-12-31
Abstract: In the manufacture of fatty acid esters of cellulose or of derivatives thereof, the cellulose or cellulose transformation product or derivative is pretreated with a small proportion of sulphuric acid-not exceeding 2 per cent of the weight of the cellulose-in the presence of a diluent, particularly a fatty acid, then partially esterified by the addition of a fatty acid anhydride after which the esterification is completed by the addition of one or more salts or esters of sulphuric acid with or without an addition of free sulphuric acid.  As compared with the two-stage process described in Specification 281,927, [Class 2 (ii), Cellulose &c.], there is a less rapid reaction in the second stage and strong cooling is not required; further the batches may be increased in quantity. Suitable salts or esters include sodium and ammonium sulphates and bisulphates, and diethylamine-, pyridine-, dimethyl-and diethyl-sulphates.  Generally, any acid binding substance may be used which does not form with sulphuric acid a compound insoluble in the esterification mixture.  The salts or esters may be added as such or may be produced in the esterification mixture by adding the acid binding substance and then free sulphuric acid.  Simple or mixed esters may be produced. As starting materials, in addition to cellulose there may be employed cellulose pretreated, e.g. with formic, acetic, or butyric acids; cellulose pretreated with inorganic acids, e.g. feebly nitrated cellulose; and cellulose ethers still having free hydroxyl groups.  In examples (1) 400 g. bleached linters, 1200 g. glacial acetic acid and 4 g. sulphuric acid are stirred or shaken together for 6 hours, after which 1200g. acetic anhydride is added and the mixture stirred at 20-30 DEG  C. until a uniform, smeary pulp is obtained; a mixture of 16,4 g. sodium acetate and 25,6 g. sulphuric acid, in 50-100 g. glacial acetic acid is then added and acetylation is completed after about 1 hour; (2) an aceto-butyrate is obtained in a similar manner using in the starting mixture 800 g. glacial acetic acid and 400 g. butyric acid; (3) a nitro acetate of low nitrogen content is obtained by proceeding as in (1) but by adding sodium nitrate in place of acetate at the second stage; (4) a nitroacetate is obtained by starting with nitrated cotton containing 2 per cent of nitrogen; in the second stage pyridine and sulphuric acid are added.  The esters may be hydrolysed.

Title: Improvements in or relating to filtration materials
IPC: B01D69/10
Filed: 1962-10-19
Abstract: A material for fine filtration, e.g. of aircraft fuel and gaseous products, comprises a fabric of natural or artificial fibres having deposited thereon a coagulated high molecular material in the shape of a three dimensional sieve with pores of a diameter of 0,3-3 microns, the number of pores per square centimetre being more than 106.  The material may be manufactured by stretching a fabric which has been de-aerated, upon a horizontal smooth surface, applying a layer of a coagulating solution of a high molecular material, e.g. nitrocellulose or polyvinyl alcohol, by means of a casting device, and after coagulation of the material, the layer thus produced is dried in the stretched state to a constant weight and to the shape of a filter plate.  The process may be performed continuously on an endless moving belt upon which the supporting fabric is carried after being unwound from a spool and which in turn passes through the individual operating stages, i.e. the removal of the air-bubbles from the fabric by means of a suitable liquid agent, e.g. acetone, applying the coagulating solution, accelerating the coagulation of the solution by the action of steam, water or similar medium, and finally drying the product to a constant weight and to the shape of a filter plate.
