Title: A process of preparing maleic and succinic acid from furfural
IPC: C25B3/23
Filed: 1926-05-18
Abstract: 253,877. Zaidan Hojin Rikagaku Kenkyujo (Assignees of Yabuta, T.). June 22, 1925, [Convention date]. Maleic and succinic acids, obtaining. - The acids are obtained by anodic oxidation of furfural. In an example, the anolyte consists of a solution or suspension of furfural in 5 per cent sulphuric acid and the catholyte of 10 per cent sulphuric acid. The electrodes consist of lead pipes through which cooling water is passed. The current density is about 0.02 amps. per sq. cm. and the temperature 35 C. The electrolysis is continued until the anolyte no longer gives the characteristic reaction of furfural with aniline. acetate, and the anolyte is then concentrated. The product contains 80 per cent succinic acid and 20 per cent maleic acid. These are separated by fractional crystallization. Alternatively, the current may be reversed to reduce the maleic acid to succinic acid. This is crystallized out. dissolved in hot water and recrystallized. In another example, a lead peroxide anode and a current density of 0.06 amps. per sq. are employed. The product in this case is mainly maleic acid. Maleic acid may be converted to fumaric acid by adding sufficient sodium chloride to correspond to the sulphuric acid present and boiling. Fumaric acid crystallizes. out and is recrystallized from hot water. Cerium, vanadium and manganese compounds may be added to the anolyte as catalysts.

Title: Improvements relating to carboxyalkylcellulose ethers and method of manufacturing same
IPC: C08B11/12
Filed: 1955-05-03
Abstract: Carboxyalkyl cellulose ethers are made by suspending finely-divided cellulose, having a bulk density of at least 4.5 lbs. per cubic foot and a particle size such that at least 85 per cent will pass through a 20 mesh screen, in a mixture of n-propanol and water, containing not over 35 per cent, usually 10-15 per cent, by weight of water, and reacting the cellulose with an alkali metal hydroxide and a carboxyalkyl halide.  In an example, 120 parts of cellulose flock having a bulk density of 7.1 lbs. per cubic foot and all passing a 20 mesh screen are suspended in a mixture of 2110 parts of anhydrous n-propanol and 229 parts of water.  Then 90 parts of 50 per cent caustic soda solution are mixed for 45 minutes with the slurry at 55 DEG  C. and thereafter 50 parts of monochloroacetic acid in 50 parts of anhydrous n-propanol are added over a period of 2 hours at 55 DEG C. Finally the temperature of the mixture is maintained at 70 DEG  C. for 4.5 hours and the reaction product is filtered off and dried.  If methanol is substituted for n-propanol no reaction occurs, and if ethanol and secondary butanol respectively are substituted for n-propanol the degree of substitution and reaction efficiency are lower than with n-propanol.  Other carboxyalkyl cellulose ethers, such as carboxyethyl-, carboxypropyl- and carboxybutyl cellulose may be prepared by the process of the invention and the chloroacetic acid (or its homologue) may be used in the form of one of its salts, e.g. the sodium or potassium salt. Specifications 623,276 and 670,094 are referred to.  Reference has been directed by the Comptroller to Specification 729,823.
