Title: Process for the manufacture of barbituric acid compounds
Filed: 1936-05-29
Abstract: 5 : 5-Disubstituted barbituric acids, in which one of the substituents is an isopropyl or isobutyl group and the other is a crotyl group, are prepared by condensing crotyl-malonic acids or crotyl-cyanacetic acids containing an isopropyl or isobutyl substituent, or derivatives thereof such as halides, esters, amides, nitriles or amide acid esters, with urea or its derivatives, e.g. guanyl-urea, guanidine, thiourea, isourea ethers, dicyandiamide or acyl compounds of urea and its derivatives, the products formed being converted, if necessary, into the barbituric acid.  Alternatively, the crotyl group is introduced into a 5-isopropyl or -isobutyl-barbituric acid or derivative thereof, or an isopropyl group is introduced into 5-crotyl-barbituric acid or a derivative, by reaction with the appropriate halide, and the product converted, if necessary, into the barbituric acid.  The products, which possess therapeutic properties, may be transformed into their salts directly or by double decomposition.  According to the examples: (1) crotyl-isobutyl-barbituric acid is prepared by condensing crotyl-isobutyl-malonic acid ethyl ester with urea, acetyl-urea, guanidine or guanyl-urea in alcoholic solution containing dissolved sodium; when using guanidine or guanyl-urea, a subsequent treatment with boiling dilute sulphuric acid is necessary; (2) isobutyl-barbituric acid in alcoholic caustic soda solution is treated with crotyl chloride or bromide, advantageously in the presence of copper or copper compounds as catalyst; the product may be converted by means of sodium ethylate into its sodium salt, from which the calcium salt is obtained by double decomposition; (3) isopropyl-barbituric acid is reacted in caustic soda solution with crotyl bromide; the resulting crotyl-isopropyl-barbituric acid may be converted into its sodium or calcium salts or into salts with ethylene diamine, diethylamine, diethylamino-ethanol or piperazine; (4) crotyl-isobutyl-malonic ester is heated with dicyandiamide in the presence of sodium dissolved in methyl alcohol and the product boiled with dilute sulphuric acid; (5) crotyl-isobutyl-malonic ester and thiourea are heated together in alcohol containing dissolved sodium and the resulting thiobarbituric acid treated with nitric acid; (6) crotyl-isobutyl-malonyl chloride is reacted with urea. Crotyl-malonic, -cyanacetic and -barbituric acids and their derivatives are prepared by reacting upon the respective compounds containing no crotyl group with crotyl bromide in the presence of an alkali metal alcoholate.

Abstract: 886,533. Drying foods, animal and vegetable substances. BIRS BRIT A.G. May 13, 1958 [May 17, 1957; Dec. 20, 1957], No. 15328/58. Drawings to Specification. Class 49. [Also in Groups III and IV (b)] A process for producing powders or concentrates from solutions or suspensions comprises spraying the solution or suspension downwardly in a tower in the form of a rain of particles of diameter 5-2000 microns and providing an upwardly flowing stream of air or other gas introduced at a temperature of 0-60 C., the conditions being adjusted so that the time during which the particles fall in contact with the air or other gas is not less than 5 seconds and the humidity of the gas passing out of contact with the particles is not less than 65%. The stream of gas is preferably pre-dried, e.g. by freezing or passing over a dehydrating agent. The gas may be air when the materials being dried are insensitive to oxygen or an inert gas, such as carbon dioxide or nitrogen, if they are sensitive to oxygen. The gas is preferably filtered to free it from dust particles. When the treated material is subject to enzymatic or fermentative reactions the gas may also be sterilized. Suitable gas velocities are 0.01-3 meters/second. A suitable tower for the production of powders has a height of about 50 meters and a diameter of 5-80 meters. Auxiliary towers operating as preliminary concentrating towers or wash towers may also be provided. The towers may be provided with a packing, e.g. Raschig rings or spiral bodies, bubble caps and screen bottoms. Auxiliary devices such as heat exchangers and heat equalizers may be provided for purposes of economy. An annular free space may be provided along the walls of the tower in which no droplets fall, but only gas rises to prevent particles settling on the walls. The spraying device may be mounted at a distance of 2-10 meters from the top of the tower. The gas stream may be introduced at the lower end of the tower either tangentially or horizontally or so that it rises straight up without spiral motion. The tower may have an intermediate, airpermeable, flat bottom at 0.5-0.6 meters above the actual bottom to retain the dehydrated product. Applications of the process.-The process is particularly applicable to dehydrating highly heat-sensitive and delicate chemical, pharmaceutical and food products. Extensive lists of materials which may be treated are given representative materials being: fruit and vegetable juices and pastes; milk products, including milk, butter and cheese; eggs; yeast; coffee and tea extracts; vitamins and hormones; natural and synthetic jellies; blood, blood plasma and liver extracts; heatsensitive dyes ; hygroscopic sugar products such as honey; malt preparations; puddings, cream sauce mixes and pasty starch slurries. Particular reference is made to the use of the process to obtain anhydrous lactic acid (see Group IV (b)).
