Title: Improvements in or relating to the manufacture of barbituric and thiobarbituric acids
Inventor: DONNISON GEORGE HALL
Filed: 1955-06-15
Abstract: Barbituric and thiobarbituric acids of the general formula <FORM:0825832/IV (b)/1> (wherein R and R1 are hydrogen atoms or alkyl, alkenyl, cycloalkyl, cycloalkenyl or aryl groups, R3 and R4 are hydrogen atoms or alkyl groups containing at most 6 carbon atoms and X is oxygen or sulphur) are prepared by condensing an appropriate malonic acid dialkyl ester (the alkyl groups each containing at most 8 carbon atoms) with a metallo derivative of an appropriate urea or thiourea at a temperature not exceeding 65 DEG  C. and recovering the free acid also at a temperature not exceeding 65 DEG  C.  The metallo derivative may be formed in situ or it may be preformed, from the urea and an alkali metal or the alcoholate, hydride, cyanamide or amide thereof.  The condensation is preferably effected in presence of an excess of the urea component, and the acid is advantageously recovered by diluting the reaction mixture and then adding dilute acid such as acetic acid.  In examples the condensations are performed in methanol in presence of sodium methoxide or, in one example, in ethylene diamine, excess solvent being removed, when necessary, by vacuum distillation.  The use of other solvents such as lower alkanols and dimethylformamide is also referred to.  The groups R and R1 in the exemplified products have, variously, the values ethyl, 1-methyl-butyl, allyl, sec.-butyl, n-butyl, iso-amyl and phenyl, and N-alkyl barbituric and thiobarbituric acids are also referred to.  Reference is also made to the preparation of alkali and alkaline earth metal and organic base salts of the barbiturates and thiobarbiturates.  The Provisional Specifications define the invention in somewhat wider terms.

Title: Improvements in the production of 2.3-dihydrofuranes
Inventor: DIMROTH PETER
Filed: 1959-05-26
Abstract: 2,3- dihydrofuranes are produced by treating alkane-diols-1,4, having at least one primary or secondary hydroxy group, in the liquid phase at elevated temperature with a catalyst which contains cobalt metal. The preferred starting materials are butane-diols (1,4) which are substituted by alkyl radicals having up to 3 carbon atoms.  The catalyst is preferably applied to a carrier, e.g., aluminium oxide, silica gel or aluminium phosphate, and may also contain activators which promote dehydrogenation and/or dehydration, e.g., zinc, manganese, copper, silver, palladium, chromium, phosphoric acid and acid phosphates. Preferably a supported catalyst contains 10-30% by weight of cobalt.  If an activator is used it is preferably present in amounts of 0,1 to 10% by weight based on combined cobalt and carrier.  The reaction is preferably carried out at 160 DEG -250 DEG C. In some cases it is advantageous to add a high-boiling carboxylic acid, e.g, caproic, caprylic, capric, lauric, palmitic or stearic acid.  Examples are given of the conversion of butane-diol-1,4 to 2,3-dihydrofurane, 1-methyl-butane diol-1,4 to 2-methyl-2,3-dihydrofurane and 5-methyl-2,3-dihydrofurane, 1,4-dimethyl-butanediol-1,4 to 2,5-dimethyl-2,3-dihydrofurane, and 1,1-dimethyl-butanediol-1,4 to 2,2-dimethyl-2,3 dihydrofurane.
