Title: Improvements in and relating to the production of barbituric acid and substitution products thereof
Filed: 1945-02-14
Abstract: Barbituric acid and its substitution products are prepared by forming an anhydrous alcoholic solution containing a malonic ester or cyanoacetic ester or the general formula CR1R11 (COOEt) or CR1R11(CN) (COOEt)-in which R1 and R11 are hydrogen or unsubstituted alkyl, aryl or aralkyl groups-and urea or a derivative thereof having at least two reactive hydrogen atoms and adding sodium alkyloxide to such solution at a rate which does not exceed the rate at which condensation occurs.  A test drop of the reacting mass is never allowed to cause more than a slight pink colouration when applied to moist phenolphthalein paper.  When methanol is the alcohol employed, it is preferred to raise the pressure to obtain a high reaction temperature.  The following examples are given:-(1) a solution of sodium in ethyl alcohol is added slowly to a dry solution of diethyl diethylmalonate and urea in ethyl alcohol so that a test drop taken from time to time never causes more than a slight pink colouration when applied to moist phenolphthalein paper.  The temperature is kept at 60 DEG  during the addition but raised afterwards to 80 DEG .  On removing the alcohol and acidifying, 5,5-diethylbarbituric acid is obtained in 82.5 per cent yield; (2) a solution of sodium in methanol is added slowly to a dry alcoholic solution of ethyl diethylcyanoacetate and dicyandiamide, and the 1-cyano-2,4-di-imino-5,5-diethylbarbituric acid obtained is converted to 5,5-diethylbarbituric by boiling with hydrochloric acid; (3) a solution of sodium in methanol is added slowly to a mixture of ethyl D 1,2cyclohexenylmethylcyano acetate and methyl acetyl urea in dry methanol and the 4 - imino - 3,5 - dimethyl - 5 - W1,2 - cyclohexenylbarbituric obtained is hydrolyzed by boiling with hydrochloric acid to give 5-W1,2-cyclohexenyl - 1,5 - dimethyl - barbituric acid; (4) a solution of sodium in ethanol is added slowly to a mixture of diethyl phenylethylmalonate and urea dissolved in dry ethanol to give 5-phenyl-5-ethylbarbituric acid; (5) 5,5-diethylbarbituric acid is similarly prepared in the apparatus of Fig. 2 (not shown) in which a jacketted reaction vessel is provided with a stirrer and a container for the sodium methoxide fitted with a pressure equalizing tube to equalize the pressure between the vessel and the container.

Abstract: 955,460. Identification sleeves for cables. HELLERMANN ELECTRIC Ltd. Feb. 1, 1963, No. 4197/63. Heading H1A. [Also in Division B8] A sleeve for an electrical component carries an identification mark which appears on a background panel which contrasts both with the mark and the sleeve. As shown in Fig. 1, the ohmic value of a resistor may be indicated by stretching over either the resistor or its terminal wires, a neutral coloured sleeve 10 of elastic material on the outer surface of which is printed through a stencil having a numeral masking, a background panel 11 having a oolour in accordance with the corresponding colour code of the numeral depicted on the stencil. Alternative embodiments are described in which either the sleeve 10 and mark 12 contrast against the neutral colour of the background panel and both have the colour according to the code or the sleeve, mark and panel are each of different colour. The coloured panels described are of rectangular shape or may extend the length of the sleeve as shown in Fig. 3. The advantage of the latter shape is that a series of short contiguous sleeves 10 may be out from a length of tubular sleeving 15 at the lines 16. Similarly sleeves having a series of numbers printed in panels of corresponding colours and joined to form a long tubular sleeve may subsequently be cut up into individual sleeves. For large diameter sleeving the panels 21 (Fig. 5) are repeatedly printed circumferentially to keep the area of imprinted sleeving surface to a minimum. The sleeve may be covered with a layer of transparent material to protect the printed panels.
