Oxycarboxylic acids

Cholesterol esters of poly-N-methacryloyl-co-amino-carboxylic and co-oxycarboxylic acids, respectively... 

Epoxides are most commonly formed by reaction of a per-oxycarboxylic acid with an olefin at room temperature. It is a one-step cycloaddition reaction ... 

In addition to aryl oxycarboxylic acids, aryl oxycarboxylic acid amides, aryl oxycarboxylic acid nitriles and, after oxidation, aryl oxyalkanoles can undergo /9-oxidation. 

Recently measurements by W. B. Bridgman on co-oxycarboxylic acids and their polycondensation products have strengthened this view. By internal esterification of co-oxydecanoic acid, long chains of molecular weight 900-14000 were obtained and very thorough measurements of refraction and polarization made on this material in dilute benzene solution over a wide wave length range. 

C5O5HK, as well as a normal salt, it probably contains two hydroxyl groups and they proved that it has two adjacent carbonyl groups hence the formula is (C0)3(C0H)2, probably IV. Oxycarboxylic acid is benzotriquinone or triquinoyl, which they formulated as V, although the alternative VI is preferable. Dihydrocarboxylic acid is tetrahydroxyquinone, formulated as VII. Nietzke and Benckiser deliberately avoided giving the distribution of the carbon valencies in the formulae (V is based on the Claus formula, see p. 802), but VII could be represented as a derivative of/>-quinone. ... 

Following is a balanced equation for the epoxidation of cyclohexene by a per-oxycarboxylic acid, RCO3H. In the process, the pero>qrcarboxylic acid is reduced to a carboxylic acid. 

To illustrate some further possibilities of zone electrophoresis in the different fields of chemistry it should be mentioned that inorganic ions (Lederer and Ward, 1952 Anderson and Lederer, 1952 Gustavson, 1952), oxycarboxylic acids (Wieland and Feld, 1951), porphyrin pigments (Papastamatis and Hensch, 1952), etc., have been separated by such procedures. 

The butyltin oxycarboxylates, BuSn(0)0C0R, which are formed by azeotropic dehydration of a 1 1 mixture of butanestannonic acid and the acids R C02H (R = Pr1 or Bu1), have been shown to be hexamers with a drum-shaped structure, as described in Section 12.3.9...
