Titanium tetrachloride catalyzes the formation of an equilibrium mixture of benzoylated noil-aromatic glucósidos in which the -isomer greatly predominates over the /3-isomer. The reaction provides a convenient method of preparing the -glucosides from their anomers.The transformation of the benzoylated /3-glucosides occurs more readily than that of the corresponding acetates. Application of the isorotation rules has indicated that when benzoates are compared with their corresponding acetates benzoylation is found to have increased the dextrorotation of the Cz-C8 portion of glucoside molecules and to have decreased the influence of the aglucone upon the rotation. Six new, crystalline glucoside derivatives and a crystalline compound containing o-nitrophenol, titanium and chlorine in the ratio 2:1:2 have been prepared.
the Southern Regional Research Laboratory has initiated work on the application of resin formulations to cotton garments for the express purpose of imparting permanent creases to them. In its full scope, the project has two phases: application to finished garments and application to yard goods, with resin curing in each case being accom plished on the finished garment. Advantages and disadyantages of the processes are described. Methods of application, procedures, and results are given for application of a dimethylol cyclic ethylene urea (CEU) formulation to swatches of fabric and to gar ments. Description is given of the effect of a numler of variables, such as the effect of storage on impregnated cloth, possibilities of stripping, precautions in drying and curing, durability to laundering, effect of sizing, effect of catalysts, and results using related resins in varying the formulation. Ultimate objectives are given including cooperative work with other research agencies to utilize standard drycleaning equipment for commercial application, use on yard goods, and development of non-chlorine-retentive finishes suitable for white goods in imparting permanent creases to cotton garments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
