Spectroscopic investigation of reducing endgroup derivatives of hydrocellulose

Abstract

SynopsisA series of reducing endgroup derivatives of hydrocellulose have been prepared and their suitability for spectroscopic endgroup analysis examined. Of the compounds examined, the semicarbazide, thiosemicarbazide, hydroxylamine, benzimidazole, ethylacetoacetate, nitrophenylhydrazine, and phenylosotriazole derivatives were for one reason or another unsuitable. The phenylhydrazine-p-sulfonic acid derivative has properties which would make it suitable for endgroup analysis, but unfortunately neither the glucose nor the cellobiow derivative could be prepared.The 1-phenylflavazole derivative, however, appears to be very suitable for endgroup analysis.
