Although sodium xanthates of cellulose form the basis of the cellophane and viscose rayon industries and are of great commercial importance, no reliable information about the detailed chemical structure of these xanthates exists. A considerable amount of knowledge concerning the…

The existence of cellulose sodium xanthate has been known for over 60 years; the salt forms the basis of the important commercial process for making viscose rayon and cellophane. Yet, until very recently, no detailed knowledge of the chemical structure…

The expanding use of wood pulp and pulp products has emphasized the need for increased basic knowledge dealing with the waste materials and by-products of the forest industries. Wood bark is one or the major byproducts. In the paper industry…

The large-scale production of synthetic rubber has shown the necessity of obtaining fundamental knowledge concerning the chemical structure of polymers and copolymers. The mechanical and chemical properties of the final polymer and ease of processing have been found to be…

Over sixty years ago the first chemical investigations were reported on waste sulfite liquor from the pulping of wood, but despite a large volume of research in the intervening period, the sulfonation reaction and its products remain an intriguing unsolved…

As knowledge in chemical kinetics has advanced from the first study of reaction rates by Wilhelmy (1) in 1850, it has become increasingly clear that many reactions take place by a sequence of simple steps, or elementary reactions. This implies…

Kojic acid can be produced by a microbiological process from carbohydrates, and therefore it might serve as a very useful outlet for industrial and agricultural carbohydrate wastes. Since the acid has not yet found practical applications, the present research is…

During the steps employed in the conversion of the standing tree to wood pulp about two-thirds of the original plant material is discarded, and of the many hundreds of compounds present in the tree only cellulose is utilized to an…

Note: Missing title page., Several years ago the Wood Chemistry Committee of the Technical Section, Canadian Pulp and Paper Association, observed that chlorine dioxide was becoming of importance as a bleaching agent for pulps, and that more detailed knowledge concerning…

The biological significance of certain pyridinium betaines, such as diphosphopyridine nucleotide and triphosphopyridine nucleotide, has been fully recognized. The vital importance of these substances in the life of organisms provided an impetus for extensive research in this field, with the…
