POLYMERS RELATED TO CELLULOSE.
Abstract
More condensation reactions of periodate oxycellulose are reported, and a reason is suggested to account for their non-quantitative nature. Some physical properties of the products, many of which are cross-linked, are given. Thiosemicarbazide and cyanuric hydrazide both fail to make oxycellulose flame-resistant, but a limited effect is obtained with phosphonitrilic hexahydrazide, which, even at the low add-on achieved, drastically reduces the amount of tar formed on pyrolysis. Thiosemicarbazones of several aldoses were prepared and, with the exception of that from D-glucuronolactone, were assigned cyclic structures. Periodate-oxidised methyl 4,6-0-benzylidene-alpha-D-glucoside (OMBG) reacts with ethanolamine to form an oxazolidine derivative. Treatment of OMBG with MeOH in the presence of acid leads to removal of the benzylidene group and simultaneous methylation; the product was identified and characterised. Condensation of OMBG with phenylurea yielded a compound of unknown structure; a nitrogen-free product results from treatment with methanolic hydrazine. (Author)
