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
