Abstract: Reduction of 2,3-dicarbonylcellulose hydrazone gives rise to 2,3-deoxydihydrazinocellulose. Reaction of 2,4,6-trichloro-s-triazine with cellu­lose enables one to prepare 2,4-dichloro-6-oxycelluloso-s-triazine followed by 2,4-dihydrazino-6-oxycelluloso-j-triazine and after that by (2,4-dihydrazino-6-s-triazino)-2,3-dicarbonylcellulose, (2,4-dihydrazino-6-s-triazino)-2,3-dihydrazonocellulose and (2,4-dihydrazino-6-s-triazino)-2,3-deoxydihydrazinocellulose, respectively. The dihydrazino derivatives give through condensation with 5-nitro-2-furaldehyde the appropriate 5-nitrofurfurylidene derivatives. The behaviour of some of the selected materials being under thermogravimetric conditions is presented.
