G. Rozmarin et al., CHEMICAL MODIFICATION OF FURFURAL LIGNOCELLULOSE - LIGNOCELLULOSIC DYES, Cellulose Chemistry and Technology, 29(6), 1995, pp. 691-703
Ate-dyes based on furfural lignocellulose from sunflower akenes ha le
been synthesized by step reactions of nitration-reduction-diazotizatio
n and coupling. The compounds obtained have been characterized by FT-I
R, H-1-NMR, spectroscopy, elemental analysis, and by their solubility
in various organic solvents. Cellulosic films coloured with the newly
synthesized dyes ha-re orange and red tint and present good light fast
ness.
