Removal of reactive dyes by quaternized coconut husk [PDF]

open access: yes, 1998
Coconut husk modified through the use of N-(3-chloro-2-hydroxypropyl)- trimethylammonium chloride was evaluated for its ability to remove reactive dyes from aqueous solution. Sorption of dyes was pH dependent and favorable sorption occurred at low pH. In

Micellar dye shuttle between water and an ionic liquid [PDF]

open access: yes, 2011
The reversible transfer of poly(2-ethyl-2-oxazoline)-block-poly(2-nonyl-2-oxazoline) nanocarriers comprising encapsulated dyes is demonstrated between water and an ionic liquid. This dye transfer concept is shown to be applicable for loading and delivery

Synthesis, characterization and applications of some novel mordent and heterocyclic disperse dyes on polyester and wool fibers

open access: yesOrbital: The Electronic Journal of Chemistry, 2012
The novel mordent and disperse heterocyclic dyes were prepared by coupling of various diazo solution of aromatic amines with 1-[(2-butyl-2,3-dihydrobenzofuran-3-yl)]-1-(4-hydroxyphenyl)methanone. The resultant mordent and disperse heterocyclic dyes

Disperse Dyes from Alkylanthraquinones.II.

open access: yesJournal of Synthetic Organic Chemistry, Japan, 1965
A series of dispersing dyes containing a β-methyl group and an α-amino group have been synthesized in such a way that those substituents are not located in adjacent positions to each other on the ring structure. The starting compounds employed were the Diels-Alder adducts obtained from 2, 3-dimethylbutadiene with naphthazarine and with 5-nitro-2, 3 ...
