Organotin Complexes of Alizarin and Purpurin
(WILEY-V C H VERLAG GMBH, 2009)
Five novel organotin complexes with the anthraquinone dyes alizarin (1,2-dihydroxyanthraquinone) and purpurin (1,2,4-trihydroxyanthraquinone) were synthesized and characterized by elemental analyses, FTIR and NMR spectroscopy ...
Dyes used in pre-Hispanic textiles from the Middle and Late Intermediate periods of San Pedro de Atacama (northern Chile): new insights into patterns of exchange and mobility
(Elsevier, 2015)
Pre-Hispanic Andean textiles constitute the longest continuous textile record in the world, their structure
and design being one of the most significant markers of group identity in Andean populations. Since the
Late ...
Mecanismos y cinética de degradación del colorante purpurina (1,2,4-trihidroxiantraquinona) en medio acuoso por radicales hidroxílo
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. Coordinación de Servicios de Información., 2015-07)
La purpurina (1, 2, 4-trihidroxiantraquinona), pertenece al grupo de los colorantes quinónicos, los segundos más utilizados en la industria textil, estos tienden a ser recalcitrantes, tóxicos y difíciles de degradar mediante ...
