“…The adsorption process was found to be dependent on temperature, with optimum activity at 30°C for the removal of CR by chitosan hydrobeads [151]. Both ionic interaction, as well as physical forces, were found responsible for binding of CR with chitosan.…”

Effluent generated by the textile industry can be highly coloured. Before the waste is disposed into receiving waters, colour removal is an important consideration. Because of their complex molecular structures, dyes present in the textile wastewater are not removed easily by conventional wastewater treatment processes. They are fairly stable to light, as well as heat, and resist biodegradation, thus posing a challenge to conventional physico‐chemical and biological treatment methods. Although adsorption technology using activated carbon has been considered to be an effective and proven technology, it has its limitations as it is expensive and necessitates regeneration. As cost is an important consideration in most developing countries, efforts have been made to explore the possibility of using various low‐cost alternatives that are biodegradable, abundant, readily available, and are derived from waste materials. This article is a compilation of the investigations carried out by numerous researchers (from 2002 onwards) on the effective use of different kinds of low‐cost adsorbents for the removal of specific dyes from textile wastewater.

“…Subsequent reduction of 46 with sodium borohydride in ethanol gave a 1:1 mixture of the corresponding benzylindanol and the respective benzylindene, as determined by 1 H NMR spectroscopy. It appears that one of the diastereomeric indanols is extremely sensitive to traces of acidic impurities. The crude product mixture was subjected to cyclization using polyphosphoric acid as a catalyst .…”

An Elusive Nonaromatic Goal behind the Centropolyindanes: Aufbau of Veratrolo‐Annelated Centropolyquinanes and Ozonolytic Abbau

et al. 2017

This study presents a potential experimental approach to the still elusive topologically nonplanar (K5) parent hydrocarbon, centrohexaquinane (1), by a construction‐dismantling (aufbau–abbau) strategy via electron‐rich aromatic centropolyindanes. A series of veratrole‐based centropolyindanes are synthesized and subjected to ozonolytic degradation. These include the 2,2′‐spirobiindanes 30–32, fuso‐diindane 33, triptindanes 34–36, tribenzotriquinacene 37, and tetramethoxycentrohexaindane 9. Spirane 30 and propellane 36 are characterized by X‐ray structure analysis. Ozonolysis of 32 and 33 gives a keto ester (59) and a dimethyl muconate (60), respectively. Dimethoxytriptindane 34 gives a [3.3.3]propellane‐cis,cis‐muconate (61) in good yield, the stereochemistry of which is determined by X‐ray structure analysis. Tetramethoxytriptindane 35 gives the [3.3.3]propellane‐bis‐muconate 62 along with a [3.3.3]propellane‐dialdehyde‐muconate (63). Hexamethoxytriptindane 36 furnishes three products of mainly intra‐dimethoxy cleavage, with the [3.3.3]propellane‐tris‐muconate 64 as the major component. X‐ray structure analysis of 64 reveals molecular C3 symmetry and all‐cis,cis stereochemistry of the three muconate groups. Hexamethoxytribenzotriquinacene 37 gives the triquinacene‐tris‐muconate 68, albeit in very low yield. Ozonolysis of tetramethoxycentrohexaindane 9 affords the bis‐muconate 10 in moderate yield, along with two further centrohexacyclic products of single‐wing degradation.
