L(+)-tartaric Acid Separations Using Aliquat 336 in n-Heptane, Kerosene, and 1-Octanol at 300 ± 1 K

Abstract: In the present study, extraction equilibria experiments for water + L(+)-tartaric acid + extractant/diluents were carried out at T = 300 ± 1 K for concentrations of L(+)-tartaric acid (0.1 to 1.0 mol·kg–1) and Aliquat 336 (0.22 to 0.88 mol·kg–1) in various diluents (n-heptane, kerosene, n-octanol). The equilibrium results were discussed in terms of the overall equilibrium complexation constant (KE(1:1)), loading ratio (z), extraction efficiency (E%), distribution coefficient (KD), dimerization coefficient (D), and partition coefficient (P). Kerosene + 0.88 (mol·kg–1) Aliquat 336 was found to be a favorable solvent with 50% extraction efficiency for the reactive extraction of L(+)-tartaric acid, whereas, 32.14% for n-heptane + 0.88 (mol·kg–1) Aliquat 336, and 22.22% for 1-octanol + 0.88 (mol·kg–1) Aliquat 336. 1:1 acid–amine complex was proposed for all the diluents with no overloading, that is, z < 0.5. A higher chemical extraction was observed in nonpolar diluents: n-heptane and kerosene. Further, equili...

Recent advancements in transparent carbon nanotube films: chemistry and imminent challenges

Abstract: Carbon nanotube (CNT)-doped transparent conductive films (TCFs) is an encouraging option toward generally utilized indium tin oxide-depended TCFs for prospective stretchable optoelectronic materials. Industrial specifications of TCFs involve not just with high electrical performance and transparency but also amidst environmental resistance and mechanical characteristic; those are usually excused within the research background. Though the optoelectronic properties of these sheets require to be developed to match the necessities of various strategies. While, the electrical stability of single-walled CNT TCFs is essentially circumscribed through the inherent resistivity of single SWCNTs and their coupling confrontation in systems. The main encouraging implementations, CNT-doped TCFs, is a substitute system during approaching electronics to succeed established TCFs, that utilize indium tin oxide. Here we review, a thorough summary of CNT-based TCFs including an overview, properties, history, synthesis protocol covering patterning of the films, properties and implementation. There is the attention given on the optoelectronic features of films and doping effect including applications for sophisticated purposes. Concluding notes are given to recommend a prospective investigation into this field towards real-world applicability. This graphical abstract shows the overview of different properties (mechanical, electrical, sensitivity and transportation), synthesis protocols and designing (dry and wet protocol, designing by surface cohesive inkjet-printed and the support of polymers), doping effect (general doping, metal halides, conductive polymers and graphene for transparent electrodes) and implementations (sensing panels, organic light-emitting diodes devices, thin-film transistors and bio-organic interface) of carbon nanotubes transparent conductive films.
