Graphene-based adsorbents for water remediation by removal of organic pollutants: Theoretical and experimental insights

Graphene-based materials have emerged as promising candidates as adsorbents for water treatment. The high surface area, low production costs, large porosities and robustness makes them excellent materials for adsorption studies and removal of toxic compounds such as pesticides, dyes, aromatic polar and non-polar compounds, nitro compounds, halogenated compounds, antibiotics, etc. from aqueous solutions. In recent years, there have been many structural modifications in the 2-D graphene sheet for synthesizing superior materials such as graphene-metal composites, metal oxide composites, bio-composites, hydrogels, etc. for improving the structural properties and widen its applications. In this review, we have incorporated the examples from both experimental and density functional theory studies (DFT) for water remediation by removal of toxic organic pollutants using graphene-based materials from the recent literature, and have further outlined the challenges and future perspectives in this direction.

Evolution of products in the combustion of scrap tires in a horizontal, laboratory scale reactor

A horizontal laboratory reactor was used to study the evolution of byproducts from the combustion of scrap tires at five nominal temperatures (ranging from 650 to 1050 C) and different oxygen:sample ratios A model was used to calculate the bulk air ratio (lambda), and the oxygen consumption was discussed considering this ratio lambda. More than 100 volatile and semivolatile compounds were identified and quantified by gas chromatography mass spectrometry, plotting their yields vs the bulk air ratio and temperature. Five different behaviors considering the bulk air ratio and the temperature were identified.

Recent Advances in the Synthesis of Benzo[b]furans

Benzofuran itself is an oily chemical compound, extracted from coal tar, which is converted into a synthetic resin, used in different industries. Several derivatives of benzofuran occur naturally in some plants and are the scaffold in several natural products. However, most of them are synthesized via different synthetic routes. In this chapter, we try to highlight the recent advances in the synthetic approaches to this important heterocyclic system and wide variety of its derivatives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 2-Bromobenzofuran, you can also check out more blogs about54008-77-4

All-aromatic liquid crystalline thermosets as high temperatures adhesives

In this paper we will describe the synthesis and characterization of a novel series all-aromatic liquid crystal thermosets (LCTs) for high temperature (>100 C) adhesive applications. Our ester-based oligomers, end-capped with reactive phenylethynyl functionalities, were synthesized using a standard one-pot melt condensation technique. The obtained reactive oligomers exhibit low melting temperatures and low melt viscosities, which resulted in improved flow and surface wetting. The adhesive properties of our LCTs based on 4-hydroxybenzoic acid, hydroquinone and isophthalic acid were investigated using standard (ASTM) lap-shear experiments conducted at room temperature (25 C) and at elevated temperatures, i.e. 150, 200 and 250 C. Our LCTs were used on Al2024, MS and Ti6Al4V substrates and we found lap-shear values of 11, 12 and 16 MPa for Al, MS and Ti, respectively. For the Al2024 substrate the lap-shear strength remained constant up to 150 C and dropped to 4 MPa at 200 C. A post-mortem inspection of the fracture surface, using high-resolution scanning electron microscopy (HRSEM), showed that there was no adhesive failure at the metal substrate at room temperature or at elevated temperatures. The lap-shear values of our polymers are significantly higher as reported for other commercial available LCPs such as Vectra.

Base-Mediated Meerwein-Ponndorf-Verley Reduction of Aromatic and Heterocyclic Ketones

An experimental protocol to achieve the Meerwein-Ponndorf-Verley (MPV) reduction of ketones under mildly basic conditions is reported. The transformation is tolerant of a range of ketone substrates, including O- and S-containing heterocycles, is scalable, and shows potential to be used as a platform to access enantioenriched products. These studies provide a general method for achieving the reduction of ketones under mildly basic conditions and offer an alternative protocol to more well-known Al-based MPV reduction conditions.

Process comprises the combination of the three steps of condensing 3-N(R)2 -4-X-benzoic acid with an aromatic or heterocyclic aldehyde, Y-CHO, under acidic conditions to produce 3-Y-5-X-6-N(R)2 phthalide (II), condensing said phthalide with a compound of the formula Z-H under alkaline or acid conditions to produce 2-(alpha-Y-alpha-Z)methyl-4-X-5-N(R)2 benzoic acid (III), and oxidizing said benzoic acid to produce 3-Y-3-Z-5-X-6-N(R)2 phthalide (I) where: R is hydrogen, non-tertiary alkyl of one to four carbon atoms, benzyl or substituted benzyl; X is hydrogen or halo; Y is 4-R1 -3-R2 -2-R1 -phenyl, 1-R5 -2-R6 -5/6-R4 -3-indolyl, 9-R7 -3-carbazolyl, 9-julolidinyl, 3,4-dioxymethylenephenyl, 2-thienyl, 1-R8 -2-pyrrolyl, or 4-pyridinyl; and Z is 4-R1 -3-R2 -2-R1 -phenyl, 1-R5 -2-R6 -5/6-R4 -3-indolyl or 1-R8 -2-pyrrolyl which are useful as colorless precursor color formers in carbonless duplicating and in thermal marking systems.

One-pot synthesis of heteroaryl and diheteroaryl ketones through palladium-catalyzed 1,2-addition and oxidation

A synthetic method was developed for the preparation of heteroaryl and diheteroaryl ketones from aldehydes and organoboronic acids through a palladium-catalyzed 1,2-addition and oxidation that uses an aryl iodide as the oxidant. This one-pot process shows high tolerance for a broad range of heterocyclic substrates by using 1.0-3.0 mol-% of the catalyst that is formed from allylpalladium chloride dimer and a thioether-imidazolinium chloride. In addition to fine-tuning the catalytic system, the use of a sterically hindered aryl iodide that has a substituent at the ortho position, such as 2-iodotoluene, is important to obtain the desired ketones with heterocyclic moieties in good to excellent yields. The one-pot synthesis of heteroaryl and diheteroaryl ketones was achieved by a palladium-catalyzed 1,2-addition and oxidation. This catalytic process with 1.0-3.0 mol-% catalyst loading tolerates a broad range of heterocyclic substrates to give ketones with heterocyclic moieties in good to excellent yields. Copyright

Catalytic reforming of palm kernel shell microwave pyrolysis vapors over iron-loaded activated carbon: Enhanced production of phenol and hydrogen

This study addresses the in-situ microwave catalytic reforming of volatile matter from palm kernel shell (PKS) over iron-loaded activated carbon (Fe/AC) catalysts. The impacts of catalyst composition on the secondary gas-phase reactions and distribution of products were studied at 500 C. It was found that the Fe/AC catalyst promoted the yield of light gases. Using the 1%-Fe/AC catalyst, the yield of gaseous fraction peaked at 37.09 wt%. The selectivity of the deoxygenated products was promoted in the presence of Fe. Catalytic reforming of PKS pyrolysis vapors over Fe/AC drastically enhanced the generation of phenol and H2, the concentrations of which reached 75.09 area% and 75.12 vol%, respectively. Catalytic pyrolysis of syringol and guaiacol as model compounds showed that Fe/AC catalyst promoted the demethoxylation and deoxygenation reactions to selectively generate phenol which was explained by oxophilic reactivity of the active Fe sites.
