“…[2][3][4][5][6][7] ACs represent an environmentally benign and cheaper alternative catalysts on processes related to the fine-chemical synthesis. [8] In this sense, microporous ACs have been successfully used in several catalytic reactions, such as the synthesis of a,bunsaturated nitriles, [9] N-alkylation of imidazole, [10][11][12][13][14][15][16] chalcones, [17] and epoxide ring-opening reactions. [18,19] One of the main advantages of using mesoporous carbons is the presence of meso-and macroporous networks which may result in a more efficient selectivity towards the formation of products.…”

We describe the first examples of Friedländer reactions efficiently catalyzed by carbon materials. We report herein a series of acidic activated carbon materials, which can be considered as an environmentally friendly, cheaper alternative to the traditional acidic mesoporous silicates or even zeolites for the synthesis of quinolines/quinolones. Textural parameters of the acidic activated carbon materials together with their acidic properties are important factors that affect the reaction selectivity. Some mechanistic details have been addressed by computational calculations.

An overview of the production of carbon fibers based on lignin is presented. The structure, isolation, and properties of lignin are first discussed in the context of their effects on carbon fiber production. A general overview of carbon fiber manufacturing is then presented to provide background for a discussion of previous and current research on lignin-based carbon fiber. Current research on fiber spinning, thermostabilization, and carbonization of lignin is reviewed and directions for future research are discussed. Finally, emerging new opportunities for lignin-based carbon fiber in non-structural applications are presented, highlighting recent research from our laboratory on the production of sub-micron and nanometer scale carbon fibers by electrospinning of lignin. IntroductionCarbon fibers (CFs) are rather unique materials which can simultaneously display high tensile strength (up to ∼7 GPa), high tensile modulus (up to 900 GPa), and low density (ρ = 1.75-2.00 gcm −3 ). 1 These properties make CF an ideal reinforcement material in high-strength, lightweight composite materials used in aerospace, automotive, marine, and sporting goods applications. 1−4 The electrical, thermal, and surface properties of CF can also be engineered to exhibit different characteristics, making them useful as adsorbents, 5 catalyst supports, 6 biomedical materials, 7 electromagnetic shielding, 8 and in other electrical applications 8 such as electrical double-layer capacitors (EDLCs) for energy storage or capacitive deionization, 9−14 Li + -ion batteries, 15−17 fuel cells, 18,19 and dye-sensitized solar cells. 20 Unfortunately, high cost is an obstacle to large-scale implementation of CFs and their composites for automotive and energy applications. The dominant precursor for CF today are synthetic poly(acrylonitrile) (PAN)-based copolymers. PAN precursor costs have been reported to account for approximately half of the manufacturing cost of high-performance CF, which was reported to be in the range of ∼US$12.25 to US$30/kg. 21 Replacement of PAN with lower-cost precursors could expand the range of applications for CF.

“…Zn 2+ hydrolyzes only sparingly in acid media to produce Zn(OH) + and Zn 2 (OH) 3 + before precipitation commences in the neutral region. In basic media, Zn(OH) 4 2-and perhaps Zn 2 (OH) 6 2-are formed [36] . SnCl 2 is readily soluble in water (178 g SnCl 2 /100 g H 2 O at 25 ºC [37] ) and, depending on concentration, is prone to hydrolysis decomposing to the basic salt Sn(OH)Cl, which precipitates, plus HCl [38] .…”
