“…Ni2O3 and cupric bromide are effectively catalysing hydrocarboxylation of acetylene to acrylic acid. Yield of acrylic acid was found to be 72.1% and selectivity 85.2% with a Ni2O3 catalyst at 235 °C [180]. Good catalytic conversion of acetylene (85%) and selectivity of acrylic acid (99%) under mild conditions (T = 40-50 °C) is achieved with a catalyst system consisting of a homogeneous catalyst Pd(OAc)2, with diphenyl-2-pyridylphospine as the phosphine ligands and trifluoromethane sulfonic acid as the acidic promoter [239].…”

“…Acetylene (ethyne), C2H2, is the simplest alkyne. Combustion of acetylene produces a high-temperature flame, because of its triple bond and high enthalpy of formation [179][180][181]. Acetylene is one of the main alkyne emission compounds.…”

“…Crude acetylene includes small quantities of impurities, such as phosphine, arsine, ammonia, and hydrogen sulfide. For chemicals manufacturing, the purity of acetylene have to be 99 vol % because impurities may poison the catalysts [180,184]. The demand for the high purity creates challenges for the utilization of acetylene emissions in manufacturing of chemicals.…”

“…In the commercial scale acetylene is used in the chemical industry to produce, e.g., acrylic acid, vinyl chloride, ethylene, acetaldehyde, acetic acid, and 1,4-butanediol [180,184,236,237]. Here we have reviewing shortly some chemical production possibilities starting from acetylene that could be interesting in the future.…”

“…Carbonylation of acetylene with a Ni(CO)4 catalyst was firstly found by Reppe in 1939. Acrylic acid can be produced by hydrocarboxylation of acetylene with carbon monoxide and water over a catalyst [180,184,238,239]. Recently, many researchers have suggested new catalytic material to hydrocarbonylation of acetylene [238].…”

Abstract:The treatment of volatile organic compounds (VOC) emissions is a necessity of today. The catalytic treatment has already proven to be environmentally and economically sound technology for the total oxidation of the VOCs. However, in certain cases, it may also become economical to utilize these emissions in some profitable way. Currently, the most common way to utilize the VOC emissions is their use in energy production. However, interesting possibilities are arising from the usage of VOCs in hydrogen and syngas production. Production of chemicals from VOC emissions is still mainly at the research stage. However, few commercial examples exist. This review will summarize the commercially existing VOC utilization possibilities, present the utilization applications that are in the research stage and introduce some novel ideas related to the catalytic utilization possibilities of the VOC emissions. In general, there exist a vast number of possibilities for VOC OPEN ACCESSCatalysts 2015, 5 1093 utilization via different catalytic processes, which creates also a good research potential for the future.

Considering the small amount of CO2 as a contaminant in industrial gas mixtures, developing CO2‐selective adsorbents exhibit advantages in directly obtaining pure C2H2 in one‐step to reduce the energy consumption. However, it is still a great challenge due to the essential molecular feature of C2H2, including the triple bond and high polarizability. Herein, a simple but effective CO2‐facilitated transport strategy is presented to realize the overwhelming adsorption of CO2 over C2H2 by constructing core–shell composite structures using ionic liquid (IL) and metal‐organic framework (MOF). With the aid of excellent solubility of CO2 in IL and almost total exclusion of C2H2, the obtained materials boost molecular sieving‐based separation of CO2/C2H2. Density functional theory calculations combining molecular dynamic simulations revealed the solution‐diffusion mechanism for CO2, which is rarely reported in solid adsorbents. Ideal adsorbed solution theory selectivity for CO2/C2H2 with 1/1 and 1/3 volume ratios can reach over 104 and 4000 at 100 kPa with a high CO2 uptake of 40.3 cm3 g−1, superior to those of the reported materials so far. More importantly, this solution‐based separation strategy can avoid the difficulty for precise control of the regulation of adsorbent structure, which may be beneficial to practical production.

Precise engineering of organic porous polymers to realize the selective separation of structurally similar gases presents a great challenge. In this study, a new class of ionic porous polymers P(Ph3Im-Br-nDVB) with a high ionic density and microporous surface area are constructed through a facile copolymerization strategy, providing an efficient path to rational control over pore structure and functionality. The first example of ionic porous organic polymers is reported to address the challenge of discriminating the subtle difference of C 2 H 2 and CO 2 , which have almost identical molecular sizes and similar physicochemical properties, which achieve the highest C 2 H 2 / CO 2 selectivity (17.9) among porous organic polymers. These ionic porous polymers exhibit high stability and excellent dynamic breakthrough performance for binary C 2 H 2 /CO 2 mixtures, indicating their practical feasibility. Modeling studies reveal that anions are the specific binding sites for preferential C 2 H 2 capture because of Br − •••HCCH interactions. This study not only demonstrates an efficient strategy to build novel ionic porous polymers integrating abundant micropores and ionic sites but also sheds some light on the development of functionalized materials for the separation of structurally similar gas molecules.
