Li, Ying published the artcileIsolation and characterization of a novel bacterium Pseudomonas aeruginosa for biofertilizer production from kitchen waste oil, Product Details of C4H10O2, the publication is RSC Advances (2018), 8(73), 41966-41975, database is CAplus and MEDLINE.

Kitchen waste oil is composed of long chain triglycerides (LCTs) that has high energy d. However, it is hard to be degraded by microbes, thereby leading to increasing levels of environmental pollution due to landfill disposition. In this study, we isolated and characterized a novel bacterium Pseudomonas aeruginosa PA-3 that could convert kitchen waste oil into biofertilizer. PA-3 could survive on trilaurin or kitchen waste oil as the sole carbon source, and 10 g L^-1 trilaurin or kitchen waste oil was completely consumed within 7 days. Interestingly, the degradation products of kitchen waste oil can be used as biofertilizer in promoting cabbage growth. The plant height, leaf area and stem diameter of cabbage plants were all increased with the addition of kitchen waste oil cultivation products into the soil. Kitchen waste oil degradation products were analyzed by gas chromatog. mass spectrometry (GC-MS), and short chain alcs. or fatty acids were observed to be the main products. To unravel the mechanism underlying the accelerated cabbage growth, bacterial diversity of the soil was investigated after using this biofertilizer. Results showed that agricultural probiotics accumulated with the addition of kitchen waste oil cultivation products. Finally, the whole genome of PA-3 was sequenced and analyzed, which showed the existence of a complete β-oxidation pathway in the genome of PA-3. To our knowledge, this is the first study on kitchen waste oil degradation and re-utilization by bacteria, which provides a new method for waste source re-utilization.

This work describes the selective H₂O₂ decomposition in the exit stream of the epoxidation reactor employed in the Hydrogen Peroxide-Propylene Oxide (HPPO) process. Pd/Al₂O₃ and Pt/Al₂O₃ catalysts were tested. The effects of the reaction temperature and the pH of the solution on catalyst performance were investigated. It was found that the Pt catalyst is much more active than its Pd counterpart. An increase in the temperature and the pH of the solution resulted in an increase in the H₂O₂ decomposition rate; however, a parallel increase of byproducts from PO was also observed Working with a Pt/Al₂O₃ catalyst under optimized reaction conditions (333 K, pH = 7), hydrogen peroxide can be completely decomposed at reaction times of 120 min with no byproducts produced from propylene oxide.

For the first time, a ∼100% sulfonic acid functionalized metal-organic framework (MOF), MIL-101-SO₃H, with giant pores (macroporous material) has been prepared by a hydrothermal process followed by a facile postsynthetic hydrochloric acid (HCl) treatment strategy. The replete readily accessible Lewis acidic and especially Bronsted acidic sites distributed throughout the framework as well as high stability endow the resultant MOF exceptionally high efficiency and recyclability, which surpass all other MOF-based catalysts, for the ring opening of epoxides with alcs. (especially, methanol) as nucleophiles under ambient reaction conditions. The synthesis of the target compound (catalyst) was achieved using chromium oxide (CrO₃) with 2-sulfo-1,4-benzenedicarboxylic acid sodium salt [i.e., 2-sulfoterephthalic acid monosodium salt] as reactants. Oxirane starting materials included 2-(phenyl)oxirane, 2-(methyl)oxirane, 2-(chloromethyl)oxirane, 2-oxiranemethanol and 2,2-dimethyl(epoxide). Regioselective ring-opening reaction products with alcs. included β-(methoxy)benzeneethanol, β-(ethoxy)benzeneethanol, β-(propoxy)benzeneethanol, β-(1,1-dimethylethoxy)benzeneethanol, 2-methoxy-1-propanol, 2-ethoxy-1-propanol, 2-propoxy-1-propanol and related compounds (primary alcs.). Secondary alcs. were also formed.

An, Ran published the artcileSynthesis of propylene glycol methyl ether catalyzed by imidazole polymer catalyst: Performance evaluation, kinetics study, and process simulation, Related Products of ethers-buliding-blocks, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2021), 126636, database is CAplus.

An imidazole polymer (divinylbenzene-vinylimidazole) catalyst (P-DVB-VIM) was developed for production of the eco-friendly solvent propylene glycol Me ether (PGME) by the propoxylation reaction of propylene oxide (PO) with methanol (ME). The catalyst was characterized in detail by SEM, Fourier-transform IR spectroscopy (FTIR), and Brunauer-Emmett-Teller (BET) anal. ¹H NMR was used to characterize the structural features of the catalyst precursor, i.e., the linear polymer of vinylimidazole (PVIM). An “electrophile nucleophile dual activation” ring-opening mechanism was proposed based on the “cooperative effect” of the reactant and PVIM. The catalytic performance was investigated and optimized at 100-130°C using an autoclave batch reactor. The results reveal that the P-DVB-VIM shows excellent catalytic performance, exhibiting the highest turnover frequency (TOF) number at 120°C within 45 min. The reaction kinetics was systematically studied using the pseudohomogeneous (PH) kinetic model. The kinetic parameters were determined by non-linear regression anal. of the exptl. data. Validation of the model showed that the exptl. data were in good agreement with the predicted outcomes. Moreover, based on the proposed kinetic model, steady-state simulations of the production of PGME in a fixed-bed reactor were carried out to determine the optimal design parameters, thus providing a useful guide for the design and production of PGME on the industrial scale.

Zeng, Bo published the artcileNitrogen-doped cobalt nanocatalysts for carbonylation of propylene oxide, Product Details of C4H10O2, the publication is Molecular Catalysis (2020), 111109, database is CAplus.

Nitrogen-doped cobalt nanoparticles loaded on porous supports were developed for ring-opening carbonylation of propylene oxide. The catalysts were prepared by simply pyrolysis of Co(OAc)₂/phenanthroline and supports. As proved by XPS combined with XRD and TEM characterizations, a higher amount of available Co-N sites were responsible for promoting the carbonylative activity. The selectivity of carbonylated products reached 93%, which is comparable to previously reported cobalt carbonyl catalysts. The novel type of carbonylative catalyst also could be reused and revealed fine stability due to the continuous generation of active [Co(CO)₄]^– species during reaction.

Hierarchies design of porosity in metal-organic frameworks (MOFs) has gained significant interest in recent years, and customization of mesoporous sizes in MOFs is still quite challenging. Herein, a template-free method by nucleation-competition has been developed to realize a near-linear control of the mesopore sizes (3-13 nm) in the hierarchical MOF UiO-66(Hf). High selectivity of enzyme adsorption, high activity of bulky-mol. catalysis, high stability of mesostructure, and extension to other MOFs further prove the success in the potential customization synthesis and applications.

Zhang, Zheng published the artcileSteam-Assisted in Situ Prepared TS-1 with Hierarchical Pores and Tunable Acid Sites Grown on Carbon Nanotubes Decorated Nickel Foam, HPLC of Formula: 1589-47-5, the publication is Industrial & Engineering Chemistry Research (2020), 59(7), 2761-2772, database is CAplus.

The TS-1 particles grown on carbon nanotubes decorated nickel foam (denoted as MTS-1S) are successfully synthesized by a steam-assisted crystallization method that does not waste the gels and is more convenient, economical, and efficient than the traditional hydrothermal method. MTS-1S possesses a hierarchical porous structure of micropores, mesopores, and macropores and a high content of titanium in the skeleton, which is beneficial for the diffusion of reactants and products and exhibits excellent catalytic performance for the epoxidation of propylene. The impact of water on the formation of acid sites has been demonstrated by d. functional theory (DFT). The acid sites of MTS-1S can be tuned by controlling the amount of water at the bottom of autoclave during steam-assisted crystallization, which significantly increases the selectivity to propylene oxide. Finally, the impact of acid sites of Si-OH and Ti-OH groups (Ti located in a defect structure, adjacent to Si-OH) on the reaction of epoxidation of propylene is confirmed by simulation.
