The proper selection of thermodynamic models is an important step in the design and simulation of CO2 removal processes using amine solutions. In this study, we aim to study the thermodynamic behaviour of the CO2 removal process by employing the extended-universal quasichemical (e-UNIQUAC) model...

Two new Ni(II) complexes, [Ni2(2-CMSN)2(bpp)2(H2O)4]·1.5H2O (1), [Ni(2-CMSN)(4,4′-bipy)1.5(H2O)]·0.75H2O (2) (2-H2CMSN = 2-carboxymethylsulfanyl nicotinic acid, bpp = 1,3-bi(4-pyridyl)propane, 4,4′-bipy = 4,4′-bipyridine), have been solvothermally synthesized and characterized by single-cry...

The mycelium (or conidia) of Aspergillus awamori NRRL 3112 was investigated for its ability to degrade phenol, catechol, 2,4-dichlorophenol and 2,6-dimethoxyphenol in high concentrations. The biodegradation studies were performed in a liquid medium with the phenolic compounds as a sole carbon an...

Nonheme iron(II) complex, [(N4Py*)FeII(CH3CN)](ClO4)2 (1) with pentadentate tetrapyridyl ligand (N4Py* = N,N-bis(2-pyridylmethyl)-1,2-di(2-pyridyl)ethylamine) has been shown to catalyze the oxidation of N,N-dimethylaniline (DMA) with H2O2, tert-butyl hydroperoxide (TBHP), peracetic acid (PAA), m...

This article presents the syntheses and characterization of five new compounds with the general formula [Hg2(SePh)2X2(PR2R′)2] (R = tert-butyl; R′ = 4-N,N-dimethylaniline), where X = Cl (1a), Br (1b), I (1c), SCN (2), SePh (3). The compounds crystallized as dimeric {HgSe} units, although most ...

Polyalcohol is one of the important medium temperature phase change materials (PCMs) for thermal energy storage, in which liquid-free solid–solid PCMs are more promising although sublimation can hardly be avoided when crystals transform to the “plastic phase”. We reported here the preparation...

Urea-formaldehyde (UF) foams with robust siloxane coating were successfully prepared by grafting 3-aminopropyl-terminated poly-(dimethylsiloxane) (APDMS) and using 1, 6-hexanediol diglycidyl ether (HDE) as the bridging molecule. Compared with pristine UF foam and UF-g-APDMS foam, after immersion...

Recently, there has been a rapid growth in research and innovation in the synthesis of UF resins in the wood-based composites area. Much effort has gone into increasing their mechanical performance to extend the capabilities and application of this group of materials. This paper, for the first t...

The syntheses, thermodynamic and kinetic properties of a series of 2-styryl-1-benzopyrylium compounds are reported. This family of compounds was found to follow the same pH- and light-dependent network of chemical reactions previously described for flavylium (2-phenyl-1-benzopyrylim) compounds. ...

The pyranostyrylbenzopyrylium moiety is a new type of benzopyrylium derivative, which has an extra double bond between the benzopyrylium and the phenyl ring B and an additional pyranic ring between C-5 and C-4. In this work, the synthesis and the chemical equilibrium of a new 10-methylpyrano-2-s...

From the rhizomes of Cryptocoryne spiralis two new oxo fatty acids, 22-oxononacosanoic and 26-oxohentriacontanoic, have been isolated and their structure established by spectral data and chemical studies.

This paper, describing electron ionization mass spectral fragmentation of some hydroxycarboxylic and oxocarboxylic acid trimethylsilyl derivatives, focuses on the formation of fragment ions resulting from the interactions between the two functionalities of these compounds. These interactions res...

A multi-step product recovery process for 12-, 13- and 14-hydroxypentadecanoic acids was developed. Biotransformation of pentadecanoic acid by whole cells of recombinant E. coli K27 (pCYP102, pGEc47), synthesizing cytochrome P450BM-3 monooxygenase [EC 1.14.14.1], led to the production of 12-, 13...

The degree of hydrophobicity in cationic polymers plays an important but often underappreciated role in the safety and efficacy of gene delivery processes. In order to further elucidate structure-activity relationships of biodegradable cationic poly(carbonate) gene carriers, we synthesized a ser...

As proteasome inhibitors, a series of novel macrocyclic dipeptide N-benzyl amides were designed, synthesized and evaluated. Most of them exhibited potent proteasome inhibition and excellent anti-proliferative activity against RPMI 8226, MM1S, and MV-4-11 cell lines. As the most distinguished one...

Viologen (V) based molecules are classic and prestigious electrochromic (EC) materials which have dramatic optical contrast and tunable coloring states in solution-type electrochromic devices (ECDs). However, the stability of viologen based ECDs was significantly reduced by the dimer formation, ...

Benzyl methyl ether (BME) compounds are largely synthesized by the chemical industry for use as a starting material for the synthesis of other organic compounds. In order to achieve the target of green chemistry, BME can be synthesized from benzyl alcohol and dimethyl carbonate (DMC) using a zeo...

A series of low-cost and easily prepared benzyl substituted imidazolium ionic liquids are firstly synthesized and employed as catalyst for the cycloaddition of carbon dioxide with epoxides without any solvent and co-catalyst. The synthesized imidazolium ionic liquids are characterized by 1H NMR,...

Hyperbranched aliphatic polyethers containing hydroxyl and amine end groups were produced from glycerol carbonate (4-hydroxymethyl-1,3-dioxolan-2-one) and cyclic carbonate bearing phthalimide moieties.
