The complexation reaction between salen (Bis(salicylidene)ethylenediamine) and Cu(II) cations in methanol (MeOH), 2-propanol (2-PrOH), acetonitrile (AN), tetrahydrofuran (THF), and chloroform (CHCl3) as nonaqueous solvents at 25º C has been investigated. The stoichiometry and formation constants of complexes have been determined spectrophotometrically and conductometrically by method of continu...

Isobaric vapor–liquid equilibrium (VLE) data for 2-propanol + 1-butanol, 2-propanol + 1-pentanol, 1butanol + 1-pentanol and 2-propanol + 1-butanol + 1-pentanol were measured at 101.3 kPa by using an improved Rose still. All the binary VLE data have passed the traditional area test proposed by Herington. The interaction parameters for the Wilson, NRTL and UNIQUAC equations were determined by reg...

BACKGROUND To produce 1-propanol as a potential biofuel, metabolic engineering of microorganisms, such as E. coli, has been studied. However, 1-propanol production using metabolically engineered Saccharomyces cerevisiae, which has an amazing ability to produce ethanol and is thus alcohol-tolerant, has infrequently been reported. Therefore, in this study, we aimed to engineer S. cerevisiae strai...

The effects of aqueous and deuterium oxide (D2O) solutions alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol) on the thermomechanical properties poly(lactic acid)—PLA—films were assessed by dynamic mechanical analysis. glass transition temperature (Tg) PLA films immersed in 25%, 50%, 75%, 100% (v/v) alcoholic compared with Tg water D2O. methanol ethanol decreased as concentration a...

Constitutive fibroblast activation is responsible for organ fibrosis in fibrotic disorders including systemic sclerosis (SSc), but the underlying mechanisms are not fully understood, and effective therapies are lacking. We investigated the expression of the mitochondrial deacetylase sirtuin 3 (SIRT3) and its modulation by hexafluoro, a novel fluorinated synthetic honokiol analogue, in the conte...

The prolamin of maize (Zea mays L.), zein, was extracted from endosperm meal with 60% (v/v) 2-propanol/1% (v/v) 2-mercaptoethanol either directly or subsequent to extraction with 90% (v/v) 2-propanol. The zein extracted with 90% 2-propanol was essentially made up of 20 to 24 kilodalton polypeptides (alpha-zein) while that extractable with 60% 2-propanol/1% 2-mercaptoethanol contained, in additi...

A crystal structure of a carbamate of 2-amino-2-methyl-1-propanol (AMP-carbamate) has been elucidated and its structural and electronic properties investigated by density functional theory calculations and natural bond orbital analyses.

2-Propanol/acetone is a promising LOHC (Liquid Organic Hydrogen Carrier) system for fuel cell reactions. In this paper six different concepts 2-propanol/acetone are evaluated in Matlab simulation with respect to their thermodynamic integration and technical feasibility. Four of the use direct 2-propanol while other two first release molecular hydrogen from subsequently cell. The presented liqui...
