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...

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...

vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using n2 carrier over a series of surface modified andunmodified zsm-5 (si/al= 60-170) loaded with h3po4, differing in the external surface treatment of the zeolites.the feed molar ratios of toluene/methanol and toluene/2-propanol were...

High pressure viscosity data are necessary to complement fluid characterization, but their accurate determination is always a challenge due the lack of these data. This work focuses on characterizing four alcohols (1-propanol, 2-propanol, 1-pentanol and 2-pentanol) through measurements using two different equipment: falling body viscometer vibrating wire viscometer. Both techniques can measure ...
