The organization of 1-butanol and 1-hexanol at the air-liquid interface of aqueous, aqueous ammonium bisulfate, and sulfuric acid solutions was investigated using vibrational broad bandwidth sum frequency generation spectroscopy. There is spectroscopic evidence supporting the formation of centrosymmetric structures at the surface of pure butanol and pure hexanol. At aqueous, ammonium bisulfate,...

The suspension freeze crystallization of aqueous 1-butanol solutions, synthetic acetone-butanol-ethanol (ABE) and ABE fermentation broth was studied as a novel concentration method that requires less energy than evaporation for water removal. equimolar solutions in total molality range 0–5.05 mol/kg(water) were proven to be ideal based on the freezing point depression obtained. An solution 8 wt...

Bacillus marmarensis strain DSM 21297 is an extreme obligate alkaliphile able to grow in medium up to pH 12.5. A whole-shotgun strategy and de novo assembly led to the generation of a 4-Mbp genome of this strain. The genome features alkaliphilic adaptations and pathways for n-butanol and poly(3-hydroxybutyrate) synthesis.

Butanol (C4H10OH) has been used both to dissect the molecular targets of alcohols/general anesthetics and to implicate phospholipase D (PLD) signaling in a variety of cellular functions including neurotransmitter and hormone exocytosis. Like other primary alcohols, 1-butanol is a substrate for PLD and thereby disrupts formation of the intracellular signaling lipid phosphatidic acid. Because sec...

In the title compound, C19H30O3Si, both rings adopt a half-boat conformation. Overall, the mol-ecule approximates a U-shape as the cyclo-2-ene-1,4-dione and butyl-dimethyl-sil-yloxy substituents lie to the same side of the central cyclo-hexene ring; the methyl substituent lies to the other side of the mol-ecule. In the crystal, linear supra-molecular chains along the b axis are sustained by C-H...

The main objective of this study was assessment the performance, emissions and combustion characteristics a diesel engine using RME–1-butanol blends. In assessing process, great importance placed on evaluating stability process. Not only were typical COVIMEP indicators assessed, but also non-burnability characteristic stages: ignition delay, time 50% heat release end combustion. evaluation proc...

Phytohormone salicylic acid (SA) is a crucial component of plant-induced defense against biotrophic pathogens. Although the key players of the SA pathway are known, there are still gaps in the understanding of the molecular mechanism and the regulation of particular steps. In our previous research, we showed in Arabidopsis suspension cells that n-butanol, which specifically modulates phospholip...

Biodiesel can be produced both in homogeneous and heterogeneous ways. Heterogeneous synthesis allows to easily separate catalyst from esters. In this work, eggshells as a were used for triglyceride transesterification with 1-butanol. Response surface methodology was process optimization. It obtained that are suitable processes. A longer duration higher amount have high influence on ester yield....

Both sexes of the noctuid moths Lacanobia subjuncta (Grote & Robinson), Mamestra configurata Walker (bertha armyworm) and Xestia c-nigrum (L.) (spotted cutworm) are attracted to the combination of acetic acid and 3-methyl-1-butanol (isoamyl alcohol). A controlled-release system for use of this attractant in traps was comprised of separate polypropylene vials for each chemical, with the chemical...
