Vibrational spectra of liquid 1-propanol

Journal of Molecular Structure, 2008
Abstract The spectrum of the complex refractive index in the 12,000–100 cm −1 region was determined for liquid Propan-1-ol from transmission studies. In the MIR region, very thin layers with thicknesses of a few micrometers had to be used to obtain reliable data. Liquid Propan-1-ol is totally associated via hydrogen bonds.

1-Propanol hydrate by IR spectroscopy

Canadian Journal of Chemistry, 2002
The mid-IR attenuated total reflectance (mid-IR–ATR) spectra of a series of 1-propanol and water mixtures were obtained. Factor analysis (FA) applied to spectra gave the spectra of three principal species and their abundance: pure water, pure propanol, and a 1-propanol hydrate (1:1).

Dielectric properties of electrolytes in 1-propanol

Journal of Solution Chemistry, 1986
The dielectric properties of LiCl, CaCl2·2H2O, Ca(NO3)2·4H2O, Al(NO3)3·9H2O in 1-propanol solutions have been investigated using the dielectric time domain spectroscopy technique. The dielectric spectrum of 1-propanol in the 50 MHz-5GHz interval can be described by a single relaxation time.

Infrared dispersion of liquid 1-propanol

Journal of Non-Crystalline Solids, 2007
Abstract The spectra of the real and imaginary components of the complex refractive index were determined for liquid n -propanol using a new method, which takes into account the dispersion of the refractive index in the visible range and requires integration over the entire absorption range in the near infrared, mid infrared and far infrared ...

Reactivity Consequences of Conformational Isomerism in 1-Propanol

The Journal of Physical Chemistry A, 2019
We present an electronic-structure study of the O(3P) reaction with all 5 conformers of 1-propanol. Calculation of the potential energy profile along 37 hydrogen-abstraction reaction pathways reveals that exclusive consideration of the popular all- anti conformer fails to capture essential details of 1-propanol's reactivity.

Effect of Boiling on the Radiolysis of 1-Propanol

High Energy Chemistry, 2019
The radiolysis of 1-propanol without heating and in a boiling state under the action of accelerated (8-MeV electrons) was investigated. At room temperature, aldehydes dominated among molecular products. Unlike γ-radiolysis, monohydric alcohols were the second most important fraction.

Preparation of (+)- and (-)-2,3-dibromo-1-propanol

Journal of Chemical & Engineering Data, 1982
The enantiomers of 2,3-dibromo-1-propanol were obtained by diazotization of the diastereomeric d-tartrate salts of 2,3-dibromopropylamine. The products of the reaction contained approximately 13% of the secondary alcohol 1,3-dibromo-2-propanol which was separated by either column chromatography on silica gel or preparative GLC to obtain the primary ...

Calorimetric study of the interaction of lysozyme with aqueous 1-propanol

Biochemistry, 1981
The enthalpies of transfer of hen egg white lysozyme from water to aqueous solutions of 1-propanol were determined by isothermal flow calorimetry at 10, 17, 25, and 40 degrees C in 0.04 M, pH 2 glycine buffer. Alcohol concentrations up to 3.4 M were employed.

Metabolic engineering of Escherichia coli for the production of 1-propanol

Metabolic Engineering, 2012
An engineered Escherichia coli strain that produces 1-propanol under aerobic condition was developed based on an L-threonine-overproducing E. coli strain. First, a feedback resistant ilvA gene encoding threonine dehydratase was introduced and the competing metabolic pathway genes were deleted.
