Excess volumes for (2-methylbutan-2-ol + n-heptane) and for (cyclopentanol + n-heptane)

The Journal of Chemical Thermodynamics, 1985
Abstract Excess volumes measured at 298.15 K in a successive-dilution dilatometer are reported for binary mixtures of (2-methylbutan-2-ol + n -heptane) and of (cyclopentanol + n -heptane). The 2-methylbutan-2-ol mixture exhibits positive excess volumes over the whole mole-fraction range.

Calculation of the viscosity of n-heptane-methanol solutions at low n-heptane concentrations

Russian Journal of Physical Chemistry, 2007
The molar heat capacity C p of the methanol-n-heptane system was measured at low concentrations of n-heptane and 298.15 K. The dynamic viscosity η of the system at 298.15 K was calculated from data on the molar heat capacity of methanol-n-heptane solutions within the framework of the Flory theory and ...

Whole-cell double oxidation of n-heptane

Journal of Biotechnology, 2014
Biocascades allow one-pot synthesis of chemical building blocks omitting purification of reaction intermediates and expenses for downstream processing. Here we show the first whole cell double oxidation of n-heptane to produce chiral alcohols and heptanones.

Electrodilatometry 3: Cyclohexanol in n-heptane

Journal of Molecular Liquids, 2000
Abstract The new technique of electrodilatometry, known to be very sensitive to H-bonded systems, has been used to study a binary mixtures of cyclohexanol with n-heptane at 298K over a concentration range 0.400-1.00 mole fraction (F). The magnitude of R varies from 0.711×10−18 m2/V2 (at F=0.400) to 20.8×10−18 m2/V2 (at F=1.00).

EXCESS ENTHALPIES OF 3-METH YLPHENOL - n - HEPTANE, 3-METH YLPHENOL - PHENOL -n- HEPTANE AND 3-METHYLPHENOL- 1-HEXANOL-n-HEPTANE AT 318·15 K

Chemical Engineering Communications, 1997
Excess molar enthalpies HE for two ternary systems, 3-methylphenol-phenol-n-heptane and 3-melhylphenol-1-hexanol-n-heptane and a constituent binary 3-methylphenol-n-heptane have been measured with Calvet-type microcalorimeter at 318·15 K. For predicting ternary excess enthalpies, the modified Redlich-Kister equation was used. It has been shown that the

High pressure pyrolysis of n-heptane

Journal of Analytical and Applied Pyrolysis, 2009
Abstract Pyrolysis of n -heptane was investigated in a tubular reactor in the temperature range of 793–953 K and pressure range of 0.1–2.93 MPa. At all conditions, the main products were methane, ethylene, ethane, propylene, 1-butene, 1-pentene and 1-hexene. With an increase in pressure, the selectivities of hydrogen, methane, ethylene and propylene

Skeletal Mechanisms for n-Heptane Combustion

Volume 1: Combustion and Fuels, Education, 2006
In order to predict with CFD codes the ignition of kerosene including pollution formation it is necessary to develop a reduced mechanism, which can be incorporated into the code and applied without dramatically increasing the turn-around time. The practical global chemical schemes, which reflect the combustion properties for large a range of parameters

The spontaneous combustion of n-heptane

Combustion and Flame, 1973
The spontaneous combustion of n -heptane has been studied in a static system between 240 and 428°C. During reaction the changes in both pressure and temperature were followed; the latter proved the more useful method of discriminating between the various modes of combustion.
