Equilibrium of Hydrogen + Cyclopentane and Carbon Dioxide + Cyclopentane Binary Hydrates

Journal of Chemical & Engineering Data, 2008
Cyclopentane (CP) forms sII hydrates, in which CP only occupies the large cavities. Small gas molecules such as hydrogen and carbon dioxide can be encaged in the small cavities. However, there are no reported data on the equilibrium conditions of CP + H2 and CP + CO2 binary hydrates, which are essential to developing CO2 capturing or H2 enriching ...

Hydrate Equilibrium Conditions for Cyclopentane and a Quaternary Cyclopentane-Rich Mixture

Journal of Chemical & Engineering Data, 2001
Experimental data on hydrate formation of cyclopentane and a 98.40 mass % purity cyclopentane mixture containing three impurities (0.48 mass % pentane, 0.48 mass % 2-methyl butane, and 0.72 mass % 2-methyl propane) in water were measured. The measurements were carried out in a transparent sapphire cell (100-cm3 effective volume) by applying a pressure ...

The pure rotational Raman spectrum of cyclopentane-d0 and cyclopentane-d10

Journal of Molecular Spectroscopy, 1963
The pure rotational Raman spectra of C5H10 and C5D10 were photographed under high dispersion in the 13th order of a 300 grooves/mm plane grating using the line Hg 4358 A for excitation. The spectra are quite weak and diffuse and resemble that of a symmetric top rotator.

Infrared Spectra of Crystalline Cyclopentane and Cyclopentane-d10

The Journal of Chemical Physics, 1969
Infrared spectra of crystalline cyclopentane and cyclopentane-d10 have been measured at different temperatures between 4000 and 200 cm−1. Spectroscopic evidence shows that form I (− 120°C) and form II (− 140°C) have the same degree of disorder as the liquid. In the ordered crystal form III (− 180°C) the molecule has a rigid bent conformation.

Appliance Rigid Foams Blown with Cyclopentane and Cyclopentane/Isopentane Blends

Journal of Cellular Plastics, 2000
Since CFC 11 was eliminated from use in rigid foams in the mid 1990s, the blowing agent of choice in North America has primarily been HCFC 141b. In the USA, we are now faced with the phase-out of HCFC 141b by the year 2003. The blowing agent that will replace HCFC 141b must be non-ozone depleting and should also have low thermal conductivity and a low ...

Cyclopentane Peptide Nucleic Acids

2013
Incorporating a cyclopentane ring into the two-carbon unit of a peptide nucleic acid backbone increases its binding affinity to complementary nucleic acid sequences. This approach is a general method to improve binding and can be applied at either purine or pyrimidine bases.
