Raman spectra of n-pentane, n-hexane, and n-octadecane: experimental and density functional theory (DFT) study

Laser physics, 2019
We carried out a density functional theory (DFT) modeling of the stable conformations of n-pentane (C5H12), n-hexane (C6H14), and n-octadecane (C18H38) as well as their Raman spectra.

Toxic polyneuropathy due to n-hexane

Journal of the Neurological Sciences, 1980
Three women developed a predominantly motor polyneuropathy following industrial exposure to an adhesive agent containing 80.4% of n-hexane as a volatile substance. Histological and electron-microscopic studies were carried out on sural nerve and on soleus muscle.

Investigating the effect of n-hexane as solvent on waste cooking oil conversion to biodiesel using CaO on a new support as catalyst

Measurement, 2019
In this study, CaO/scoria (a kind of ignition rock) was used as catalyst of transesterification reaction. We have tried to reduce production costs of biodiesel in different ways.

Neuropathy in n-hexane poisoning

S.S. Korsakov Journal of Neurology and Psychiatry
N-Hexane is a solvent widely used in manufacturing as a cleaner, degreaser and component of rubber cement. Chronic exposure to n-hexane either through contact with unprotected skin or inhalation can lead to the development of clinical symptoms and electrophysiological changes similar to those of inflammatory demyelinating polyneuropathy which requires ...

n-Hexane induces Parkinsonism in rodents

Brain Research, 1990
A case of human parkinsonism, due to n-hexane exposure, was recently described. On the basis of this observation, we treated mice and rats with n-hexane and its principle toxic metabolite 2,5-hexanedione. The mice underwent a chronic treatment intraperitoneum, the rats were treated stereotaxically into the substantia nigra.

Preparation of mesoporous mordenite for the hydroisomerization of n-hexane

Catalysis communications, 2019
A mesoporous mordenite (MOR) zeolite was prepared from a commercially available MOR sample by a sequential acid-alkaline-acid post-treatment. The latter was used as support of Pt to prepare a bifunctional Pt/H-MOR catalyst for the hydroisomerization of n-

n‐Hexane‐induced parkinsonism: Pathogenetic hypotheses

Movement Disorders, 1995
Abstractn‐Hexane, similar hydrocarbons, and derivatives are common environmental pollutants and by‐products of lipid peroxidation, and they may have a nigrotoxic effect like that of 1‐methyl‐4‐phenyl‐1, 2, 3, 6‐tetrahydropyridine. This report describes our second case of parkinsonism in a subject exposed to n‐hexane.

The effect of alternative solvents to n-hexane on the green extraction of Litsea cubeba kernel oils as new oil sources

Industrial crops and products (Print), 2018
Litsea cubeba (LC) is an indigenous industrial crop in China with fruits possessing interesting essential oil content of 3-5%, which production leads to a large number of kernels as wastes.

Poor metabolization of n-hexane in Parkinson's disease

Journal of Neurology, 2003
Although genomic screening studies have identified several genes associated with Parkinson's disease (PD), there is evidence that environmental factors are also involved in the pathogenesis of the disease and that hydrocarbon-solvents may be one of them. The genetic component is less evident in late-onset PD. To assess whether age and PD may affect the
