Ultrasonic studies of n-hexane-perfluoro n-hexane mixtures

Molecular Physics, 1980
Ultrasonic absorption and velocity measurements over the frequency range 1 to 10 MHz at 303 K on mixtures of n-hexane and perfluoro-n-hexane confirm the existence of a rotational isomeric relaxation in the perfluoro-compound, and give evidence of a structural relaxation in the liquid mixtures.

Structure of liquid n-hexane

The Journal of Chemical Physics, 2009
The structure of deuterated liquid n-hexane has been investigated at room temperature by neutron diffraction and molecular dynamics simulations. By carrying out a careful analysis of the measurements, experimental data were obtained in very good agreement with the simulated data.

n‐Hexane Polyneuropathy†

Psychiatry and Clinical Neurosciences, 1969
SummaryNinety‐three cases of intoxication polyneuropathy occured among household workers exposed to excess concentrations of the n‐hexane vapor over several months or more. The chief manifestation was polyneuropathy of glove‐and‐stocking type. According to the mode of involvement, they were classified into three groups: sensory polyneuropathy 53 cases,

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.

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.

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.

Excess second virial coefficients for (benzene + n-hexane) and (cyclohexane + n-hexane)

The Journal of Chemical Thermodynamics, 1983
Abstract For (benzene + n -hexane) and (cyclohexane + n -hexane) measurements are reported of the pressure change on mixing and the excess second virial coefficient ϵ 12 calculated therefrom. Measurements at the following temperatures are reported: 298.15, 323.15, 373.15, and 398.15 K.

N-hexane maculopathy in industrial workers

Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1978
A neuro-ophthalmologic examination, including fluorescein angiography and colour discrimination tests, was made of 15 workers (age range 30--65 years, mean 45.8 years) exposed to n-hexane (range of exposure 5--21 years) during vegetable oil extracting and adhesive bandage manufacturing.

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 ...
