Focal conduction block in n-hexane polyneuropathy

Muscle & Nerve, 1998
A 19-year-old man with an asymptomatic history of recreational gasoline vapor inhalation presented with subacute progressive quadriparesis. For 2 weeks, he had intensely inhaled Coleman fuel oil vapor, which contains n-hexane. Nerve conduction studies including near-nerve needle stimulation showed focal conduction block in the bilateral median and ...

Method for the simultaneous quantification of n-hexane metabolites: application to n-hexane metabolism determination

Human & Experimental Toxicology, 1996
1 The described analytical procedure permits the simultaneous determination of the main n-hexane meta bolites in urine. 2-Hexanone, 2-hexanol, 2, 5-hexanediol and 2, 5-hexanedione, were chosen to dose the rats used in this study. All urine samples were collected and analysed on a daily basis, before and after acidic hydrolysis (pH 0.1) by GC/MS.

Avalanche breakdown in n-hexane

Journal of Physics D: Applied Physics, 1979
Time lags to breakdown in n-hexane have been measured in high over-voltages, using approximately 100 ns width rectangular pulses. At a constant field, the time lags are divided into two types, N and B, at a 'critical distance' d. Above dc, Laue plots have almost similar kinked-line characteristics; below dc, a straight line is obtained.

Polyneuropathy Due to n-Hexane

Archives of Internal Medicine, 1976
In 25 years, at least eight of 50 total exposed employees in a small plant developed a mild neuropathy. Studies of urine or blood for lead, arsenic, mercury, cadmium, thallium, and antimony revealed no sign of toxic agents, but the atmosphere in one room contained toxic levels of n-hexane. The source was the glue used in the plant. Serum cholinesterase

Aromatization of n-hexane by platinum-containing molecular sieves II. n-Hexane reactivity

Journal of Catalysis, 1992
Abstract Pt/KL, Pt/BaKL, Pt/KBaKL, Pt/NaY, Pt/CsNaY, Pt/NaFAU(C), Pt/hex, Pt/SSZ-24, Pt/silica, and Pt/carbon were tested as catalysts for the aromatization of n-hexane at 460–510°C and atmospheric total pressure in order to study the influence of Pt cluster size and support acidity/basicity, microstructure, and chemical composition on activity and ...

Thermodynamic properties of n-hexane

International Journal of Thermophysics, 1988
Specific volumes and isobaric heat capacity measurements are reported for n-hexane. The measurements were made in the liquid and vapor phases at temperatures from the triple point and also cover a wide region around the critical point. The thermal, caloric, and acoustic data from our own investigation as well as those of a number of other authors are ...

n-Hexane Polyneuropathy in Japan: A Review of n-Hexane Poisoning and Its Preventive Measures

Environmental Research, 1993
n-Hexane is used in industry as a solvent for adhesive, dry cleaning, and vegetable oil extraction. In 1963, the first case of severe polyneuropathy suspected to be caused by n-hexane was referred to us. Case studies, animal experiments, and field surveys on n-hexane poisoning were conducted, and preventive measures like threshold limit value revision ...

Electric Breakdown in n-Hexane

Nature, 1965
ALTHOUGH the phenomena of breakdown and conduction in liquid insulants have received considerable attention, the degree of understanding that has been achieved is limited, a fact illustrated by the co-existence of several widely differing models for the breakdown process. The main reasons for this failure are the absence of a satisfactory theory of the

Photoemission into Liquid n-Hexane

Nature, 1961
RECENT measurements of conduction1 and of ion transit time2,3 in liquid n-hexane have made use of the fact that electrons can be released into the liquid by the incidence of ultra-violet illuminations on the cathode surface. These measurements have been interpreted with the assumption that the ultra-violet light can be passed through the liquid to the ...

Electric breakdown in n-hexane

Annual Report 1960 Conference on Electrical Insulation, 1960
Electric breakdown and conduction in organic liquids has been the subject of reintensified investigation in recent years. But even in highly purified test liquids such as n-hexane the experimental evidence is still subject to continuous alteration and improvement.
