N-Hexane Neuropathy

New England Journal of Medicine, 1971
Abstract In three adult cabinet finishers weakness and sensory loss developed as a result of prolonged and intense exposure to an industrial solvent. After leaving this employment, they improved. Analysis of the immediate environment and solvent revealed that each worker had an oral, respiratory and dermal contact with toxic levels of n-hexane ...

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 ...

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.

Particles and pulses in n-hexane

Journal of Electrostatics, 1979
Abstract By experimental observation the persistent controversy about the order of charge carried by minute natural particles in a liquid dielectric is resolved. The work reported earlier has been extended, by use of the on-line transient recorder in a dual channel mode, to provide a clear demonstration that the fempto-Coulomb pulses of conduction ...

The photochemical sulphoxidation of n-hexane

Tetrahedron, 1965
Abstract The photochemical sulphoxidation of n-hexane in the presence of acetic anhydride giving hexanesulphonic acid has been examined. A maximum yield of 26% is obtained when the sulphoxidation is carried out with a molar ratio of n-hexane:acetic anhydride of 19:1. An increase in the reaction temperature of 28° serves to increase the yield, and for

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 ...

THE RADIOLYSIS OF LIQUID n-HEXANE

The Journal of Physical Chemistry, 1960
The continuous decrease in hydrogen gas yield during the radiolysis of n- hexane is attributable to the addition of hydrogen atoms to the hexenes concurrently being produced. Unsaturation in the C/sub 7/--C/sub 12/ products arises from the addition reaction of alkyl plus alkenyl radicals.

Photoinduced conduction in n-hexane

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1969, 1969
The conductivity of liquid n-hexane can be increased by photoionizing the liquid itself or by photostimulating an immersed cathode. In particular, the latter method has been used to measure the mobility of negative charge carriers in the liquid. Although photoelectrons were taken to be injected at the cathode surface, the mobility values have been ...

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 ...
