alkanes c2 c4/seizures

Male Sprague Dawley rats were exposed to inhalation of n-C9 to n-C13 alkanes close to air saturation at 20 degrees (4438, 1369, 442, 142 and 41 p.p.m., respectively) for 8 hours and observed for the following 14 days. In addition, exposure to higher and lower concentrations of n-C9 was performed.

Some inhaled compounds cause convulsions. To better appreciate the physical basis for this property, we correlated the partial pressures that produced convulsions in rats with the lipophilicity (nonpolarity) and hydrophilicity (polarity) of 45 compounds: 3 n-alkanes, 18 n-haloalkanes, 3 halogenated

We examined the anesthetic and convulsant properties of 16 unfluorinated to completely fluorinated aromatic compounds, having six to nine carbon atoms (e.g., benzene to 1,3,5-tris(trifluoromethyl)benzene), and four cycloalkanes (cyclopentane to cyclooctane). Benzene, fluorobenzene, toluene,
