The feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (TOMAC) as an extractant, was studied. The diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. The effect of initial acid concentration in t...

The crystal structures of the tri- and tetrahydrate of tin tetrachloride, viz. diaquatetrachlorotin(IV) monohydrate, [SnCl(4)(H(2)O)(2)].H(2)O, and diaquatetrachlorotin(IV) dihydrate, [SnCl(4)(H(2)O)(2)].2H(2)O, are reported and shown to contain the cis-[SnCl(4)(H(2)O)(2)] species and water molecules in both cases. The trihydrate contains chains of the tin species linked by a single hydrogen-bo...

Health  Toxic by inhalation, ingestion and dermal exposure  Inhalation and ingestion may cause a reduced conscious level, sickness, headache, dizziness, vomiting, stomach pain, diarrhoea and difficulties with breathing  Ingestion and inhalation may also cause liver and kidney damage, which in severe cases can lead to coma and death  Skin or eye contact can cause irritation  Carbon tetrachl...

The effects of an oral administration of carbon tetrachloride on various liver microsomal and supernatant components were studied 1hr. and 2hr. after dosing. The modifications of such early changes resulting from a concomitant administration of promethazine together with the carbon tetrachloride were also investigated. The microsomal components studied were: cytochromes P-450 and b(5); inorgani...

The structure of solid zirconium tetrachloride is known from X-ray studies[l] to consist of extended chains of distorted octahedra with two bridging chlorine atoms between adjacent zirconium atoms. Although the unit cell possesses a center of symmetry, the two pairs of bridging chlorine atoms attached to a given zirconium atom are not trans to each other. The factor group symmetry thus is C2h w...

BACKGROUND Herbal supplements are widely used in the treatment of various liver disases, but some of them may also induce liver injuries. Regarding the infuence of thyme and its constituents on the liver, conflicting results have been reported in the literature. The objective of this study was to examine the influence of two commonly used pharmaceutical formulations containing thyme (Thymus vul...
