Because of the small separation by the pervaporation PV technique; the pore size, the diffusion Aniline Case Studies of some molecules with latter uses a liquid feed and a vacuum on the permeate different sizes and adsorption strengths inside the side of the membrane.

The PV technique has a greater zeolite crystals differ Aniline Case Studies orders of magnitude.

Conventionally, distillation can be used, but the method is not feasible Zeolite-filled NaAlg and pure NaAlg membranes at azeotropic compositions of the mixture. The water— NaAlg 3 g was dissolved in 80 mL of water with ACN mixture forms an azeotrope at the water com- continuous stirring. Zeolite 0. To tackle this issue, we de- mL of water, and the Aniline Case Studies was sonicated for about veloped six membranes, namely, plain sodium algi- 30 min.

Samples were then used as pigments through blending them with acrylic paint and applied on the surface of carbon steel panels. Corrosion was evaluated for coating of carbon steel panels through full immersion test up to standard ASTMG Mass loss was calculated after they have been exposed in acidic media. A digital camera was also used for monitoring corrosion visually on the surface of carbon steel specimens. The results revealed that acrylic paint pigmented by PANI-SiO2 composite was more efficient in corrosion protection for carbon steel compared with the other synthesized pigments.

GUT, I. Thesedifferencesbetweenin vitro and in viva studiesindicate that observation under in vivo conditions is essentialfor correct understandingand interpretation of in vitro results. A singleadministration of diphenylhydantoin DPH to adult rats was found to stimulate hexobarbital biotransformation by liver 85OOgfraction in vitro Kato et al. In vitro hexobarbital biotransformation was also increased by DPH treatment of newborn rats. DPH was reported to increasethe liver to the body weight ratio in nonpregnant female rats Gabler and Falace, The liver to body weight ratio was also increased in newborn rats by DPH Eling et at. DPH was reported to have no effect on liver weight in adult male rats Platt and Cockrill, In the present experiments a significant increase of liver to body weight ratio of adult male rats was consistently observed after DPH treatment. This observation suggestedthat, despite finding no significant DPH influence on aniline metabolism in vitro, such an effect might exist in vivo. Stimulation of in viuo metabolism is important from the pharmacological and toxicological points of view, Therefore, the purpose of this paper is to determine DPH effects on the biotransformation of hexobarbital and aniline in vitro and in uiuo in adult male rats.
