human renal carcinoma cells, c-Fes, siRNA, proliferation, Akt1, NFκBStudies were performed on the separation of pyridine/water solutions using pervaporation. Organic permeation experiments were performed using a silicalite-filled silicone composite membrane. Effects of feed concentration, feed temperature...
After removing methanol by evaporation under vacuum, ice-water (20 ml) was added to the residue and the pH was adjusted to 10 by adding saturated aqueous Na2CO3 solution. The dimethyl ester product precipitated out as a white solid, and was collected by filtration under suction, washed with ...
Pyridine, is a slightly yellow or colorless liquid; hygroscopic; unpleasant odor; burning taste; slightly alkaline in reaction; soluble in water, alcohol, ether, benzene, and fatty oils; specific gravity, 0.978; autoignition temperature, 482 °C. Pyridine, a tertiary amine, is a somewhat stronger...
All membranes were selective to water, but the transport mode and selectivity properties of membranes were dependent on both the character of the ion-exchange group and the ionic form of the membrane. The results obtained suggest that pervaporation of waterpyridine mixtures could be used with ...
