The solubility of sulfapyridine (SP) in ethanol+water cosolvent mixtures was measured at temperatures from 293.15 to 313.15K in all the polarity range provided by aqueous mixtures conformed by ethanol and water (solubility parameter, delta mix=26.5-47.8MPa 1/2). The solubility was maximal in the...
Electrolytic deposition was carried out using 0.5 M Mg(NO3)2 in ethanol and water, according to a method developed by Hashaikeh and Szpunar30. When an adequately high potential field is applied across two electrodes in an aqueous solution of Mg(NO3)2, the dissociation of Mg(NO3)2 into...
(AF1 Dual, Elveflow) and run by using ESI elveflow software interface. After washing the electrochemical cell, O-rings and pressure components were dried with N2gas blow. The devices once mounted on the cell were wet thoroughly with ethanol, ethanol–water (50 : 50), and then ...
Name two physical properties that could be used to distinguish between water and ethanol. Why is the solubility of butane 6.1 mg / 100 g water, yet hexane is immiscible in water? Why are most phenols only slightly soluble in water? How do differences in polarity affect solubility? Briefly...
Examples include ethanol, acetate, lactate, and butyrate. Fermentative organisms are very important industrially and are used to make many different types of food products. The different metabolic end products produced by each specific bacterial species are responsible for the different tastes and ...

摘要:Chemical cleaning of fouled hollow-fiber polyvinyl chloride (PVC) membrane with the consecutive use of NaOH and ethanol during ultrafiltration of river water was investigated in the study. Results showed that through the chemical cleaning with 1% NaOH for 30 min, a negative cleaning efficiency...
In the conditions of resistance of the device increases and decreases abruptly under the same electrical polarity. The abrupt increase in resistance near zero bias, just as the case at low RH, can be attributed to the rup- ture of the conductive filament induced by H+ ions drifting. The ...
An ink of 20% Pt/C was prepared by the addition 10 mg of 20% Pt/C or 20% Ir/C (Premetek, USA) into 1.96 mL of 50% ethanol solution containing 0.04 mL 5% Nafion binder solution (Sigma-Aldrich, USA). The ink was then loaded onto substrate and dried under vacuum at 40...
