Propylene glycol, also known as 1,2-Propylene glycol, is a colorless, transparent, viscous liquid with hygroscopic properties. It can react with acids to form esters and with alkyl sulfates or halogenated hydrocarbons to form ethers. It is miscible with water, acetone, ethyl acetate, and chlorof...
Polymers and drugs are dissolved in a polar, water-miscible solvent such as acetone, acetonitrile, ethanol, or methanol. The solution is then poured in a controlled manner (i.e. drop-by-drop addition) into an aqueous solution with surfactant. Nanoparticles are formed instantaneously by rapid ...
If you were to use the solvent acetone for an aldol reaction, would this solvent be a good or bad candidate? Explain why or why not. Are water and diethyl ether miscible or immiscible? Explain. List the ways (operations) that can help make a substance dissolve faster in a solvent. Why ...
Water:Water is a covalent chemical compound which has the formula H2O. It is a colorless and odorless liquid at room temperature and pressure and it boils at 373 Kelvin and melts at 273 Kelvin.Answer and Explanation: Viroids are soluble in water. This is because viroids are made up of RNA...

which is a key enzyme in gastric acid production. It must have an inhibitory effect on basal gastric acid and stress-induced gastric acid secretion caused by stimulation. Lansoprazole is suitable for gastric ulcer, duodenal ulcer, erosive gastroesophageal reflux disease, Helicobacter pylori, and Zoll...
Can I use acetone instead of xylene? Acetone can beused to take off nail polish, paints or even lacquers. Xylene can be used for making histological preparations, and certain plastics. It can also be used as a solvent and cleaning agent. ...
per cent of an organic solvent selected from acetonitrile, t-butanol, tetrahydrofuran, dioxane and acetone until at least 2 wt. per cent of the monomers have polymerized, and thereafter adding during the polymerization one or more quaternary ammonium monomers as referred to above (which may be ...
It is not necessary that the solvent for the reactants consist entirely of water, however, since other water miscible solvents such as, alcohol, acetone, Cellosolve, etc. may be employed in part if desired. As it is known that acyl dicyandiamides will hydrolyze to the corresponding acyl ...
The un-irradiated and thus uncured zones of the coating are removed. This may, for example, proceed by rinsing with organic solvents, such as ketones, for example, acetone, alcohols, for example, isopropanol or esters, for example butyl acetate or ethyl acetate. If water-soluble binders have...
