12 Αυγ 2016 · 1. Chemical Properties (Acid-Base) One of the oldest (and still widely used) methods for natural product isolation is to modify the pH, and thus the water-solubility, of acidic and basic molecules in the mixture. This is because certain basic and acidic molecules can easily be converted into salts, which greatly increases their water solubility.
9 Ιουν 2023 · Toluene is used: as a solvent in paints, varnishes, corrosion inhibitors; as an ingredient in gels, sprays, hair dyes, detergents and disinfectants; in the production of medicines, dyes, rubber, resins; as a substrate to synthesise common chemicals: trinitrotoluene, benzoic acid, toluene diisocyanate; for the production of explosives, primarily ...
