Uses five] propylene glycol methyl ether (107-98-2) is widely used in paints and cleaning agents. Particular application as an active solvent of water-based paint; reactive solvent and solvent-based printing inks of a coupling agent; and ballpoint pen ink solvent; household and industrial cleaners, rust and hard surface cleaners coupling agent and a solvent; Solvent agricultural pesticides; and propylene glycol n-butyl ether mixed formulations for glass cleaner. [Six] use as a solvent; dispersants or diluents for paint; ink; printing; pesticides; cellulose; acrylates and other industries. Also be used as fuel antifreeze agent; cleaning agent; extraction agent; non-ferrous metal processing agents. Also used as a raw material for organic synthesis. In the event of sulfonation reversible, enter the location and condition of the outside world is very relevant. At low temperatures, the first port hydrogen substituted propylene glycol methyl ether use, when the temperature rises, and then transferred to the more stable p-position, which results show that α- naphthalenesulfonic acid generation is kinetically controlled, and β- naphthyl sulfonic acid generation is controlled by the thermodynamics. The above-mentioned phenomenon shows that the price of propylene glycol methyl ether, and naphthalene nitration, halogenation as sales glycol methyl ether, naphthalenesulfonic acid generating α- β- naphthalenesulfonic acid generated is lower than the activation energy, provides less energy at low temperatures, so produce mainly α - naphthalene sulfonic acid. However, the sulfonation reaction is reversible, due to, α- sulfo group and isobutyl ring α-H in a parallel position, hindered larger glycol methyl ether, unstable, as the reaction temperature increases, α- naphthalene sulfonic acid increased reverse rate α- sulfonation reaction will gradually increase; in addition, the temperature rise is also conducive to providing the activation energy required for the reaction β- sulfonation, the reaction rate is also increased so that, β- sulfo and hydrogen from adjacent large, good stability, and its reverse reaction rate is very slow, so α- naphthalene sulfonic acid gradually transformed into β- naphthalene sulfonic acid.
