BENZENESULFINIC ACID SODIUM SALT Chemical Properties,Uses,Production
Chemical Properties
white crystalline powder or crystals
Uses
Benzenesulfinic Acid Sodium Salt is used reduce the adverse chemical interaction involved in the coupling of self/dual-cured composites to hydrated dentin.
General Description
Benzenesulfinic acid sodium salt when treated with alkynylselenonium salts yields (Z)-β-alkoxyvinylsulfones. It undergoes rhodium-catalyzed desulfinative coupling with aldehydes to yield ketones.
Purification Methods
Dissolve it in the minimum volume of O2 free H2O (prepared by bubbling N2 through for 2 hours) and adding O2 free EtOH (prepared as for H2O), set aside at 4o overnight under N2, filter, wash with EtOH, then Et2O and dry in vacuo. The Na salt is relatively stable to air oxidation, but is best kept under N2 in the dark. Also recrystallise it from EtOH and dry it at 120o for 4hours in a vacuum.
