Synthesis, Characterization and Performance of a New Type of Alkylene Triphenyl Double Quaternary Phosphonium Salt ()
Abstract
ByBimolecular
Nucleophilic Substitution, four new types of alkylene triphenyl double
quaternary phosphonium salt were synthesized respectively by using
triphenylphosphine, 1,3-dibromopropane, 1,6-dibromohexane,1,10-dibromo- decane, 1,12-dibromododecane as raw materials and using DMAC as
the solvent, under a certain temperature and reac- tion time. The productivity is 58% - 83%. The molecular structures of
the products were characterized by IR, NMR and elemental analysis. The sterilizing effect of 1,6-hexylidene triphenyl double
phosphonium bromide(HTDPB)
and 1,12- dodecylidene triphenyl double phosphonium bromide(DoTDPB) was
evaluated by using extinct dilution method.The experimental result shows that the sterilizing effect of DoTDPB is better
than the effect of HTDPB under the same drug concentration and contact time.
When the concentration of DoTDPB was 20 mg/L and the contact time was 0.5 h,
the sterilizing rate of DoTDPB used to kill saprophytic
bacteria (TGB), sulfate-reducing
bacteria (SRB) and iron
bacteria (IB) was 95.56%, 84% and 99.58% respectively.
