Synthesis and characteristic of two new types of quaternary phosphonium salts

Two new types of quaternary phosphonium salts (BHP - 1, BHP - 2) with the function of sterilization - inhibition were synthesized. The structures of the products had been identified by IR. It was demonstrated that these types of inhibitors suppressed the growth of SRB and inhibited the development of Microbiologically Induced Corrosion (MIC). The inhibition efficiency and sterilization efficiency of the products in comparison with the ones used in industries were evaluated by weight loss method and Maximum Probable Number. The results showed that the sterilization efficiency and inhibition efficiency of BHP - 1 were the best of all. The sterilization and inhibition performances of BHP - 1 and BHP - 2 were all better than those of Ben Zalkonium Bromide Solution which was used widely in industry.
