Sulfide Stability Tests The following biocides were tested for stability in the presence of sulfide: pentane-1,5-dial (glutaraldehyde, glut); tetrakis(hydroxymethyl)phosphonium sulfate (THPS); N-alkyl-N,N-dimethyl-N- benzylammonium chloride (ADBAC); didecyl dimethyl ammonium chloride (DDAC...

... and tetrakis hydroxymethyl phosphonium sulfate (THPS).can provide synergistic biocidal performance against commonly found oilfield bacteria. Whilst 1,3-Dimethylol-5,5- dimethylhydantoin can be considered a functional equivalent to biocides such as dimethyl oxazolidine, its controlled release profile appears...

... phosphonium compound, tetrakishydroxymethyl phosphonium sulfate (THPS), was disclosed. Unlike traditional quaternary biocides, which have at least one long alkyl chain moiety, THPS is a small, symmetrical molecule. The general structures of ADBAC, DDAC and THPS are shown in Figure 1. THPS has been used...
