Navy fuel interactions with additives. Phase I. An investigation of side effects from a commercial biocide. Research and development report

Potentially detrimental side effects of adding an organoboron type of biocide to Navy distillate fuels have been investigated. There were no significant differences in such properties as interfacial tension, demulsibility, accelerated storage stability, acidity (neutralization number), and flash point temperature as a result of adding the biocide, when these properties were measured immediately after blending and also after 16 weeks of storage at 75/sup 0/F (24/sup 0/C) or at 110/sup 0/F (43/sup 0/C). Appreciable portions of biocide were leached out of the fuel by water present. No consistent major effects on the operation of a filter/separator were evident, but a reduction of the water content of the effluent fuel was associated with the presence of the biocide. (GRA)
