    • Phosphorus-based compositions useful as biocides for the control of a broad spectrum of harmful micoorganisms are disclosed. The compositions contain at least one compound of the general formula(RO).sub.2 P(O)CXYZwherein R is H, a C.sub.1-12 aliphatic hydrocarbon radical or a phenyl radical, X is H or halogen, Y is halogen, and Z is a substitutent selected from the group consisting of COOH, CN, COOR and CONR.sub.2, with the proviso that X and Y cannot both be C1. The effective concentrations of the biocides vary according to the specific system, generally being in the range of between 0.1 to 5000 parts per million of substrate. The compositions may be employed alone or in the form of mixtures with other known compatible active agents. The compositions show high biocidal activity against various microorganisms in comparison with known biocides.
    • 公开了用作控制广谱有害微生物的杀生物剂的基于磷的组合物。 组合物含有至少一种通式为(RO)2P(O)CXYZ的化合物,其中R为H,C1-12脂族烃基或苯基,X为H或卤素,Y为卤素,Z为 选自COOH,CN,COOR和CONR2的取代基,条件是X和Y不能都是C1。 杀菌剂的有效浓度根据具体系统而变化,通常在每百万基质的0.1至5000份之间的范围内。 组合物可以单独使用或以其它已知的相容活性剂的混合物的形式使用。 与已知的杀生物剂相比,该组合物对各种微生物显示出高杀生物活性。
