    • A process of producing a concentrated liquid biocide formulation is described. Mixed together are (a) bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 12, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1. A continuous process for producing the concentrated liquid biocide composition is provided. This process comprises continuously feeding into mixing apparatus (i) bromine and (ii) an aqueous solution of alkali metal salt of sulfamic acid; the desired product is withdrawn from the mixing apparatus at a rate sufficient to enable the continuous feeding to be maintained. Also described are methods for disinfecting surfaces and for sanitizing bodies of water using a single-feed, bromine-based biocide. These methods use concentrated liquid biocide compositions comprising biocidally active bromine as the biocide.

    • Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine in the biocidal composition as active bromine capable of providing biocidal activity.
    • 描述了生产浓缩液体杀生物剂制剂的方法。 混合在一起是(a)溴化氯或溴,和(b)具有至少约7的pH的氨基磺酸的碱金属盐的水溶液,其量使得(i)溶液的活性溴含量至少为 大约100,000ppm(wt / wt),和(ii)当使用溴时,(a)和(b)的氮与活性溴的原子比大于1,并且当使用溴氯化物时大于0.93。 在该方法中使用溴氯化物作为活性溴的来源是优选的,因为在所得含水组合物中溴溴化物的溴全部作为活性溴在溶液中得到。 换句话说,溴化氯的氯在该过程中转化为溶解的碱金属氯化物盐,从而释放杀生物组合物中的全部溴作为能够提供杀生物活性的活性溴。

    • The process involves (a) continuously forming bromine chloride from separate feed streams of bromine and chlorine by maintaining said streams under automatic feed rate control whereby the streams are continuously proportioned to come together in equimolar amounts to form bromine chloride; (b) continuously forming an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), a pH of at least 7, and an atom ratio of nitrogen to active bromine greater than 0.93:1 by continuously feeding into mixing apparatus separate feed streams of (1) bromine chloride formed in (a), and (2) an aqueous solution of alkali metal salt of sulfamic acid, under automatic feed rate control whereby the feed streams are continuously proportioned to come together in amounts that produce an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), a pH of at least 7, and an atom ratio of nitrogen to active bromine from (1) and (2) greater than 0.93:1; and, (c) withdrawing said aqueous product from said mixing apparatus at a rate sufficient to enable the continuous feeding in (a) and (b) to be maintained.
