  The invention includes convenient methods of preparing: (1) highly concentrated liquid bromine-containing biocidal solutions, (2) highly concentrated mixed halogen liquid bromine and chlorine-containing biocidal solutions, and (3) high-activity bromine-containing biocidal solids, all having excellent physical and chemical stability. One method yields solutions that have concentrations of bromine in excess of 18% as Br 2 (8% as Cl 2 ) in which the mole ratio of hydroxide ion to hydrogen ion source is at least 1.9:1. Another method employs elemental bromine in conjunction with a solid organic or inorganic halogenating agent to yield halogen solutions at concentrations greater than 22.9% as Br 2 (10.2% as Cl 2 ). This method can be performed under conditions that exceed the solubility of the active ingredient such that it crystallizes and is recovered as a hydrated or anhydrous salt in good yield.

  该发明包括方便的制备方法：(1)高浓度液体溴含生物杀菌溶液，(2)高浓度混合卤素液体溴和氯含生物杀菌溶液，以及(3)高活性溴含生物杀菌固体，所有这些溶液具有优异的物理和化学稳定性。一种方法产生的溶液中，溴的浓度超过18%作为Br2（氯的浓度为8%），其中氢氧根离子与氢离子源的摩尔比至少为1.9:1。另一种方法利用元素溴与固体有机或无机卤化剂结合，产生浓度超过22.9%作为Br2（氯的浓度为10.2%）的卤素溶液。这种方法可以在超过活性成分溶解度的条件下进行，使其结晶并以水合盐或无水盐的形式高产得到。

One method yields solutions that have concentrations of bromine in excess of 18% as Br2 (8% as C12) in which the mole ratio of hydroxide ion to hydrogen ion source is at least 1.9: 1. Another method employs elemental bromine in conjunction with a solid organic or inorganic halogenating agent to yield halogen solutions at concentrations greater than 22.9% as Br2 (10.2% as C12).

  Liquid and solid bromine-containing compositions are described. A liquid mixed halogen composition is also described. The highly concentrated liquid compositions and the high-activity solid compositions have excellent physical and chemical stability. The compositions are effective biocides in water treatment. Methods of preparing the compositions are also disclosed. These include combining a bromine compound in the oxidation state of -1 with hydrogen peroxide and a complexing agent followed by the addition of an alkaline source. The methods may further include the use of a solid organic or solid inorganic halogenating agent, conducting a solid-liquid separation, and adding an alkaline source.

  The present invention is directed to convenient methods of preparing: (1) highly concentrated liquid bromine-containing biocidal solutions and (2) highly concentrated mixed halogen liquid bromine and chlorine-containing biocidal solutions that have excellent physical and chemical stability. One method involves adding the acidic reaction medium to an alkaline source to effect the final pH adjustment and in another these are co-fed into a common reaction vessel. Both methods minimize the incidence of the acid hydrolysis reaction that undermines chemical yields and generates troublesome sulfate by-products. The methods offer superior reactor cooling efficiencies that reduce batch cycle times and suppress undesirable elevated temperature decomposition reactions.

  本发明涉及便利的制备方法：(1) 高浓度液体溴含生物杀菌溶液和 (2) 具有优异物理和化学稳定性的高浓度混合卤素液体溴和氯含生物杀菌溶液。一种方法涉及将酸性反应介质添加到碱性源中以实现最终pH调整，在另一种方法中，它们共同进入一个反应容器。这两种方法都最大程度地减少了破坏化学产率并生成麻烦的硫酸盐副产物的酸水解反应的发生。这些方法提供了优越的反应器冷却效率，可以减少批处理周期时间并抑制不良的高温分解反应。
