Beschreibung
1,3-Dibromo-5,5-dimethylhydantoin is an important chemical product and has been widely applied in chemical, pharmaceutical and agricultural industries with various kinds of advantages including excellent stability, high content of bromine and high reactive activity.
Chemische Eigenschaften
solid
Verwenden
Brominating agent. Analytical reagent for determination of iodide and organic iodine, and for identification tests.
Application
Many domestic and foreign experts believe that the most significant oxidizing biocide is the compound halogenated compound formulation combining BCDMH and 1,3-Dibromo-5,5-dimethylhydantoin(DBDMH). In agriculture, DBDMH is mainly used for aquaculture including pond disinfection, prevention of water disinfection, disease treatment, etc., and is not affected by water quality, salinity, pH, temperature, and other organic compounds during usage. In addition, there has been already cases in which people has applied DBDMH as high-efficiency and low-toxicity disinfectant for combined formulation with stearic acid monoglyceride and Tween-80 and applied to the surface of the orange for preventing mold and preservation, and has already achieved excellent results.
Allgemeine Beschreibung
Currently, the combined formulation between 1,3-Dibromo-5,5-dimethylhydantoin(DBDMH) and other halogenated hydantoin for application has become a hotspot in recent years such as the combined application of BCDMH and DBDMH as well as the combined application of DCDMH and DBDMH. For the combined formulation of DBDMH and other halogenated hydantoin, one critical factor is the ratio between effective chlorine and effective bromine.
l?uterung methode
Recrystallise it from H2O. Its solubility in CCl4 is 0.003 mol/L at 25o and 0.024 mol/L at 76.5o. [Beilstein 24 III/IV 1101.]
