Sodium Bromide Molecular weight: 102.89 CAS No.: 7647-15-6 EC No.: 231-599-9 ISO9001:2000 Sodium Bromide is a single salt (NaBr). It has the following feature and benefits: - It is non-damaging to the formation, - It is thermally and chemically stable, - It can be blended with other solutions of bromides and chlorides, and - It is especially useful when used in formations that are known to have calcium sensitivity. It can be used with Sodium Chloride brine to formulate non-damaging fluids of densities from 10.0ppg to 12.7ppg. It can also be usedaswater treatment in pool spa, nerve ataractic in medicine, sensitive emulsions in photograph etc. Sodium Bromide Specification Industrial GradeMedicine GradeSensitive GradeAppearance White crystalWhite crystalWhite crystalPurity, % 98.5 min99.0 min99.5 minMoisture, % 1.0 max1.0 max0.5 maxChloride (Cl), % 1.0 max0.3 max0.25 maxBromate (BrO3), % --0.003 maxIodide (I), % --0.005 maxSulphate (SO4), % 0.05 max0.02 max0.01 maxpH (5% solution) 6.0-8.06.0-8.06.0-8.0Arsenic (As), mg/kg -10 max0.2 maxLead (Pb), mg/kg -10 max0.2 maxMercury (Hg), mg/kg --0.3 maxMicroelement, mg/kg --0.5 maxUse: offshore oil, marine oil, oil drilling, sensitive photographic film, medicine, dye etc. Packing: PP woven bag with PE liner or fibre drum.
