Hydrogen bromide is the inorganic compound with the formula HBr. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature.

溴化氢，是一种无机化合物，化学式为HBr，与水混溶，可混溶于乙醇、乙酸，标准情况下为无色气体，主要用于制造各种溴化合物，也可用于医药、染料、香料等工业。

氢溴酸是溴化氢的水溶液，其pKa为−9，酸性比盐酸强，但比氢碘酸弱。 它是最强的无机酸之一。 氢溴酸主要被用于生产无机溴化物，清除醇盐和酚盐，取代反应中取代羟基，以及与烯烃加成。 它也可以催化矿物提取和某些烷基化反应。 有机化工工业在生产有机溴化物的同时副产大量的氢溴酸废液，一方面该废液成分复杂，不易处理；另一方面直接排放对环境污染严重。 其中一部分用于制备溴十二烷，但效果并不理想，溴十二烷常用的制备方法有：溴化氢气体法、赤磷溴化法、浓 …
