性状
无色立方晶体。无臭，味咸而微苦。相对密度2.75。熔点734℃，沸点1435℃。见光易变黄，稍有吸湿性。溶于水(100℃时溶解度为102g／100 ml水)和甘油，微溶于乙醇和乙醚。水溶液呈中性。其溴离子可被氟、氯取代。与硫酸反应可生成溴化氢。与硝酸银反应生成黄色溴化银沉淀。
所属类别
无机化工产品: 无机盐: Cc溴化合物
用途与作用
感光材料工业用于制造感光胶片、显影药、底片加厚剂、调色剂和彩色照片漂白剂等。医药上用作神经镇静剂(三溴片)。此外还用于化学分析试剂，分光和红外线的传递，制特种肥皂，以及雕刻、石印等方面。
合成工艺与制法
尿素还原法将溶有尿素的苛性钾溶液送人反应器中，于80℃缓慢加入溴素进行反应，至Ph值为6--7时反应完全。将反应液加入贮槽用活性炭脱色，待溶液澄明后再过滤、蒸发、结晶、离心分离、干燥，即得溴化钾成品。其反应式如下：
3Br2+6KOH+CO(NH2)2→6KBr+5H2O+CO2↑+N2↑
