性狀
無色立方晶體。無臭，味咸而微苦。相對密度2.75。熔點734℃，沸點1435℃。見光易變黃，稍有吸濕性。溶于水(100℃時溶解度為102g／100 ml水)和甘油，微溶于乙醇和乙醚。水溶液呈中性。其溴離子可被氟、氯取代。與硫酸反應可生成溴化氫。與硝酸銀反應生成黃色溴化銀沉淀。
所屬類別
無機化工產(chǎn)品: 無機鹽: Cc溴化合物
用途與作用
感光材料工業(yè)用于制造感光膠片、顯影藥、底片加厚劑、調色劑和彩色照片漂白劑等。醫(yī)藥上用作神經(jīng)鎮(zhèn)靜劑(三溴片)。此外還用于化學分析試劑，分光和紅外線的傳遞，制特種肥皂，以及雕刻、石印等方面。
合成工藝與制法
尿素還原法將溶有尿素的苛性鉀溶液送人反應器中，于80℃緩慢加入溴素進行反應，至Ph值為6--7時反應完全。將反應液加入貯槽用活性炭脫色，待溶液澄明后再過濾、蒸發(fā)、結晶、離心分離、干燥，即得溴化鉀成品。其反應式如下：
3Br2+6KOH+CO(NH2)2→6KBr+5H2O+CO2↑+N2↑
