- 概述:酒石酸钾钠(分子式KNaC4H4O6·4H2O)也称酒石酸钠钾、罗氏盐、罗谢尔盐,是酒石酸钠与酒石酸钾形成的复盐。它是无色至蓝白色正交晶系晶体,可溶于水,微溶于醇,味咸而凉,水溶液呈微碱性。比重1.79,PH值为6.8-8,熔点70-80°C,在热空气中稍有风化性。60°C开始失去部分结晶水,100°C时失去3个水分子,215°C时失去全部结晶水变成无水盐,酒石酸钾钠分D型和DL型两种,D型为无色透明结晶体,在水中的溶解度30℃时100 ml为138.3g。不溶于醇。具有络合性,能与铜、铁、铅、铬、锦等金属离子在碱性溶液中形成可溶性络合物。DL型为白色细粒结晶体,密度1.783g/cm3。熔点100℃。在热空气中有风化性,60℃失去部分结晶水,215℃失去全部结晶水。在水中的溶解度30℃时l00ml为117.62g不溶于醇。具有络合性。 两摩尔的酒石酸氢钾溶于水加热,加入一摩尔碳酸钠,趁热过滤,不溶物干燥结晶,即得到酒石酸钾钠。 可用作缓泻剂、食品添加剂、压电元件,也可作化学试剂,用于配制菲林试剂、双缩脲试剂以及作为制镜时的还原剂。
- 用途一:用于费林溶液、斑氏溶液的配制,还用作压电元件
- 酒石酸钾钠的作用与用途:用于配制斐林氏溶液、双缩脲试剂,掩蔽剂、还原剂测定,食品添加剂,血清蛋白的生化检验。还用于印刷工业制版、制镜;热水瓶工业作还原剂;电镀工业作络合剂;医药上作缓泻剂;电讯工业上用以制晶体喇叭及话筒;化肥工业ADA脱硫剂等。
- 制备方法与生产工艺:将原料酒石酸放入缸内,加入二倍量的水,用蒸汽加热煮沸后,在不断搅拌下,慢慢加入干态的碳酸钠中和,直至不产生气泡为止。这时溶液用石蕊试纸试验呈中性。趁热用布袋过滤。滤液应透明或接近透明。将滤液移入搪瓷桶内,加热蒸发浓至溶液浓度为38-42波美度,取出置于浅盘内(厚度以15-20厘米为宜),在室温下静置24小时即自然结晶。分出母液,取出结晶,用冷水洗涤一次(洗水与母液合并回收),即得酒石酸钾钠粗制品。将粗制品加适量水(1-2倍)加热溶解,加入活性炭脱色(活性炭加入量为样品量的5-15%)搅拌10分钟后,过滤(滤液用粗结晶的处理办法,进行再
