Hardcover Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.

- 硫化碱:硫化钠又称硫化碱、臭苏打、臭碱,常温下纯品为无色或微紫色的棱柱形晶体,工业硫化钠因含杂质常为粉红、棕红色、土黄色块。有腐蛋臭味,有腐蚀性,有毒,密度2.427。在920℃分解。能溶于冷水,易溶于热水,溶于水时几乎全部水解为氢氧化钠和硫氢化钠(10℃时溶解度为15.4g,90℃时溶解度为57.2g),水溶液呈强碱性,对铜、木材、皮肤等都有腐蚀性。微溶于乙醇,不溶于乙醚。硫化钠遇强酸起反应放出硫化氢。在空气中潮解,易氧化生成硫代酸钠。硫化钠主要用作生皮脱毛剂,纸浆蒸煮剂,硫化染料的原料,染料中间体还原剂,织物染色媒染剂,矿石浮选剂,也可用作粘胶纤维脱硫剂以及生产硫氢化钠和多硫化钠原料等。 我国硫化钠起源于19世纪30年代,最早由辽宁大连一家化工厂开始小规模的生产,进入80年代至90年代中期,随着国际化工工业的蓬勃发展,国内硫化钠产业发生了根本性转变,生产厂家和规模剧增,发展迅猛。由山西运城为中心的硫化钠生产区域快

- 储运特性:库房通风低温干燥; 与氧化剂、酸类分开存放。
- 灭火剂:水、砂土
- 用途二:染料工业中用于生产硫化染料,是硫化青和硫化蓝的原料。印染工业用作溶解硫化染料的助染剂。制革工业中用于水解使生皮脱毛,还用以配制多硫化钠以加速干皮浸水助软。造纸工业用作纸张的蒸煮剂。纺织工业用于人造纤维脱硝和硝化物的还原,以及棉织物染色的媒染剂。制药
- 毒性分级:高毒
- 防护措施:硫化钠对皮肤有强腐蚀性,接触硫化钠溶液的工人手部皮肤发生皱裂,发红。操作时应加注意。误触皮肤,可用水冲洗。硫化钠飞沫或小块落入眼内立即用水冲洗15min后,送医院治疗。为了保护皮肤,建议经常用弱乙酸溶液擦手,然后涂以油质性软膏。注意保护眼睛。

- 类别:腐蚀物品
- HazardClass:4.2
- 参考质量标准二:参见硫化钠企业标准新0014-89
- 方法二:精制法以生产沉淀硫酸钡过程中副产的浓度为4%左右的硫化钠溶液为原料,用泵打人双效蒸发器蒸浓至23%后,进人搅拌罐脱铁、除碳处理后,用泵打人蒸发器(用纯镍材制造)蒸发碱液达到浓度,送到滚筒水内冷却式制片机制成后,经筛选、包装而得成品。 煤粉还原芒硝法该法是硫化钠传统的生产方法,在加工过程中改进设备、材质、增加除铁工序使产品达到标准。
