硫化堿
硫化堿
    硫化鈉,無機化合物,又稱臭堿、臭蘇打、黃堿、硫化堿。純硫化鈉為無色結晶粉末。吸潮性強,易溶于水。水溶液呈強堿性反應。觸及皮膚和毛發時會造成灼傷。故硫化鈉俗稱硫化堿。硫化鈉水溶液在空氣中會緩慢地氧化成硫代硫酸鈉、亞硫酸鈉、硫酸鈉和多硫化鈉。由于硫代硫酸鈉的生成速度較快,所以氧化的主要產物是硫代硫酸鈉。硫化鈉在空氣中潮解,并碳酸化而變質,不斷釋出硫化氫氣體。工業硫化鈉因含有雜質其色澤呈粉紅色、棕紅色、土黃色。比重、熔點、沸點,也因雜質影響而異。
用途:
    1.染料工業中用于生產硫化染料,是硫化氫和硫化藍的原料;
    2.印染工業用作溶解硫化染料的助染劑;
    3.制革工業中用于水解使生皮脫毛,還用以配制多硫化鈉以加速干皮浸水助軟。造紙工業用作紙張的蒸煮劑;
    4.紡織工業用于人造纖維脫硝和硝化物的還原,以及棉織物染色的媒染劑;
    5.制藥工業用于生產非那西丁等解熱藥。此外還用于制硫代硫酸鈉、硫氫化鈉、多硫化鈉等。
