瑞典一家公司推出了一种制取三硫化铝的新工艺．方法是：首先将sc·rg硫化钠加入用酸钠水溶液中（2·gg三氧化用溶于1．6g奇性钠中），获得硫化钠酸钠，冷至15C，加60mL95％的乙霞，搅拌加55mL43％的硫酸，温度保持在15C以上，形成沉淀，进行过治、洗涤，直至不含硫酸盐离子． A Swedish company has introduced a new process for making aluminum trisulfide. The method is as follows: First, add sc · rg sodium sulfide to sodium acid aqueous solution (2 gg trioxide dissolved in 1.6g singular sodium) to obtain sodium sodium sulfite, cool to 15C, add 60mL95% Baxia , Stirring 55mL43% sulfuric acid, the temperature was maintained at 15C above, the formation of precipitation, over treatment, washing until sulfate-free.
