1·This article described the crystal model of anhydrous sodium sulfate in DTB crystallizer.

论述了用dtb型结晶器结晶硫酸钠结晶模型。

2·After reaction, the purified product was obtained through extraction with dichloromethane, drying with anhydrous sodium sulfate and desolventizing.

反应后用二氯甲烷萃取，无水硫酸钠干燥，除去溶剂后得到纯净产物。

3·Compared with previous years, there is a substantial increase on the domestic output of anhydrous sodium sulfate and the entire distribution of the production has also changed a lot.

与前几年相比，中国元明粉产量有了大幅度增长，整体布局也发生了巨大变化。

4·Textile industry, anhydrous sodium sulfate used in cement, chemical fertilizer, shipbuilding, petroleum and other departments, the cotton textile industry is the largest industrial sector.

工业有纺织、无水硫酸钠用于水泥、化肥、造船、石油开采等部门，棉纺织业是最大的工业部门。

5·And the results were anhydrous sodium sulfite 0.2%, sodium lauryl sulfate 7%, fatty alcohol polyoxyethylene lauryl ether sulfate sodium 12% and dodecyl betaine 4%.

优选结果为0.2%无水亚硫酸钠、7%十二烷基硫酸钠、12%脂肪醇聚氧乙烯醚硫酸钠和4%十二烷基甜菜碱。
