请问有谁知道Na[Al(OH)4]是什么?这个东西能做什么用?
Na[Al(OH)4]其实就是偏铝酸钠和两个H2O .给出两个化学方程式：CO2(过量)+Na[Al(OH)4]=NaHCO3+AL(OH)3 CO2(少量)+2Na[Al(OH)4]=Na2CO3+2AL(OH)3+H2O偏铝酸钠,化学式NaAlO2,白色、无臭、无味,熔点1650℃,呈强碱性的固体,高温熔融产物为白色粉末,溶于水,不溶于乙醇,在空气中易吸收水份和二氧化碳,水中溶解后易析出氢氧化铝沉淀,氢氧化铝溶于氢氧化钠溶液也生成偏铝酸钠溶液.用作纺织品的媒染剂、纸的填料、水的净化剂等.可用氧化铝与固态氢氧化钠或碳酸钠共熔制得.偏铝酸钠遇弱酸和少量的强酸生成白色的氢氧化铝沉淀,现象是有大量的白色沉淀生成,且最终沉淀的量不变.而遇到过量的强酸生成对应的铝盐,现象是先有白色沉淀生成,过一段时间后,白色沉淀的质量逐渐减小,最后消失.偏铝酸钠和碱不作用.因为它本身由于偏铝酸根离子水解,使得溶液显碱性,所以,它是不和碱作用的.主要用途：1.土木工程方面,本品与水玻璃混合用于施工中的堵漏.2.造纸行业,本品与硫酸铝混合使用是一种良好的填充剂.3.水处理方面,可做净水剂助剂.4.可做为水泥速凝剂.5.在石油化工、制药、橡胶、印染、纺织、催化剂生产中也有较广泛的应用.6.钛白粉生产过程中使用该产品,使其表面包膜,提高其特性.
