4、CAS:Anhydrous:127-09-3,Trihydrate:6131-90-4

5、Character:Trihydrate:It iscolorless transparent crystal orwhite crystalline powder.Relative density is1.45.In warm and dry air, it’ll easily get weathered. 1g sample could be dissolved in about 0.8mL water or 19mL ethanol. Anhydrous: It is white crystalline coarse powder or block. It’sodorless,tastes a bit ofvinegary.Relative density is 1.528. Melting point is 324℃.Capacity ofmoisture absorptionis strong.1g sample could be dissolved in 2mL water.

6、Usage:It is used as buffering agent, seasoning reagent,pH regulator, flavor agent, etc.

7、Packing:It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

8、Storage and Transport:It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.

1、测定铅、锌、铝、铁、钴、锑、镍和锡。络合稳定剂。乙酰化作用的辅助剂、缓冲剂、干燥剂、媒染剂。

2、用于测定铅、锌、铝、铁、钴、锑、镍、锡。用作有机合成的酯化剂以及摄影药品、医药、印染媒染剂、缓冲剂、化学试剂、肉类防腐、颜料、鞣革等许多方面。

3、用作缓冲剂、调味剂、增香剂及ph值调节剂。作为调味剂的缓冲剂,可缓和不良气味并防止变色改善风味时使用0.1%~0.3%。具有一定的防霉作用,如使用0.1%~0.3%于鱼肉糜制品及面包。亦可用作调味酱、酸菜、蛋黄酱、鱼糕、香肠、面包、黏糕等的酸味剂。与甲基纤维素、磷酸盐等混合,用于提高香肠、面包、黏糕等的保存性。

4、用作硫黄调节型氯丁橡胶炼焦的防焦剂,用量一般为0.5质量份。还可用作动物胶的交联剂。

5、本品可用于碱性电镀锡的添加,但对镀层及电镀过程并无明显影响,不是必要成分。乙酸钠常用作缓冲剂,如用于酸性镀锌、碱性镀锡和化学镀镍。
