  • 人關注

化 學 名:

檸檬酸

英文名稱:

Citric acid

分 子 式:

C6H8O7

分 子 量:

192.122

CAS NO

77-92-9

性  能:

相對密度1.542,熔點153(失水),折射率 1.493~1.509 
無色半透明的結晶或白色的顆粒,或白色結晶狀粉末,常含一分子結晶水,無臭,味極酸,溶于水、醇和乙醚。其鈣鹽在冷水中比熱水中易溶解,此性質常用來鑒定和分離檸檬酸。結晶時控制適宜的溫度可獲得無水檸檬酸。水溶液呈酸性。在干燥空氣中微有風化性,在潮濕空氣中有潮解性。175℃以上分解放出水及二氧化碳。 

用  途:

用作清洗、水處理、印染行業等。

包  裝:

內襯聚乙烯塑料袋,外套塑料編織袋,每袋25Kg。

貯存與運輸:

應貯在干燥、通風清潔的庫房中。
