1171 工业用合成盐酸
HCL

产品简介:
  
氯气和氢气反应合成氯化氢的水溶液,由于在工业生产中夹有铁等微量杂质,故呈现为淡黄色。它具有刺激性臭味,是一种可挥发性强酸,有毒,有腐蚀性,容易和许多金属反应,可与碱金属和碱土金属反应,也可与许多金属氧化物以及多种金属盐起反应。在冶金、纺织、皮革、医药等行业都有广泛的应用。

Refined Hydrochloric acid

Introduction of product:
  
HCL solution formed by Cl 2 and H 2 is light yellow due to a small quantity of impurities such as Fe in industrial production. It is of strong acidity with irritant odour, volatile, poisonous and erosive, prone to react with many metals, including alkali metals and alkali earth metals, many metallic oxide and metallic salts. It is very popular with many fields, such as metallurgy, textile, leather and pharmacy industry.
