I. Chemical name: citric acid
2. Alias: 3-hydroxy-1,3,5-pentanoic acid or 2-hydroxypropane-1,2,3-tricarboxylic acid
III. CAS: 77-92-9
IV. chemical formula: C6H8O7
V. appearance and performance: white crystalline powder
Vi. application: the corrosion inhibition of citric acid in detergents is also prominent. As an important part of chemical cleaning, acid pickling is relatively weak compared with inorganic acid, so the corrosivity of equipment is relatively small, the safety and reliability of citric acid cleaning is relatively strong, and the waste liquid is relatively easy to handle, which is not good for human body Can cause harm
