How to buy hydrochloric acid?
Thread Content
Where can I buy hydrochloric acid? For small-scale use, 1 to 2 tons of concentrated hydrochloric acid per year is sufficient
Ask the university research lab; a certificate from the local public security bureau is required.
I remember that registration is required~~~~ Some pharmaceutical companies also use hydrochloric acid in their recycled resins, and such uses require registration~~~
A few tons per year is truly too small a quantity; there is an excess supply of hydrochloric acid, and it becomes difficult to maintain balance of chlorine elements in the production of chlor-alkali products.
