The addition of Acid corrosion Inhibitor RXSOL 213, inhibitors to hydrochloric acid solution provides maximum protection for equipment during:

• a. The removal of lime deposits or water scale from power plant boilers and piping systems and from evaporating equipment.
• b. The removal of scale and deposits from equipment in refineries, utility companies,paper mills, chemical plants and other industries.

Acid corrosion Inhibitor RXSOL 213 inhibitors meet the requirements of Military Specification Nos.MIL-I-17433 and MIL-C-17434.

For each 1000 gallons of either 5% or 10% by weight* hydrochloric acid solution, not less than the following amount of Acid corrosion Inhibitor RXSOL 213 or RODINE 214 inhibitor should be used:

1 Gallon for a cleaning temperature of 150° Fahrenheit.
2 Gallons for a cleaning temperature of 175° Fahrenheit.
3 Gallons for a cleaning temperature of 200° Fahrenheit.

* A 5% by weight hydrochloric acid solution contains 14.1% by volume of 20° Be hydrochloric acid.

The exceptional strength and heat stability of Acid corrosion Inhibitor RXSOL 213 give the user a considerable safety factor in relation to temperature, acid strength, and time. Acid corrosion Inhibitor RXSOL 213 may be added to either the diluted or concentrated hydrochloric acid. In either case, Acid corrosion Inhibitor RXSOL 213 should be thoroughly mixed with the acid by stirring or agitation.

The hydrochloric acid solution inhibited with Acid corrosion Inhibitor RXSOL 213 is best circulated through the equipment to be cleaned. When circulation cannot be accomplished, the equipment should be filled with the inhibited acid and allowed to react for sufficient time to remove the objectionable deposits. To estimate the proper acid concentration and cleaning time, samples of the deposits to be removed can be tested in the laboratory prior to cleaning. If heating of the equipment to be cleaned or acid solution is desired to speed the cleaning action, it should be done prior to the start of the cleaning operation

ACID inhibitor for HCl, Hydrochloric Acid. 

Acid corrosion Inhibitor RXSOL 213 also resulting good corrosion and antiscaling effect. 

It's good resistance towards High and Low pH value makes it unique and better than that of other organophosphoric acids (salt). Acid corrosion Inhibitor RXSOL 213 also resulting high chlorine oxidation tolerance properties.

Acid corrosion Inhibitor RXSOL 213 has good antiscale and visible threshold effects.
