dvr Acid corrosion Inhibitor RXSOL 213

Inhibitor for ACID

Acid corrosion Inhibitor RXSOL 213  is an organic, liquid, cationic corrosion inhibitor especially designed to inhibit the attack of hydrochloric acid oiron and steel during industrial cleaning operations. It also inhibits acid attack on copper and brass. It does not contain arsenic, chlorinated hydrocarbons, or lead compounds.


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.

Using Procedure:

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° Bé 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


Storage and Disposal

Acid corrosion Inhibitor RXSOL 213 and will not freeze at temperature as low as -20° Fahrenheit. Below 0° Fahrenheit,Acid corrosion Inhibitor RXSOL 213 become very viscous and may be difficult to pump. It is recommended that Acid corrosion Inhibitor RXSOL 213  be stored in a dry area where the temperature will not go lower than 0° Fahrenheit.

Applicable regulations concerning disposal and discharge of chemicals should be consulted and followed-

Disposal information for Acid corrosion Inhibitor RXSOL 213 is given on the Material Safety Data Sheet for each product.The industrial cleaning bath is acidic and contains hydrochloric acid and organic Acid corrosion Inhibitor RXSOL 213  components. Waste treatment , neutralization is required. The industrial cleaning bath and sludge can contain ingredients other than those in the chemical as supplied and analysis of the solution and/or sludge is required before waste treatment and disposal.

Safety and Handling :

Before handling the chemical products used in this process, the first aid and handling recommendations on the Material Safety Data Sheet for should be read, understood and followed. The industrial cleaning bath is strongly acid and can burn skin and eyes. Refer to the Material Safety Data Sheet for hydrochloric acid for recommendations for protective action.
