Acid Cleaner with Corrosion Inhibitor

Phosphoric acid (85% sol n.) Gluconic acid (50% sol n.) Trisodium phosphate Water 

With continuous agitation, add the trisodium phosphate to the water. When dissolution is complete, slowly add the gluconic and phosphoric acids. Add Amphoterge KJ-2 and Unihib 305-LC and continue agitation to a clear, uniform status.

Alkyl phosphates, also coco based, are formed by the reaction of fatty alcohol with phosphorous pentoxide. The product is a mixture of monoesters and diesters. Its sodium salt (MAP) is reportedly mild and is used in facial wash, such as Kao s Biore. Other uses are as antistatics in textile auxiliaries, corrosion inhibitors, surfactant additives for extreme pressure (EP) lubricants, and surfactant components in alkali and acid cleaners. Coco-based alkyl polyglycosides (APG) have been successfully produced and marketed by Henkel in the United States. The alkyl polyglycoside fuUy satisfies the demand for a mild surfactant and is completely biodegradable.

Mixtures of EDTA with hydrazine (frequently also containing citric acid) received extensive evaluation as solvents for deposits found in nuclear steam generators. Pitzer made the first solvents containing EDTA and hydrazine but did not conduct corrosion tests. Pocock and Leedy tested a number of potential steam-generator cleaners at 149°F and 203°F (65°C and 95°C). An EDTA/citric acid hydrazine mixture was compared with thioglycolic acid, hydroxyacetic/formic, citric/formic, and citric/formic-hydrazine. All of the solvents were inhibited with commercial inhibitors. The EDTA...
