MONO-AND DI-SUBSTITUTED(DIPHOSPHONOALKYLAMINO METHYL)-4- HYDROXYBENZENESULFONIC ACID

摘要

New polyamino-polyphosphonic-hydroxybenzenesulfonic acid compounds as the free acid or their alkali or alkaline earth metal salt. Specifically, the compounds are the mono- and di-(1,1-diphosphono-1-alkylaminomethyl)-4-hydroxybenzenesulfonic acid. These compounds are useful as corrosion inhibiting agents for metal/water applications.
