Scale formation inhibiting process using silicon-containing aminomethyl phosphonates

Abstract

Abstract SILICON-CONTAINING AMINOMETHYL, OR SUBSTITUTED AMINOMETHYL, PHOSPHONIC ACIDS AND DERIVATIVES THEREOF. THE SILICON ATOM IS SILICONE FUNCTIONAL (I.E. HAS A -SIOGROUP) AND IS ALSO ATTACHED TO AN ALKYLENEAMINO GROUP WHICH MAY HAVE ONE OR MORE AMINO GROUPS (I.E. AN ALKYLENEAMINO GROUP HAVING AT LEAST ONE N-H GROUP) CAPABLE OF REACTING WITH A CARBONYL COMPOUND (I.E. ALDEHYDE OR KETONE) AND PHOSPHOROUS ACID, OR A DERIVATIVE THEREOF, TO FORM AMINOMETHYL PHOSPHONIC ACID. ALL, OR LESS THAN ALL, OF THE N-H GROUPS MAY BE CONVERTED TO AMINOMETHYL PHOSPHONIC ACIDS. THE SILICON-AMINOMETHYL PHOSPHONIC ACIDS MAY BE MONOMERIC, POLYMERIC, OR COPOLYMERIC. THEY ARE USEFUL, FOR EXAMPLE AS CORROSION INHIBITORS, SCALE INHIBITORS, WATER CLARIFIERS AND FOR OTHER USES.
