ABSTRACT:
N,N-bis(phosphonomethyl)-2-amino-1-propanol, derivatives and corresponding lower alkyl ethers and N-oxides thereof possess high calcium tolerance and have been found to give excellent inhibition of the formation, deposition and adherence of scale-forming salts, especially calcium carbonate, under severe conditions which include elevated pH, high dissolved solids content, and high saturation levels of calcium carbonate.
