    摘要： Alkyl phosphonates prepared from amino acids suitable for use in inhibiting scale. The phosphonates are obtained as reaction mixtures where the level of alkyl phosphonation is deliberately controlled to provide only partial alkyl phosphonation of the amino acid. The resulting alkyl phosphonates exhibit improved environmental properties compared to the fully substituted species, while still exhibiting acceptable efficacy in the control of scale. The compositions possess advantages over existing phosphonates in that they exhibit higher biodegradation by method OECD 306. They also offer lower toxicity to marine life compared to the fully substituted species and are not expected to bioaccumulate.
