    摘要： Formylating the amino nitrogen of an alkali metal salt of an amino carboxylic acid, by reacting the salt with an alkyl formate in an alkanol solvent. In one embodiment, the alkyl formate is added to the reaction as such; in another embodiment, the alkyl formate is formed in situ by reaction of carbon monoxide with the alkanol solvent in the presence of the alkali metal salt of the amino carboxylic acid. The process provides a new class of compounds, the alkali metal salts of N-formyl-aspartic acids.

    摘要： Polyether bis-phosphonic acid compounds are disclosed which have the formula (HO).sub.2 OP--R--(OR').sub.n --OR--PO(OH).sub.2 where R is selected from the group consisting of methylene and ethylene, R' is selected from the group consisting of ethylene and ethylene substituted with one or more methyl groups, and n is an integer from 1 to 4, water soluble salts thereof, and esters thereof with alkyl groups having from 1 to 6 carbon atoms. Also disclosed is a novel preparation of these compounds by reacting hydroxyalkylphosphonic acid dialkyl ester compounds with 2-benzyloxyalkyl organic sulfonates; reacting the intermediate formed therefrom with hydrogen or a hydrogen source; reacting the intermediate formed therefrom with a hydrogen ion acceptor and certain sulfonyl chlorides; and reacting the intermediate formed therefrom with hydroxyalkylphosphonic acid dialkyl ester compounds to form a polyether bis-phosphonic acid compound which may be hydrolyzed to form the polyether bis-phosphonic acid.
