  • Process for making dihydrocarbyl hydrocarbonphosphonates
    Patent number: 8344171
    Abstract: This invention provides a process for the preparation of a dihydrocarbyl hydrocarbonphosphonate. The process comprises forming a reaction mixture from components comprising (i) at least one dihydrocarbyl phosphite, (ii) at least one alkali metal hydrocarbyloxide, and (iii) at least one alcohol, so that a dihydrocarbyl hydrocarbonphosphonate is formed.
    Type: Grant

  • OLIGOMERIC PHOSPHONATE COMPOSITIONS, THEIR PREPARATION AND USES
    Publication number: 20100063311
    Abstract: This invention provides oligomeric hydrogen phosphonates represented by the formula (I) where R is an alkyl group having one to about six carbon atoms; R? is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group having two to about twenty carbon atoms or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring, where at least one of R? is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group and at least one of R? is a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; and n is a number from 2 to about 20. Also provided are processes for making these oligomeric hydrogen phosphonates, oligomeric organophosphonate compositions, and processes for making these oligomeric organophosphonate compositions.
