  • Corrosion inhibitor for highly oxygenated systems
    Patent number: 4311662
    Abstract: This invention relates to the use of phosphorylated oxyalkylated polyols as corrosion inhibitors in highly oxygenated systems such as experienced in air drilling. These corrosion inhibitors not only inhibit general or overall corrosion but also inhibit localized corrosion of the pitting type.
    Type: Grant
    Filed: February 13, 1978
    Date of Patent: January 19, 1982
    Assignee: Petrolite Corporation
    Inventor: Thomas J. Bellos
  • Ureylenes and uses thereof
    Patent number: 4303780
    Abstract: This invention relates to ureylene prepared by reacting an oxyalkylated polyamine with urea and to uses of such ureylene for example in removing oils, solids, and combinations thereof from aqueous systems, etc.
    Type: Grant
    Filed: February 26, 1980
    Date of Patent: December 1, 1981
    Assignee: Petrolite Corporation
    Inventor: Thomas J. Bellos
  • Use of phosphorylated oxyalkylated polyols in conjunction with sulfite and bisulfite oxygen scavengers
    Patent number: 4213934
    Abstract: This invention relates to the use of phosphorylated oxyalkylated polyols (POP) in conjunction with sulfite oxygen scavengers in inhibiting corrosion in oxygen-containing systems. The phosphorylated oxyalkylated polyols are effective in inhibiting the precipitation of the sulfite and bisulfite oxygen scavengers as scale.
