  • Use of novel ethers as oxydimethylating agents
    Patent number: 4100200
    Abstract: A compound having the formulaR -- SO.sub.2 O -- CH.sub.2 -- O -- CH.sub.2 -- OSO.sub.2 -- Rwherein R is alkyl, is prepared by reacting a compound having the formula ##STR1## wherein R and R' are alkyl with a cyclic polyoxymethylene or a linear polyoxymethylene in a substantially humidity-free environment. The compound is useful as an oxydimethylating agent for organic compounds.
    Type: Grant
    Filed: February 11, 1977
    Date of Patent: July 11, 1978
    Assignee: Eastman Kodak Company
