Thiocarboxylic Acid Anhydrides (i.e., Compounds Having The -c(=x)-x C(=x)- Group, Wherein The X's May Be The Same Or Diverse Chalcogens And At Least One X Is Sulfur) Patents (Class 562/886)
  • Publication number: 20040103820
    Abstract: A 2-methoxyphenol derivative and an ink composition containing the 2-methoxyphenol derivative, an aqueous medium, and a colorant enhance light resistance by absorbing ultraviolet (UV) light, provide wettability and stabilize a colorant. The ink composition prepared using the 2-methoxyphenol derivative also has improved light resistance, wettability and stabilizes a colorant and does not require an additional light-resistant agent.

  • Patent number: 6469206
    Abstract: Disclosed is a process for the preparation of trifluoromethanesulfonic acid anhydride by the steps of (1) forming a mixed anhydride comprising a trifluoromethanesulfonyl acyl residue and a carboxyl residue by contacting trifluoromethanesulfonic acid or a derivative thereof with a carboxyl compound selected from ketene, dialkyl ketenes, carboxylic acids, and derivatives of carboxylic acids and (2) subjecting the mixed anhydride to reactive distillation wherein the mixed anhydride undergoes disproportionation to produce triflic anhydride and a higher boiling carboxylic acid anhydride.
