公开号:US04156686A1
公开(公告)日:1979-05-29
A process for preparing alkyl maleic anhydrides which comprises heating a lower alkenyl succinic anhydride in the presence of a catalytic amount of ruthenium or a catalytic salt thereof under conditions effective to isomerize the alkenyl succinic anhydride.
Polymer thickeners having a viscosity of at least 10 K, employed in acid media are stabilized with Redox indicators having from 6 to 30 carbon atoms, such as, for example, methylene blue, phenosafranine, pyronine Y, tartrazine, amaranth, methyl orange, and alkali metals salt of diphenylamine sulfonate and malachite green oxalate, which stabilizers are combined with the polymer in a concentration of between about 0.005 to about 1 weight %.
