简介:Maleic and fumaric acid can be reduced electrochemically to succinic acid. In acidic
solutions a differentiation of the two acids is not possible since both are reduced at
the same potential. On the other hand, separat简介:Maleic and fumaric acid can be reduced electrochemically to succinic acid. In acidic
solutions a differentiation of the two acids is not possible since both are reduced at
the same potential. On the other hand, separation at pH 7.8 ... 8.0 is easily possible
since fumaric acid is now more difficult to reduce at the lower proton concentration
(as a result of cis-trans isomerism) than maleic acid.详细>
