&amp;#039;&amp;#039;&amp;#039;Axit maleic &amp;#039;&amp;#039;&amp;#039;là một hợp chất hữu cơ 2 gốc carboxyl có công thức phân tử HO&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;CCHCHCO&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;H. Axit maleic là dạng [[Đồng phân cis-trans|đồng phân cís]] của axit but-2-endioic. Axit maleic có các phản ứng với base, oxit base, kim loại và muối. Nó cũng có phản ứng cộng và phản ứng este hoá. Khác với [[axit fumaric]], nó có phản ứng tách nước tạo anhydride.&lt;br /&gt;
