The present invention relates to dichloromaleic acid diamides of the formula ##STR1## in which R represents an optionally substituted aliphatic radical with up to 8 carbon atoms, a cycloalkyl radical with 3 to 6 carbon atoms or a substituted phenyl radical which possess fungicidal properties and are produced by reacting a dichloromaleic acid halide of the formula ##STR2## in which X is halogen with an amine of the formula H.sub.2 N--R in a diluent and in the presence of an acid-binding agent.
本发明涉及公式为##STR1##的二
氯马来酸二酰胺,其中R代表可选取代的具有8个碳原子以下的脂肪基,具有3至6个碳原子的环烷基或取代的苯基,具有杀菌性能,是通过在稀释剂和酸中和剂的存在下,将公式为##STR2##的二
氯马来酸酰
氯与公式为H.sub.2 N--R的胺反应而制得的。
