The invention relates to a method for carrying out condensation reactions by heterogeneous catalysis using a surface-reacted calcium carbonate catalyst and to the use of dried surface-reacted calcium carbonate as a catalyst. The condensation reaction involves reacting a first substrate comprising a C = O double bond and a second substrate comprising active hydrogen to obtain a reaction mixture comprising one or more condensation products and one or more condensation by-products. 本发明涉及通过使用经表面反应碳酸钙催化剂的多相催化进行缩合反应的方法以及干燥的经表面反应碳酸钙作为催化剂的用途。缩合反应涉及使包含C＝O双键的第一底物和包含活性氢的第二底物反应以获得包含一种或多种缩合产物和一种或多种缩合副产物的反应混合物。
