    Abstract: A catalyst useful for the condensation of an aldehyde or ketone starting material with a phenol is an insoluble mercaptosulfonic acid compound. The heterogeneous catalysts comprise catalytically-active species represented by formula (a). L is an optional linking group and is a bond, which catalytically active species is attached by the bond to an insoluble organic or inorganic support; or a catalytically-active species represented by formula (b), wherein L' is an optional linking group, is a bond and theta ' and theta '' are residues of theta , and a and b are independently selected from integers equal to or greater than 1.

    Abstract translation: 用于醛或酮原料与苯酚缩合的催化剂是不溶性巯基磺酸化合物。 非均相催化剂包含由式(a)表示的催化活性物质。 L是任选的连接基团,并且是键,其中催化活性物质通过键连接到不溶性有机或无机载体上; 或由式(b)表示的催化活性物质,其中L'是任选的连接基团,是键,θ'和θ“是θ的残基,a和b独立地选自等于或大于 比1。
