  In the hydroformylation of a compound having a carbon-carbon double bond with formation of alcohols and/or aldehydes in the presence of a transition metal (e.g. cobalt) carbonyl phosphine (or arsine, stibine) complex catalyst, deposition of transition metal on walls is considerably reduced and the catalyst is rendered considerably more stable by the presence of a dissolved salt of an alkyl-substituted arylsulphonic acid salt.

  在使用过渡金属（如钴）羰基膦（或胂、锡丁）络合物催化剂对具有碳碳双键的化合物进行加氢甲酰化反应并形成醇和/或醛的过程中，过渡金属在壁上的沉积会大大减少，而烷基取代的芳基磺酸溶解盐的存在会使催化剂变得更加稳定。
