    摘要: Method for making methylene-bis-diorganophosphorodithiato-substituted hindered phenols by conversion of hindered phenols to the corresponding hindered phenol aldehydes and subsequent reaction, without isolation, with a diorganophosphorodithioic acid, which results in economically advantageous and simplified processing as well as minimization of wasteful and costly by-products.
