Abstract

A találmány tárgya eljárás 4'-klór-4-bifenil-karboxaldehidtisztítására, amelynek során e) a 4'-klór-4-bifenil-karboxaldehidetnátrium-biszulfittal reagáltatják egy olyan vizes/acetonitrilesközegben, amelynek acetonitril-tartalma elegendő ahhoz hogy biszulfit-addukt csapódjon ki, f) a biszulfit-addukt csapadékot az oldatbólizolálják, g) az izolált biszulfit-adduktot egy olyanvizes/acetonitriles oldattal keverik össze, amelynek víztartalmaelegendő ahhoz, hogy a regenerált aldehid kicsapódjon, és h) abiszulfit-adduktot 4'-klór-4-bifenil-karboxaldehiddé alakítják.
