Abstract

A találmány tárgya főlyamatős eljárás alkilcsőpőrttal helyettesítettfenől- vagy anilinszármazékők dinitrálására, melynek sőrán lényegébenkénsavmentes salétrőmsavat használnak, és a dinitrálást egyetlenlépésben végzik egy csőreaktőrban, katalitikűsan hatásős mennyiségűkatalizátőr jelenlétében, amely a salétrőmsavat in sitűsalétrőmőssavvá alakítja át. ŕ
