Abstract
Ushbu ishda p-toluolsulfonilsemikarbazidni sintez qilish va olingan mahsulotning IQ hamda UB spektral xususiyatlarini baholash amalga oshirildi. Maqsadli birikma p-toluolsulfonilmochevinani 80% li gidrazin gidrat bilan absolyut etanol muhitida 78–80 °C da qizdirish orqali olindi. Reaksiya yupqa qatlamli xromatografiya yordamida nazorat qilindi va 6 soat davom etgan jarayondan so‘ng mahsulot 59,5% unum bilan ajratildi. Bruker INVENIO X qurilmasida olingan IQ spektrda 3495,99; 3117,97; 3057,51; 2925,66; 2909,41; 2835,90; 1597,97; 1538,05; 1309,06; 1181,21; 1161,21 hamda 879,52–705,99 sm⁻¹ sohalarda diagnostik yutilishlar qayd etildi. Ular N–H/NH₂, aromatik C–H, metil guruhi, aromatik skelet hamda SO₂/C–N/S–N fragmentlari mavjudligi bilan muvofiq keladi. UV–Vis spektrida λmax ≈229 nm da asosiy yutilish maksimumi kuzatildi. Olingan natijalar sintez mahsulotining p-tolil-sulfonilsemikarbazid tizimiga xos spektral belgilarini ko‘rsatdi.References
