Ushbu tadqiqotda arilkarbonilmetilizoxinolin xloridlarga asoslangan yangi korroziya ingibitorlari sintez qilindi va neftni qayta ishlash tizimlarida qo‘llanilishi o‘rganildi. Ingibirlash samaradorligi namuna va model neft konlari oqava suvlarida elektrokimyoviy va gravimetrik usullar yordamida o‘rganildi. Natijalar korroziyani ingibirlash samaradorligining alkil zanjiri uzunligiga kuchli bog‘liqligini ko‘rsatdi. Maksimal samaradorlikka (79,8%) 10 ta uglerod atomini o‘z ichiga olgan birikma uchun erishildi, bu gidrofoblik va eruvchanlik o‘rtasidagi optimal muvozanatni ko‘rsatadi. Adsorbsiya tahlili shuni ko‘rsatdiki, ingibirlash jarayoni Lengmyur izotermasiga amal qiladi, bu esa metall yuzasida ingibitor molekulalarining monoqatlamli adsorbsiyasini ko‘rsatadi. Ingibirlash mexanizmi ham elektron effektlar, ham molekulyar tuzilish bilan boshqariladi, bu esa barqaror himoya plyonkasining hosil bo‘lishiga olib keladi. Sintez qilingan birikmalar neftni qayta ishlash va tashish tizimlari uchun samarali korroziya ingibitorlari sifatida yuqori samaradorlikka ega ekanligini ko‘rsatadi.
