Abstract
p-Fenilendiamin va p-dimetilaminobenzaldegidning kondensatsiyasi orqali sintez qilingan N,N′-bis(4-(dimetilamino)benziliden)-1,4-fenilendiamin (SB-1) ning St20 uglerodli po‘lat korroziyasiga qarshi himoya xossalari o‘rganildi. Birikmaning sintez yo‘li va strukturaviy xususiyatlari, 1,0 M HCl muhitidagi gravimetrik hamda potentiodinamik polarizatsiya natijalari, shuningdek po‘lat sirtining makroskopik va atom- kuch mikroskopik holati o‘zaro bog‘liq holda tahlil qilindi. 150 mg·L⁻¹ SB-1 mavjudligida potentiodinamik polarizatsiya bo‘yicha himoya samaradorligi 95,79% ga yetdi. Gravimetrik tajribalarda shu konsentratsiyada 303–333 K oralig‘ida 91,96–95,18% himoya samaradorligi qayd etildi. Natijalar azometin va dimetilamino azot markazlari hamda konyugatsiyalangan aromatik π-tizimning metall–eritma chegarasidagi adsorbsion o‘zaro ta’sirlarga hissa qo‘shishi mumkinligini ko‘rsatadi.References
