Abstract
Maqolada mahalliy xomashyo - paxta moyi rafinatsiyasi (soapstok) dan ajratilgan yog‘ kislotalari asosida noionogen deemulgatorlar sintez qilish natijalari keltirilgan. Yog‘ kislotalarining o‘rtacha molekulyar massasi 274,9 g/mol, kislota soni 204,1 mg KOH ni tashkil etdi. Dietanolamin bilan amidlash orqali molekulyar massasi 362,0 g/mol bo‘lgan alkanolamid 93,4 % unum bilan olindi, kislota sonining 204,1 dan 4,2 mg KOH/g gacha kamayishi konversiya darajasi 97,9 % ekanini ko‘rsatdi. Alkanolamidni 10, 15 va 20 mol etilenoksid bilan oksietillash natijasida molekulyar massalari mos ravishda 802,5, 1022,7 va 1243,0 g/mol, gidrofil-lipofil balansi 10,98, 12,92 va 14,18 bo‘lgan DE-1, DE-2 va DE-3 namunalari sintez qilindi. HLB qiymati 12,9 bo‘lgan DE-2 namunasi optimal ekani aniqlanib, u 50 g/t sarfda va 80 °C haroratda 97,0 % suvsizlanish darajasini taminlagan, qoldiq suv miqdorini 0,18 mass. % gacha, qoldiq tuz miqdorini 42 mg/l gacha kamaytirishga erishilgan.References
