FIELD: industrial organic synthesis. SUBSTANCE: derivatives with general formula I: <EMI ID=0.480 HE=21 WI=36 TI=CHI> (I), where R' are alkyl groups - statistical mixture of homologs and isomers with average C atoms' number 1 to 30, R" hydrogen or C<SB>1</SB>-C<SB>3</SB>-alkyl, A C<SB>2</SB>-C<SB>10</SB>-1,2-alkylene, and p integer from 3 to 50, are prepared by epoxide-oxyalkenylation of N-substituted hexahydropyrimidines with general formula II: <EMI ID=0.481 HE=21 WI=21 TI=CHI> (II). Compounds I are excellent corrosion inhibitors for water-in-oil emulsions. EFFECT: increased corrosion-protection activity. 8 cl, 4 tbl, 10 ex
