FIELD: organic chemistry. SUBSTANCE: additive to crude oil, namely deemulsifier, corrosion inhibitor and/or addition agent for reducing solidification temperature. Oxalkylated fatty amines and fatty amine derivatives of formula I: <EMI ID=0.150 HE=12 WI=66 TI=CHI> wherein A is residue of formulae II-V, R is C<SB>6</SB>-C<SB>22</SB>-alkyl or C<SB>6</SB>-C<SB>22</SB>-alkylene; X is integer from 5 to 40; Y is integer from 3 to 70; Z is from 0 to 70 wt ethylene oxide based on weight of compound of formula I having ethylene X oxide units and propylene Y oxide units. Compounds I are prepared by reacting amines II-V with ethylene oxide and propylene oxide in the presence of bases. Compounds I retard substantially paraffin deposition. EFFECT: improved properties of the title compounds. 2 cl, 4 tbl <EMI ID=0.151 HE=12 WI=24 TI=CHI>, <EMI ID=0.152 HE=18 WI=27 TI=CHI>, <EMI ID=0.153 HE=15 WI=27 TI=CHI>, <EMI ID=0.154 HE=21 WI=27 TI=CHI>,
