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: 
wherein A is residue of formulae II-V, R is C6-C22-alkyl or C6-C22-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
