CRYSTALLINE COMPLEX COMPOUNDS OF MORPHOLINE DERIVATIVES WITH KETOACIDS AS CORROSION INHIBITORS, METHOD OF PREPARATION THEREOF, COATING COMPOSITION, AND CORROSION PROTECTION METHOD

摘要

FIELD: organic synthesis and corrosion protection. SUBSTANCE: crystalline complex compounds depicted by general formula 1: (1) are provided where R1,R2,R3,R4 and R5, independently, are halogen, C1-C15=-alkyl or C6-C10- aryl provided that at least one of R1-R5 radicals is hydrogen, halogen, or C1-C15-alkyl, R10 is C1-C15-alkyl, and m=2. Compounds can be used as corrosion inhibitors in metal surface coating compositions. Provided are also coating compositions, method for protection of metal substrate from corrosion, and method of preparing compounds. EFFECT: increased resource of corrosion protectors. 15 cl, 11 tbl, 12 ex
