摘要
FIELD: chemical industry. SUBSTANCE: described are Schiff bases of formula I, II and III, wherein R1 is H; R2 is CH2N(CH3)2; R3 is H, o-CH3, n-CH3, o-CH3, n-OCH3, o-NO2, n-NO2, m-NO2, which are useful as epoxy resin hardening accelerators. Compounds I, II and III are prepared by reacting aromatic Schiff base of formula: (o-OH)C6H4-CH=N-C6H4-R3 with N,N-tetramethylmethylene bisamine in C1-C5 aliphatic alcohol at aromatic schiff base to bisamine to solvent molar ratio of 1:(2.1-2.5):(2.5- 10.0) at 18-120 C and pressure of 1-6 atm for 4-18 h. EFFECT: improved properties of the title compounds. 3 cl, 22 ex, 3 tbl 展开▼
