Synthesis and characterization of cyclohexanone-isobutyraldehyde resin
摘要
Abstract
Cyclohexanone-isobutyraldehyde resin was synthesized by condensation of cyclohexanone and isobutyraldehyde with sodium methylate as catalyst.The effect of molar ratio of materials,the amount of catalyst and reaction time on hydroxyl value,kinematic viscosity and yield of cyclohexanone-isobutyraldehyde resin was studied.FT-IR and 1H-NMR were used to characterize the structure of the resin.It was found that cyclohexanone-isobutyraldehyde resin with hydroxyl value of 43.60 mg KOH/g,kinematic viscosity of 7.78 mm2/s and yield of 52.3% was prepared when the molar ratio of isobutyraldehyde and cyclohexanone was 1.3,the amount of catalyst was 6.0 wt % and reaction time was 9 h,it exhibits better solubility in apolar solvents and yellowing-resistance than cyclohexanone-formaldehyde resin.The FT-IR and 1H-NMR results showed that the α-H of cyclohexanone reacted with isobutyraldehyde.关键词
