overview

epoxy resin is widely used in coating materials, molding compounds and adhesives due to its high mechanical strength, good adhesion and processing properties. However, the low elongation at break and high brittleness of epoxy resin have prompted researchers to conduct extensive chemical or physical modification research. 4-fluoro-4'-hydroxybiphenyl can be used as a raw material, and 1, 4-butanediol, 1, 6-hexanediol, toluene diisocyanate (TDI), dimethylamine, epichlorohydrin The synthesis of a biphenyl type liquid crystal epoxy compound (LCE).

preparation

add 0.045 molTMBP(10g), 0.32 mol pyridine (8 mL) and 100 mL acetone to a 500 mL three-neck bottle with stirring, thermometer and 100 mL dropping funnel, dissolve 0.1 mol ABC(18g) in 30 mL acetone, pour into a dropping funnel and slowly drop into the three-neck bottle. The reaction was carried out in an ice-water bath for about 1 h until the dropping of ABC acetone solution was completed, and then the reaction was carried out at room temperature for 8 h. After the reaction, excess ice water is added to the mixture to produce a large amount of precipitation, filtration, chloroform/water volume ratio (1:1), mixed solvent washing and recrystallizing, drying in a vacuum oven and obtaining a yellow powder. Its structure was characterized by FT-IR and NMR spectra and determined as BABTMBP(P1).
