摘要：NOVELTY - Production of 1,4-diphenyl(ortho-cyano phenylethylene) is carried out by putting ortho-cyano benzyl chloride into closed reactor with condensing refluxing device at normal pressure, agitating at 100-110oC for 2-3 hrs, adding into trimethyl phosphite in proportion of ortho-cyano benzyl chloride: trimethyl phosphite =1:1, heating to 120-130oC while reacting for 2-3 hrs, cooling reactant to 20-30oC, adding into terephthalic aldehyde and solvent in proportion of terephthalic aldehyde: ortho-cyano benzyl chloride =1:2 mol, dripping into sodium ethylate alcohol solution with concentration 10-16 wt%,in 2-3 hrs, reacting, filtering to obtain reactant after 2 hrs, washing by alcohol and water separately and drying to obtain final product. It is simple and safe, has less consumption and more yields.
