Abstract
Tert-butyl bromoacetate ester was synthesized using bromoacetic acid and isobutylene as raw materials,Amberlyst 15,a strong acidic cation exchange resin,as catalyst,and tert-butanol as modifier.Through a series of orthogonal test,we investigated the optimal reaction time,reaction temperature and catalyst dosage,moreover,the inhibition of tert-butyl alcohol to isobutene polymerization and the effect of 5 kinds of solvents on the yield of product were also discussed.The optimal process conditions were determined as follows:dichloromethane as solvent,reaction time 6 h,reaction temperature 10 ℃,catalyst dosage 12 g,and tert-butanol 4 g.Under the above optimal conditions,the product yield is 94.2%.
