Abstract: p-tert-Butylcalix[4]arene was synthesized by p-tert-butylphenol and aldehyde using alkali as catalyst.An appropriate amount of ethyl acetate was added as a water carrier and the diphenyl ether was recycled as solvent.A mount of ethyl acetate and recycle times of diphenyl ether which effect on the yield of product were investigated.The results show that the addition of ethyl acetate can make the products yield increase,the dehydration time shorten and the reaction controleasily.Recycle times of diphenyl ether has significant effect on the products yield.The yield increased to 73% whendiph enylether was reused 3 times.The improved method can shorten reaction time and increase the yield of products.In addition,the effect of the catalyst K₂CO₃  amount on the yield of tetraethyl p-tert-butylcalix[4]arene tetraacetate were discussed.The result shows that the yield of the product can reached 74% when the optimal mole ratio of p-tert-butylcalix[4]arene to catalyst K₂CO₃  was1∶11.
