Title: Catalytic synthesis of 2-ethylhexyl chloroacetate by modified titanium sulfate
Abstract: A new type of solid acid catalysts was prepared by calcination of titanium sulfate at 450 ℃, and the acid property was characterized by IR spectra of pyridine absorbed on the surface. The catalytic activity was determined for synthesis of 2-Ethylhexyl chloroacetate. The results showed that the catalysts had Brnsted acid centers and the catalytic activity increased with modified of calcination. By esterification of chloroacetic acid with 2-ethylhexyl alcohol, and reaction conditions have been discussed. The yield of the ester could reach 95.8% under the amount of moler ratio of 2-Ethylhexyl alcohol to chloroacetic acid 1.1:1. Time of reaction was 90 min.Amount of catalyst was 2.5%.
