Abstract
As a kind of chemical intermediate,2-Ethylhexyl chloroformate was used to synthesize bis-(2-ethylhexyl) peroxydicarbonate(EHP).EHP was highly active polymerization initiator.The synthesis method of reacting with 2-ethylhexanol and triphosgene had not been reported.In this paper,2-Ethylhexyl chloroformate was synthesized using 2-ethylhexanol and triphosgene as raw materials.The effect of adding matters sequence,reaction time,reaction temperature,kinds and content of catalysts on yield and purity of 2-ethylhexyl chloroformate was studied,and the optimized synthesis conditions were obtained.The structures of products were characterized.The EHP was successfully prepared using obtained 2-ethylhexyl chloroformate.
