Abstract:1-Chloroethylisopropyl carbonate, with 1-methylethylethanoate as solvent, tetrabutylammonium bromide as phase transfer catalyst and calcium chloride as desiccant, was directly reacted with sodium iodide to obtain 1-iodoethylisopropyl carbonate with a purity of 93% (area%) and a molar yield of 74%. This method is easy to operate; the solvent is easy to recover; the cost is low; and the purity of the product is high. All above indicates this method is suitable for industrial production. |
Key words:1-iodoethylisopropyl carbonate; 1-chloroethylisopropyl carbonate; synthesis |
