The solid base derived from abundant waste slag was prepared by co-precipitation method, and tested in the diethyl carbonate synthesis via ethanolysis of ethyl carbamate. Compared to the previous reports, much higher catalytic activity and turnover frequency (TOF) of 2926 mg(DEC)/g(cat) center dot h(-1) could be achieved. Accordingly, the correlation between the catalyst basic properties and the catalytic performance revealed that the appropriate strong basic sites facilitated the formation of DEC. Moreover, the catalyst could be readily recycled and reused for several times through facile calcination. (C) 2014 Published by Elsevier B.V.
