| Abstract: | Di-2-ethyhexyl carbonate was prepared by transesterifying dimethyl carbonate with 2-ethylhexanol in the presence of CaO/ZrO_2 solid base as a catalyst.XRD was used to characterize the structure of the catalyst.The experimental results showed that under the conditions of catalyst calcination temperature 873K,catalyst content 1.5(the percentage of total mass of the reaction solution and the yield of product still kept at 59.8 after the catalyst being used six times.Analysis of product by means of FTIR and HNMR showed that no by-product existed so the purity was high. |
