摘要： The present invention provides a method of preparing a heterogeneous linear carbonate, the method including transesterifying an aliphatic alcohol and a symmetric linear carbonate in the presence of a catalyst, wherein the catalyst is an acidic ion exchange resin, and a mass ratio of the aliphatic alcohol and the symmetric linear carbonate (aliphatic alcohol:symmetric linear carbonate) is 1:10 or more and 50:1 or less. The preparation method of the present specification provides a method of preparing a heterogeneous, symmetric linear carbonate and asymmetric linear carbonate in high yield without a process of reactive distillation, and is economical because a product and a catalyst can be easily separated.
