An effective synthetic method for unsymmetrical carbonate species has been developed. Calcium oxide and calcium hydroxide were found to be highly effective for this reaction, affording unsymmetrical carbonates in high yield and purity. Calcium chloride, which is a coproduct, serves as a water scavenger that can be easily removed. Additional drying processes and complicated purification steps are not necessary in this reaction. This improved process is important in terms of green sustainable chemistry principles.

Paragraph 0110; 0111; 0119-0139, (2020/04/01)
The invention relates to the field of diphenyl carbonate synthesis, and discloses a diphenyl carbonate compound preparation method, which comprises: in the presence of a catalyst represented by a formula (1-1) or a formula (1-2), carrying out a transesterification reaction on a phenol compound represented by a formula (II) and a diester carbonate compound represented by a formula (III), wherein R1, R2 and R3 are selected from a C1-C14 aliphatic hydrocarbon group, a C3-C14 cycloalkyl group, a C6-C14 aryl group, a C7-C14 alkylaryl group, a C7-C14 aralkyl group and a C10-C14 condensed ring aryl group, and X is halogen. The method is high in catalytic activity, high in selectivity and good in stability. Formula (1-1) is (H-[O-Si-(R1)2]n-O)x1-Ti-(OR3)y1X(4-x1-y1), and formula (1-2) is [Si(R2)xO]x2-Ti-(OR3)y2X(4-x2-y2).
