용도

Dimethyl carbonate is used as a solvent in organic synthesis and considered as a replacement for solvent like methyl ethyl ketone, tert-butyl acetate and parachlorobenzotrifluoride. It is involved as an intermediate in the preparation of diphenylcarbonate, which in turn is used as a key raw material for the synthesis of Bisphenol-A-polycarbonate. It is also used as a 'green' methylating agent involved in the methylation of aniline, phenols and carboxylic acids. It can be used as a fuel additive due to its high oxygen content. It also finds applications related to supercapacitors and lithium batteries.

참고

Air and moisture sensitive. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents, strong acids and strong bases.

Conversion of a ketone to its methoxycarbonyl derivative has been used to change the preferred site of chlorination to the less-substituted carbon atom: Synthesis, 188 (1987):

Grignard reagents react in THF to give methyl esters, providing a high-yield, one-pot synthesis of carboxylic esters from alkyl or aryl halides: Synth. Commun., 20, 3273 (1990).

Useful alkylating agent. Although less reactive, dimethyl carbonate has the advantage of much lower toxicity than the more usual sulfate or iodide. In the presence of K2CO3 and 18-crown-6, alcohols, phenols, thiols, imidazoles, etc. can be methylated: Synthesis, 382 (1986). For K2CO3 promoted alkylation of active methylene compounds at 180-220o (pressure), see: Rec. Trav. Chim., 115, 256 (1996); Org. Synth., 76, 169 (1998). Other dialkyl carbonates behave similarly.
