▎ 摘　　要

NOVELTY - A catalyst for directionally synthesizing alkyl carbonate from alkyl oxalate comprises calcium-magnesium-aluminum hydrotalcite modified by modifier. USE - The catalyst is used in the reaction system for synthesizing alkyl carbonate from alkyl oxalate (claimed). ADVANTAGE - The modified calcium-magnesium-aluminum hydrotalcite alone has a good catalytic effect on the decarburization of alkyl oxalate to alkyl carbonate. The modified calcium-magnesium-aluminum hydrotalcite catalyst has high activity, good selectivity and is environmental friendly.
