产品介绍：有芳香气味。对湿敏感。化学性质较不稳定，在湿空气存在下能水解，生成草酸或酸性草酸乙酯。能与醇、醚和其他有机溶剂混溶，微溶于水而渐渐分解，有刺激性。溶剂，有机合成，能从乙二酸盐均匀溶液中析出稀土及其他元素。应用 草酸二乙酯被用于ZnO纳米颗粒的微乳液合成。它还被用于合成 对称-1,4-二苯基-1,4-二氢-1,2,4,5- 聚四吖嗪。 Diethyl oxalate undergoes transesterification with phenol in the liquid phase over very efficient MoO3/TiO2 solid-acid sol-gel catalysts to form diphenyl oxalate. It undergoes Claisen condensation with active methylene group of ketosteroids to form glyoxalyl derivatives. It undergoes hydrogenation in the presence of high copper contented mesoporous Cu/SBA-15 catalysts to yield ethylene glycol.Diethyl oxalate is used to prepare active pharmaceutical ingredients (API), plastics and dyestuff intermediates. It is also used as a solvent for cellulose esters, ethers, resins, perfumes and lacquers for electronics. It is involved in the transesterification reaction with phenol to get dipheny oxalate. It is also involved in the Claisen condensation ketosteroids to prepare glyoxalyl derivatives. Further, it is used to prepare sym-1,4-diphenyl-1,4-dihydro-1,2,4,5-polytetrazine. In addition to this, it is utilized in the microemulsion synthesis of zinc oxide nanoparticles.
