Abstract

"SìNTESE DE éSTER". Processo para produzir éster alifático inferior, especialmente acetato de etila, pela reação de uma olefina inferior com um ácido mono-carboxílico alifático inferior saturado na fase de vapor usando um catalisador de heteropoliácido, onde a pressão da reação é de 11 a 20 barg (1100 a 2000 KPa), mais preferivelmente 12 a 15 barg (1.200 a 1.500 KPa) . A temperatura da reação é de 140 a 250<198>C, mais preferivelmente 160 a 195<198>C. O processo reduz o nível de subprodutos, por exemplo, metil etil cetona e/ou acetaldeído.
