Abstract
<B>PROCESSO PARA SìNTESE DE éSTERES<D>. A presente invenção refere-se a um processo para a produção de ésteres alifáticos inferiores unindo em uma reação de adição, uma olefina inferior e um ácido monocarboxílico, alifático inferior, saturado na fase de vapor em contato com um catalisador heteropoliácido caracterizado pelo fato de que a olefina reagente e ácidos e quaisquer alimentações recicladas são tornadas substancialmente isentas de impurezas de aldeído antes de serem colocadas em contato com o catalisador heteropoliácido. Acetaldeído é um veneno catalítico e a remoção deste das alimentações prolonga a vida e atividade do catalisador heteropoliácido.
