Abstract
"PROCESSO PARA A PREPARAçãO DE UM COMPOSTO". A presente invenção refere-se a um processo para a síntese de piridinas tri- e tetra-alquiladas (isto é, colidinas) com alta capacidade de produção pela reação de metil etil cetona com formaldeído na presença de amónia em fase gasosa e um catalisador zeólito o qual compreende sílica alumina com pelo menos um íon de metal e/ou um metal selecionado a partir do grupo consistindo de lantânio, chumbo, manganês, ferro, cobre e cobalto. Este processo resulta em uma produção não prejudicial ao meio-ambiente, mais económica e seletivamente heterogênea quanto a formato.
