Abstract

Patente de Invenção: <B>"APARELHO E PROCESSO PARA PRODUZIR áCIDO (MET)ACRìLICO"<D>. A presente invenção provê um aparelho para produzir ácido (met)acrílico e um processo para produzi-lo com este aparelho, em que o aparelho permite a produção do ácido (met)acrílico estavelmente por um longo período de tempo pela inibição efetiva da polimerização de ácido (met)acrílico em seu processo de produção (por exemplo, em um refervedor). Pelo menos uma parte do aparelho é feita de uma liga de níquel-cromo-ferro com um teor de molibdênio de 3 a 20 % em massa, mas não incluindo 3 % em massa, ou com um teor de molibdênio de 1 a 4 % em massa e um teor de cobre de 0,5 a 7 % em massa.
