Abstract
DETERGENTES DE MANNICH PARA COMBUSTìVEIS HIDROCARBÈNICOS. A presente invenção refere-se a novos detergentes de Mannich altamente eficazes, para uso em combustíveis hidrocarbónicos, que reduzem depósitos de motores, em motores de combustão interna com ignição a centelha e por compressão. Eles são produtos da reação de condensação de Mannich, obtidos reagindo (i) uma poliamina que tem um grupo amina primária estericamente impedida, (ii) um composto hidróxi-aromático substituído com hidrocarbila, e (iii) um aldeído. Estes compostos detergentes de Mannich podem ser dispersados em um veículo líquido, para produzir um concentrado de aditivos para combustíveis, para combustíveis hidrocarbónicos de motores de combustão, que controlam eficazmente a formação de depósitos no motor, nas válvulas de admissão e outros regiões do motor, tais como injetores de combustível com orifícios e câmaras de combustão.
