Abstract

La presente invención se refiere a aditivos detergentes-dispersantes sobrealcalinizados para aceites lubricantes, caracterizados por que son obtenidos mediante: a) neutralización de un alquilfenol llevando uno o arios sustitutivos alquilos con 8 hasta 30 átomos de carbono, con ayuda de una base alcalinotérrea en presencia de un alcohol "vector".The present invention refers to over-alkaline detergent-dispersant additives for lubricating oils, characterized in that they are obtained by: a) neutralization of an alkylphenol by carrying one or more alkyl substitutes with 8 to 30 carbon atoms, with the help of an alkaline earth base in the presence of a "vector" alcohol.
