Beschreibung
Zusammenfassung:	Formulations comprising an asphaltene-dispersing/-inhibiting additive based on oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides Said formulations can contain: inert organic solvents, preferably including toluene, mixtures of xylene, o-xylene, p-xylene, kerosene, turbo fuel; inert hydrocarbon solvents having boiling points within the range of gasoline and diesel; or inert organic hydrocarbon solvents having a boiling point between 75 and 300 DEG C. The weight ratio of inert organic solvents to additive, which prevents and controls the precipitation and deposition of asphaltenes, varies between 1:9 and 9:1, but is preferably between 1:3 and 3:1. La presente invención se relaciona con formulaciones de aditivo inhibidor dispersante de asfaltenos a base de oxazolidinas derivadas de polialquil o polialquenil N- hidroxialquil succinimidas. Estas formulaciones pueden contener solventes orgánicos inertes, entre los cuales se encuentran preferentemente: tolueno, mezclas de xileno, o-xileno, p-xileno, queroseno, turbosina; o solventes hidrocarbonados inertes que tengan puntos de ebullición que se encuentran en el intervalo de la gasolina y el diesel; o solventes hidrocarbonados u orgánicos inertes cuyo punto de ebullición se encuentren en el intervalo de 75 a 300ºC. La relación en peso de solventes orgánicos inertes a aditivo que previene y controla la precipitación y depositación de asfaltenos varía de 1:9 a 9:1, preferentemente de 1:3 a 3:1.
