The use the organicity colloid dispersing element of the iron grain, as an additive of the preparation manner and the engine fuel for the internal combustion engine

摘要

As for colloid dispersing element of this invention, organic phase; The particle of the iron compound which is amorphous form; And it features that at least the parents crocking characteristic substance of 1 kinds is included. As for this dispersing element, the iron salt under existing of the iron complexing agent and the base or the iron complex and the base, while maintaining the pH of reaction medium at value of at the most 8, reacting, obtaining precipitation, (as for the aforementioned iron complexing agent, it is selected from the water soluble carboxylic acid which possesses the complexation kind of constant K where pK at least becomes with 3, the aforementioned iron complex is selected from the reaction product of the iron salt and the aforementioned acid); Coming after, making the suspensoid contact which contains precipitation or the said precipitation which is obtained with organic phase under existing of the parents crocking characteristic substance, it is manufactured by the method of obtaining the dispersing element in organic phase. To use as the combustion additive in the liquid fuel or the engine fuel it is possible the dispersing element of this invention.
