各位虫友帮忙翻译1段话，谢谢！

| In its essentials my process comprises treating petroleum or a fraction thereof containing one or more nitrogen bases with a volatile acid or a nonvolatile acid salt together with a mutual solvent for the acid and hydrocarbon to effect the improved recovery of the nitrogen base。It has been postulated that one reason for the comparatively inefficient separation of nitrogen bases from hydrocarbons is because of the poor solubility of the reagents normally employed in the extraction。I have found that this difficulty may be overcome by combining with the extractive solvent a mutual solvent which has the effect of increasing the solubility of the extractive solvent in the hydrocarbon resulting in improved recovery of the nitrogen bases。 |

In its essentials my process comprises treating petroleum or a fraction thereof containing one or more nitrogen bases with a volatile acid or a nonvolatile acid salt together with a mutual solvent for the acid and hydrocarbon to effect the improved recovery of the nitrogen base。It has been postulated that one reason for the comparatively inefficient separation of nitrogen bases from hydrocarbons is because of the poor solubility of the reagents normally employed in the extraction。I have found that this difficulty may be overcome by combining with the extractive solvent a mutual solvent which has the effect of increasing the solubility of the extractive solvent in the hydrocarbon resulting in improved recovery of the nitrogen bases。 就其要点，我的处理过程包括石油加工或者是其中的一部分，在这其中包含一或更多的氮基，通过对于酸或碳氢化合物有互溶作用的一种挥发性酸或非挥发性酸式盐，可以改进的氮基的回收率。由于在分离过程中，一般被使用的试剂溶解性差，可以推测出这是氮基从烃类中分离出来效率差的原因之一。我已经发现，可以通过将萃取剂与一种互溶剂相混合，这样可以提升萃取剂在碳氢化合物中的溶解度，从而改善氮基的回收率。 |
