羧酸镧作为车用汽油抗爆剂的研究

STUDY ON CARBOXYLIC LANTHANUM AS GASOLINE ANTIKNOCKS

探讨了稀土化合物用作环保汽油抗爆剂的可能性。合成的羧酸镧抗爆剂试验研究显示 :此类化合物具有较好的油溶性和一定的抗爆性 ,加入量为 ( 1～ 4)× 10 - 3mol/L ,MON可提高一个单位左右。不增加汽油的腐蚀性 ,能够作为汽油抗爆剂使用 。

Capabilities using rare earth compounds as environmentally friendly gasoline antiknocks were explored.Test results showed that the carboxylic lanthanum compounds have better oil solubility and certain antikonck property.The MON of gasoline can be enhanced by 1 unit by adding (1～4 )×10 -3 mol/L of carboxylic lanthanum without increasing corrosivity of gasoline.As one of the gasoline antiknocks,carboxylic lanthanum has better prospects of development and application.
