摘　　要：用自动电位定位滴定法测定了进口原油的酸值。探讨了进口原油的酸值分布情况及酸值随沸点的变化规律。结果表明:低酸原油、含酸原油和高酸原油,其窄馏分的酸值随实沸点温度的变化规律基本一致;同一产地的原油,在不同的时间测定的酸值有较大的变化,但其窄馏分油的酸值随实沸点温度的变化趋势基本不变。Potentiomentric titration was used to test the acid valve of imported crude oil.Distribution of acid valve with boiling point was discussed as well.The research shows that the distribution law of acid valve in every distillate with boiling point is corresponding in different type imported crude oil.The acid valve have a large variation in different period of the same crude oil,but The Distribution law of acid valve in every distillate with boiling point is invariant.
