The test criteria of ASTM D2887 and ASTM D86 for distillation range is one of the important research area in gas chromatography.For correlation modeling the generalization and robustness is also the major target to evaluate.In this paper a modeling method based on the weighted mean-square deviation and variance optimization is proposed.This method is used in Engler boiling range distribution measurement which usually calculated by ASTM means

to calibrate the coefficients of the original model by the value errors between the model prediction and laboratory analysis.Theory study，mathematical calculation and technology application verified the robustness and generalization property of this method.The application results indicated that the correlation modeling method of the chromatography distillation range and Engler boiling range can be used to the application of simulation distillation and a reliable analysis means for quickly measuring the oil distillation range.
