摘要
为配合酚醛树脂、十八烷基苯乙烯基醚聚合物新材料的生产、催化条件下煤直接液 化的研究，建立了各试样分子量表征的高效凝胶渗透色谱法（ＨＰＧＰＣ），高分辨地测定了分子 量分布、重均分子量Ｍｗ、数均分子量Ｍｎ。表征了不同产品的组成特性，有效地指导了工艺生
A high performance gel permeation chromatographic (HPGPC) method was developed for the molecular weight and molecular weight distribution determination of chemical products including phenolic resin, polymer of octadecyl-styrenyl-ether and heavy asphaltene from coal liquefaction. The GPC column (50 cm × 0.79 i. d. ), was Packed with HSG-15 support. For the analysis of phenolic resin, polymer and catalytic liquefaction of coal, the mobile phase was tetrahydrofuran0. 8 mL/min,chloroform at 1. 2 mL/min and tetrahydrofuran at 0 .9 mL/min, respectively. The GPC calibration curves can be expressed as logM = 4.52848 - 0.08577t, logM = 4.53991 - 0. 14428t and logM = 5 .0936 - 0. 1095t for resin, polymer and catalytic liquefaction of coal, respectively.
