叔胺催化剂是广泛应用于聚氨酯工业的两种催化剂之一。其合成中往往生成影响聚氨酯制品性能的仲胺副产物。利用H-NMR法测定了叔胺催化剂中仲胺基的含量。结果准确度与仪器积分准确度相同,误差约1％。 Tertiary amine catalysts are one of the two catalysts widely used in the polyurethane industry. The synthesis of secondary amine products often affect the performance of polyurethane products. The content of secondary amine groups in the tertiary amine catalyst was determined by H-NMR. The accuracy of the results is the same as that of the instrument, with an error of about 1%.
