本文应用色谱—质谱联用方法对广州口岸从国外进口的一批正丁醇原料进行了杂质分析。采用的仪器为西德MAT 311 A-VARIAN1440型气相色谱—质谱联用仪。经色谱—质谱联用分析,确定了二批试样中的杂质成份和含量。广西[3]号含正丁醇51.6％,乙酸乙烯酯40.2％,乙酸丁酯8.2％,广州[1]号含正丁醇64.6％,乙酸丁酯3.4％,二丁醚32％。外贸部门根据以上科学数据,向外商交涉,得到了索赔。
In this paper, a batch of n-butanol raw materials imported from abroad at Guangzhou Port were analyzed by means of chromatography-mass spectrometry. The instrument used was West Germany MAT 311 A-VARIAN1440 GC-MS. By chromatography - mass spectrometry analysis, two batches of samples to determine the impurity components and content. Guangxi [3] contains n-butanol 51.6%, vinyl acetate 40.2% and butyl acetate 8.2%. Guangzhou [1] contains 64.6% of n-butanol, 3.4% of butyl acetate and 32% of dibutyl ether. According to the above scientific data, the foreign trade department has made a claim to foreign investors.
