Fast determination butane,butanone,acetic acid isopropyl by headspace sampling gas chromatography;
顶空气相色谱法快速测定水中正丁烷、丁酮、醋酸异丙酯
This paper introduced the a defermination of butane,butanone,acetic acid isopropyl ester in the air by capillary gas chromatography.
采用活性炭吸附,二硫化碳解析,毛细管气相色谱法同时测定空气与废气中的正丁烷、丁酮、醋酸异丙酯,采样体积以45 L计,方法最低检出限分别为:正丁烷0。
It is pointed out that developing of maleic anhydride using the butane source of Luoyang Petrochemical Branch Company can not only enhance the added value of liquified petroleum gas,but also change the present situation of no maleic anhydride installment in the Yellow River area,promote the fine chemical developme.
介绍了顺酐的主要生产方法和技术进展,分析了我国顺酐工业的生产现状、消费情况,提出用洛阳石化分公司现有的正丁烷资源开发顺酐产品,既能提高液化石油气的附加值,又可以改变中原地区没有大型顺酐装置的现状,促进中部精细化工的发展,具有显著的经济效益和社会效益。
