丙酮可用作分散染料的中间体,也是一种基本化工原料。用常规定氯法分析其纯度,由于多氯化合物的存在而受干扰,不易测准。本文研究用气相色谱法代替常规定氯法作为氯丙酮生产的控制分析方法和产品质量检测方法。实验结果说明,此法准确度好,精确度高,可以采用。一、气相色谱条件的选择丙酮由丙酮在加热等条件下通氯制得。反应产物中除1-氯丙酮(简称氯丙酮)外,还有1,1-二氯丙酮和1,3-二氯丙酮等多氯化合物。产物中的氯丙酮的含量,用常规定氯法分析,由于多氯化合物的存在而受干扰。考虑到反应
Acetone can be used as a disperse dye intermediates, but also a basic chemical raw materials. With conventional determination of its purity chlorine, due to the presence of polychlorinated interference, difficult to align. This paper studies the use of gas chromatography instead of the conventional determination of chlorine as a method of production of chloroacetone control analysis and product quality testing methods. Experimental results show that this method is accurate, high accuracy, can be used. First, the choice of GC conditions Acetone from acetone in the heat and other conditions through the chlorine obtained. Reaction products in addition to 1-chloroacetone (referred to as chlorine acetone), there are 1,1-dichloro-acetone and 1,3-dichloro-acetone and other polychlorinated compounds. The content of chloroacetone in the product, as determined by the conventional method of determination of chlorine, is disturbed by the presence of polychlorinated compounds. Take into account the reaction
