摘要
对工业萘分步结晶法制精萘温度区段的划分、降温速率对精萘结晶点的影响和萘中各类杂质对酸洗比色的影响进行了阐述 ,并列举了国内外几家工厂生产工艺技术经济参数 ,为精萘质量的提高提供参考。
The present paper described effects of partition of the temperature sections in refining the pure naphthalene by stepped crystallizaion process and rate of temperature fall on the crystallization point of pure naphthalene as well as effects of impurities of various kinds in the naphthalene on acid washing colorimetric analysis,and provided parameters of process,technology and economy of certain factories at home and abroad as reference for improvement in the quality of pure naphthalene.
