Determination of chromatographic grade n-heptane capillary column
Capillary column for the determination of chromatographic grade n-heptane Details:
Name: Capillary Column
Specification: 50m*0.25mm
Model: OV-101
Application: GB 8120-1987 High-purity n-heptane and isooctane purity determination method (capillary chromatography)
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a method for producing chromatographic-grade n-heptane, which involves the field of chemical technology. The method includes the following steps: adding a mixed acid solution to industrial-grade n-heptane, pickling under stirring conditions, and then standing for stratification; separating the lower layer of acid solution, then adding lye, and reacting to n-heptane under stirring conditions. Carry out alkaline washing, then stand for layering; separate the lower layer of lye, add pure water to wash until the washing liquid is neutral; then stand for layering; separate the lower layer of aqueous solution, add a desiccant to dry; then filter to remove the desiccant; Take the filtrate for distillation, and collect the product at 98-100°C. This method removes impurities in n-heptane by pickling and alkali washing, washing the remaining acid and alkali with clear water, and removing the remaining small amount of water with a desiccant, and distilling the fraction at a specific temperature to obtain high-purity n-heptane. This method The process is simple, the reagent cost is low, and other organic impurities are not introduced while removing impurities, and the product yield is high.
