OV-101 色谱级正庚烷的测定毛细管柱的详细资料

色谱级正庚烷的测定毛细管柱
色谱级正庚烷的测定毛细管柱 详细信息：

名称：毛细管柱

规格：50m*0.25mm

型号：OV-101

应用：GB 8120-1987高纯正庚烷和异辛烷纯度测定法 (毛细管色谱法)

浩瀚色谱（山东）应用技术开发有限公司研发一种色谱级正庚烷的生产方法，涉及化工技术领域。该方法包括如下步骤：向工业级正庚烷中加入混酸溶液，在搅拌条件下进行酸洗，然后静置分层；分离出下层酸液，然后加入碱液，在搅拌条件下对正庚烷进行碱洗，然后静置分层；分离出下层碱液，加入纯水洗涤洗涤液呈中性；然后静置分层；分离出下层水溶液，加入干燥剂进行干燥；然后过滤除去干燥剂；取滤液进行蒸馏，收集98‑100℃的产品即得。该方法通过酸洗、碱洗除去正庚烷中的杂质，通过清水洗涤残留的酸碱，并用干燥剂除去剩余的少量水分，蒸馏取特定温度下的馏分得到高纯度的正庚烷，该方法工艺简单，试剂成本低廉，并且除去杂质的同时不引入其他有机杂质，产品收率高。

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.
