401有机担体填充柱 测定化学试剂 乙醇(无水乙醇)的详细资料

测定化学试剂 乙醇(无水乙醇)
测定化学试剂 乙醇(无水乙醇) 详细信息:


名称:填充柱

规格:3m*3mm(内径)

粒度:0.18mm-0.25mm(60-80目)

型号:401有机担体

应用:GB/T 678-2002 化学试剂 乙醇(无水乙醇)

GB/T 678-2002 化学试剂 乙醇(无水乙醇)


代替GB/T 678-1990 化学试剂 无水乙醇 (已作废)



本标准规定了化学试剂 乙醇(无水乙醇)的技术要求,试验方法,检验规则和包装及标志.

共沸法生产无水乙醇的技术方法,是通过向普通的酒精中添加夹带剂(如苯),利用普通的蒸馏塔设备进行精馏。由于设备流程和加工工艺的不同,生产的无水乙醇的纯度是不同的,研究采用"恒沸蒸馏-苯回收蒸馏-酒精回收蒸馏"三塔流程技术,可使成品无水乙醇含量超过99.8%vol。

浩瀚色谱(山东)应用技术开发有限公司研发的401有机担体填充柱,柱效高,分离好,甲醇,乙醇,异丙醇得到有效分离,结果准确。

Determination of chemical reagents ethanol (absolute ethanol)
Determination of chemical reagents ethanol (absolute ethanol) Details:


Name: Packed column

Specification: 3m*3mm (inner diameter)

Granularity: 0.18mm-0.25mm (60-80 mesh)

Model: 401 Organic Carrier

Application: GB/T 678-2002 chemical reagent ethanol (absolute ethanol)

GB/T 678-2002 Chemical reagent ethanol (anhydrous ethanol)



Replace GB/T 678-1990 chemical reagents, absolute ethanol (obsolete)



This standard specifies the technical requirements, test methods, inspection rules, packaging and marking of the chemical reagent ethanol (absolute ethanol).

The technical method of azeotropic production of absolute ethanol is to add an entrainer (such as benzene) to ordinary alcohol and use ordinary distillation tower equipment for rectification. Due to the difference in the equipment process and processing technology, the purity of the absolute ethanol produced is different. The research adopts the "azeotropic distillation-benzene recovery distillation-alcohol recovery distillation" three-tower process technology, which can make the finished product absolute ethanol content exceed 99.8% vol.

The 401 organic carrier packed column developed by Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has high column efficiency and good separation. Methanol, ethanol, and isopropanol are effectively separated, and the results are accurate and reliable.
