GB/T 2093-2011 Formic acid for industrial use
Replace GB/T 2093-1993
This standard specifies the product classification, requirements, test methods, inspection rules, labeling, packaging, transportation, storage, and safety of formic acid for industrial use.
This standard is applicable to industrial formic acid produced by methyl formate method and sodium formate method.
The use of physical and chemical titration method to determine the content of formic acid in the national standard has the following drawbacks:
Long analysis time, low efficiency, unable to meet the needs of industrial production testing
Requires a large amount of chemical reagents, pollutes the environment, and is not environmentally friendly
Affects the health of laboratory personnel
It is not easy to determine the purity of formic acid by gas chromatography, as formic acid has strong activity, low sensitivity, peak tailing, and corrodes the instrument. To this end, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a new technology called "Industrial Formic Acid Purity Determination New Technology Chromatographic Column" using a new method. It can directly inject samples to determine the purity of industrial formic acid without the need for sample conversion, with high efficiency and short analysis time. It has been installed and used on instruments such as Agilent, Shimadzu, Thermo Fisher Scientific, Varian, Brooke, and PE, and has achieved good results.

GB/T 2093-2011 工業(yè)用甲酸
代替GB/T 2093-1993
本標(biāo)準(zhǔn)規(guī)定了工業(yè)用甲酸的產(chǎn)品分類、要求、試驗方法、檢驗規(guī)則及標(biāo)志、包裝、運輸、貯存和安全。
本標(biāo)準(zhǔn)適用于甲酸甲酯法和甲酸鈉法生產(chǎn)的工業(yè)用甲酸。
?
國標(biāo)中采用理化滴定法測定甲酸的含量：存在以下缺點：
-
分析時間長，效率低下，無法滿足工業(yè)生產(chǎn)檢測的需要
-
需要大量化學(xué)試劑，污染環(huán)境，不環(huán)保
-
影響化驗人員的健康
