丁醛是重要的有機化工產(chǎn)品,主要用于制造樹脂、增塑剎、硫化促進劑等。丁醛中主要雜質(zhì)有水、巴豆醛、丁酸及微量的乙醛、乙醇、丙酮等。丁醛含量為95％以上,用化學(xué)分析難度較大,準確度也差。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司采用氣相色譜儀(FID檢測器),聚乙二醇毛細管柱，對雜質(zhì)進行色譜定量后,用差減法計算丁醛含量,獲得了較為滿意的結(jié)果,最大相對偏差為5.26％。

本標準規(guī)定了工業(yè)用正丁醛的要求、試驗方法、檢驗規(guī)則、標志、包裝、運輸、貯存及安全。
本標準適用于由丙烯羰基合成法制得的工業(yè)用正丁醛

應(yīng)用：HG/T 4964-2016 工業(yè)正丁醛 

Butyraldehyde is an important organic chemical product mainly used in the manufacturing of resins, plasticizers, vulcanization accelerators, etc. The main impurities in butyraldehyde include water, crotonaldehyde, butyric acid, and trace amounts of acetaldehyde, ethanol, acetone, etc. The content of butyraldehyde is over 95%, which makes chemical analysis difficult and has poor accuracy.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a gas chromatograph (FID detector) and a polyethylene glycol capillary column to quantitatively analyze impurities. The butanal content was calculated using the subtraction method, and satisfactory results were obtained with a maximum relative deviation of 5.26%.

This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, and safety of n-butyraldehyde for industrial use.

This standard is applicable to industrial n-butanal obtained by propylene carbonyl synthesis method
