气相色谱–质谱法(GC-MS)2-巯基苯并噻唑废树脂苯胺法Gas Chromatography-Mass Spectrometry (GC-MS) 2-Mercaptobenzothiazole Spent Resins Aniline Process

摘要:

采用气相色谱–质谱法(GC-MS)对工业苯胺法合成2-巯基苯并噻唑(促进剂M)的副产废树脂进行了定性、定量测定。废树脂经四氢呋喃溶解后,采用GC-MS法测定,样品中分离的各种成分用NIST08谱库进行对照检索,采用面积归一法,计算出各化合物成分的相对含量。共鉴定了废树脂中的7种有机化合物,其中2-巯基苯并噻唑(M)和苯并噻唑(BT)的相对含量最高,分别为29.2%、31.1%。苯胺含量为6.2%,2,6-二叔丁基-4-甲基苯酚含量为17.4%,苯并噻唑衍生物含量共为14.2%,所鉴定的7种有机化合物峰面积之和占到总峰面积的98.1%。

The relative content and constituents of spent resins from the aniline process adopted to the syn-thesis 2-mercaptobenzothiazole (the Accelerator M) were analyzed by gas chromatography-mass spectrometry (GC-MS). After being dissolved in tetrahydrofuran, spent resins were measured by GC-MS and identified by NIST08. The relative content of each component was determined by area normalization. Total 7 constituents were identified in spent resins, wherein the relative contents of 2-mercaptobenzothiazole (M) and benzothiazole (BT) were the highest, accounting for 29.2% and 31.1% respectively. The contents of aniline, 2,6-Di-tert-butyl-4-methylphenol and benzothiazole derivative were 6.2%, 17.4% and 14.2%, taking 98.1% of the total peak area.
