采用JMS—D300型气质联用仪,测定了南岔水解厂以针叶材为原料生产成品糠醛的化学组成。 分析过程分为两步;①用气相色谱仪分离出糠醛的各个组分;②用质谱仪对分离物鉴别定性(分离物的定性是与标准图谱对照进行的)。 色谱所分离的诸峰及其对应的各个化学组分如下:1号峰—丁二酮(C_4H_6O_286);2号峰—莰烯(C_(10)H_(16) 136);3号峰—萜二烯-(1,8)(C_(10)H_(16) 136);4号峰—α萜品烯(C_(10)H_(16) 136);5号峰—正己醇(C_6H_(14)O 102);6号峰—香芹酮(C_(10)H_(14)O 150);7号峰—糠醛(C_H_4O_2 96);8号峰—甲基糠醛(C_6H_6O_2 110);9号峰—未定;10号峰—邻甲氧基苯酚(C_7H_8O_2 124);11号峰—右旋葑醇(C_(10)H_(16)O 154);12号峰—莰醇-(2)(C_(10)H_(18)O 154);13号峰—蒈醇-(3)(C_(10)H_(18)O 154);14号峰—对-(?)烯酮(C_(10)H_(16)O 152)。
Using JMS-D300 GC-MS, the chemical composition of finished furfural produced by softwood needles was determined. The analysis process is divided into two steps; ① using gas chromatography to separate the various components of furfural; ② qualitative identification of isolates by mass spectrometry (isolates qualitative and control of the standard map). The peaks separated by chromatography and their respective chemical compositions are as follows: Peak 1 - Butanedione (C_4H_6O_286); Peak 2 - Camphene (C_ (10) H_ (16) 136) (C_ (10) H_ (16) 136); Peak 4α-terpinene (C_ (10) H_ (16) 136); Peak 5-n-hexanol (C_6H_ (C_ (10) H_ (14) O 150); Peak 7 - furfural (C_H_4O_2 96); Peak 8 - methylfurfural (C_6H_6O_2 110); Peak 9 - undetermined; peak 10 - o-methoxyphenol (C_7H_8O_2 124); peak 11 - dextrinol (C_ (10) H_ (16) O 154); peak 12 - (10) H 18 O 154); No. 13 peak-octanol- (3) (C_ (10) H_ (18) O 154) H_ (16) O 152).
