摘要
以N,N-二环己基碳二亚胺(DCC)为缩水剂,合成了目标化合物1,2-O-异丙叉基-3,5-O-二肉桂酰基-α-D-呋喃木糖,其结构经红外光谱(IR)、核磁氢谱(1H NMR)、核磁碳谱(13C NMR)和质谱(MS)等方法得到了确证;对其300、600、900℃的热裂解成分进行GC/MS分析,并对该目标化合物进行卷烟加香试验,结果表明,该化合物热裂解可得到51种有香味的醛、酮、酸、酯类化合物;该化合物添加量为0.01%时,可以改善卷烟香气质,增加香气量,降低刺激性,改善余味。
The target compound 3,5-O-dicinnamic acid-1,2-O-isopropylidene——D-xylofuranose was synthesized using DCC as dehydration reagent,the structure of which was confirmed by IR,1H NMR,13C NMR and MS spectra.This precursor was pyrolysised at 300,600 and 900 ℃ and applied in cigarette flavoring.The results showed that there were 51 kinds of aromatic aldehydes,ketones,acids,esters in the pyrolysis products of the target compound.At concentration of 0.01%,this compound could enhance the aroma quality and the volume of smoke,reduce irritancy and improve the aftertaste.
