红外光谱是研究有机化合物的重要物理方法之一,在结构鉴定和定量分析方面得到广泛应用。在木素化学领域,红外光谱也有各种用途。国外对木素红外光谱的研究,始于50年代,最初大多研究各种分离木素的光谱学,即对红外光谱作出合理的定性解释,近年开始转入定量研究。 木素的结构和性质受材种、部位,树龄及地理,物候条件的影响颇大,同时,木素的不同分离方法也会对木素的性质产生不同程度的影响。因此,各国研究者的结果,往????????
Infrared spectroscopy is one of the most important physical methods to study organic compounds, and has been widely used in the field of structure identification and quantitative analysis. In the field of lignin chemistry, infrared spectroscopy also has a variety of uses. Foreign research on lignin infrared spectroscopy, began in the 1950s, most of the initial study of spectroscopy of lignin isolated, that is, a reasonable qualitative interpretation of infrared spectroscopy, quantitative analysis of the transfer into the study in recent years. The structure and properties of lignin are greatly affected by species, location, age, geography and phenology. At the same time, different isolation methods of lignin also affect the properties of lignin in varying degrees. Therefore, the results of researchers from various countries, to ????????
