红外线吸收光谱
The synthesis methods about the surfactant of different monoester of alcohol ether were introduced. The structure of product was confirmed by Infra-red absorption spectrum.
介绍了两种不同类型的醇醚单酯型表面活性剂的合成方法,并用IR对产品结构进行了认证。
The higher the absorbance ratio of Bronsted acid peak to Lewis acid peak ( i.e.AB/ AL) measured by infra-red absorption spectrum, the higher is the catalyst activity. The results show clearly that the Bronsted acid plays a dominant role in catalytic cracking reaction.
用红外光谱法测定了Bronsted酸峰与Lewis酸峰的吸光度(A)的比值,发现活性高的催化剂,其A B/A L值也高,说明在催化裂化反应中,Bronsted酸起主导作用。
