波谱

Dodecanol abietate succinic anhydride was synthesized from abietic acid.The structures of products were characterized by spectrum of IR，HNMR and MS.

以枞为起点，合了十二醇酯酐，采用红外光谱、核磁共振波谱及质谱对中间产物及终产物进行了结构表证。

The metol content and the hydroquinol content in developer solution were analyzed by potential spectrum method.During this analysis, two components were continuously titrated at the same time.

采用一种新化析方法电位波谱法析显影液中米吐尔和对苯二酚含量,在研究过程中实现了这两种连续滴定析。
