Abstract

 

Due to the toxicity of aniline, it is desirable to find a replacement for aniline in the aniline point method. Here correlations between the aniline point and the turbidity temperature for 1,2-dimethoxybenzene, o-anisaldehyde, and p-anisaldehyde are presented. 1,2-Dimethoxybenzene correlates well to the aniline point but with a significantly lower turbidity point compared to the aniline point. p-Anisaldehyde also correlates well to the aniline point, and both the aniline point and the turbidity temperature are very similar in magnitude, making it a very strong candidate for replacement of aniline in the aniline point analysis.
