Assessing and Grouping Chemicals Applying Partial Ordering Alkyl Anilines as an Illustrative Example

Area of Science:

• Chemistry
• Environmental Chemistry
• Mathematical Classification

Background:

• Chemical classification traditionally relies on cluster analysis methods.
• Partial ordering methodology offers an alternative approach to classification.

Purpose of the Study:

• To apply partial ordering methodology for classifying 21 alkyl substituted anilines.
• To compare the effectiveness of partial ordering with traditional cluster analysis methods.

Main Methods:

• Utilized partial order methodology and cluster analysis (K-means, hierarchical).
• Described chemical compounds using a multi-indicator system, including four environmental chemistry indicators.
• Constructed a Hasse diagram to represent the ordering of compounds.

Main Results:

• The Hasse diagram provided a more interpretable partitioning of the 21 alkyl anilines compared to K-means and hierarchical clustering.
• The partial ordering approach demonstrated utility in classifying chemical compounds.

Conclusions:

• Partial ordering methodology is a viable approach for chemical classification.
• Further theoretical development is needed to guarantee meaningful results in all cases.
