AI Technical Summary

Technical Problem

Existing methods for synthesizing amino acid esters using orthoesters require stoichiometric amounts, resulting in identical alkyl residues and lack biodegradability, which is a challenge for sustainable detergent and cleaning compositions.

Method used

A process using substoichiometric or catalytic amounts of orthoesters to produce amino acid esters and their salts, allowing for the use of different alcohols and minimizing the amount of orthoester, thereby enhancing biodegradability and reducing environmental impact.

Benefits of technology

The process achieves biodegradable amino acid esters with equivalent cleaning properties, reducing CO2 emissions and resource consumption, aligning with sustainability goals in detergent and cleaning industries.
