A method for controlling plasticizer conversion using near infrared analysis
Monitoring an acid or anhydride and alcohol esterification reaction mixture by means of near infrared analysis such that the conversions and/or concentrations of water, acids, alcohols, and/or ether by-products, and/or other compositional properties of the reaction mixture in the presence of excess...

| Zusammenfassung: | Monitoring an acid or anhydride and alcohol esterification reaction mixture by means of near infrared analysis such that the conversions and/or concentrations of water, acids, alcohols, and/or ether by-products, and/or other compositional properties of the reaction mixture in the presence of excess alcohol and carboxylic acid can be predicted, thereby allowing for real-time control of the overall esterification process. |
