What is FTIR Method for Hydroxyl Value of Polyols about?

The document describes a novel single-sample method using mid-FTIR spectroscopy to determine the hydroxyl values (OHV) of lipid-based polyols, which enhances automation and reduces sample preparation time compared to traditional methods. This method involves measuring the absorption changes of p-toluenesulfonyl isocyanate (TSI) before and after reacting with hydroxyl groups, with moisture compensation included for accuracy. The new approach provides similar accuracy and reproducibility to existing split-sam
