ASTM E222-23 《Standard Test Methods for Hydroxyl Groups Using Acetic Anhydride Acetylation》 Related products

This standard describes test methods for the determination of hydroxyl groups in compounds using acetylation of acetic anhydride, including primary and secondary hydroxyl groups. Test methods include pressure flask method, reflux method and perchloric acid catalysis method, each method is suitable for different hydroxyl content ranges and reaction conditions. The standard provides precise test procedures to ensure the accuracy of determination results and requires reference to safety table data (SDS) for relevant safety information before use.
