Dear Botros;

this is the ASTM standard method.

ASTM E222 - 10

Standard Test Methods for Hydroxyl Groups Using Acetic Anhydride Acetylation.

Regards

Navneet Kumar

Dear Botros,

Determine hydroxyl value by 859 Trioterm is not possible, But possible by other instrument of Titrando - Metrohm; As followed by ASTM E 1899-08.

Other methods are available ASTM D 4274-99 or ISO : 4629.

Regards,

Botros S Meglaa

many thanks dears Abdelkader BOUAZIZ and Navneet Kumar
