Wijs procedure

Iodine absorption was studied by Wolfrom and Husted23 with 2,3,4,6-tetra-0-methyl-(2-hydroxy-D-glucal). Analysis by the Wijs procedure showed utilization of 93 % of the amount required by one double bond. [Pg.108]

Unsaturation is described in Chapter 2, under characterization of nonionic surfactants. The Wijs procedure is most often specified for anionic surfactants. [Pg.19]

In this procedure, the polymer is reacted with an excess of standard iodine monochloride dissolved in glacial acetic acid ( Wijs reagent ) ... [Pg.88]

Procedure Determination of Iodine Number by the Wijs Method (74)... [Pg.78]

The usual procedure for determining unsaturation in quaternaries is the Wijs method, described in Chapter 2. The ASTM test optimized for determination of unsaturation of the alkyl group in fatty quaternary ammonium chlorides is D2078 (12). The corresponding AOCS method is Tg 3a-64 (11). For other compounds, the recommended AOCS method is Cd 1-25 (13). [Pg.112]

The usual procedure for determining unsaturation is the Wijs method, described in Chapter 2. The recommended ASTM and AOCS methods are D2075 and Cd 1-25, respectively (13,14). [Pg.123]
