Product Information

• Name: 2,3,6-Tri-O-carboxymethyl-D-glucose
• Brand: Biosynth
• Description: 2,3,6-Tri-O-carboxymethyl-D-glucose (TCMG) is a potent polyelectrolyte that can be used as an additive to cellulose. TCMG is synthesized by the reaction of 2,3,6-tri-O-carboxymethylcellulose with potassium bitartrate in acidic medium. TCMG has been shown to interact with cellulose and form a gel matrix. This reaction is due to the ionic interactions between the carboxyl groups in TCMG and the hydroxyl groups in cellulose. The conductimetric titration measurement shows that TCMGs have a constant value at pH 5.5, indicating that they are anionic polyelectrolytes. Potentiometric titration indicates that TCMGs are nonionic polyelectrolytes and the interaction between these two polymers is due to electrostatic forces.
