Production Method

It is obtained by condensing glucose with monomethylamine and then performing catalytic hydrogenation. The anhydrous ethanol and the dried glucose were added to the reaction pot, and the dried monomethylamine gas was passed at 50 ° C. After 1.5-2 h, the solution was gradually clarified and kept at 50 ° C for 2 h to obtain a glucose methylamine solution. Then, it was added to the autoclave, and in the presence of Raney nickel, hydrogen was pressurized to 2.5 MPa, and stirred at 80-85 ° C for 1-2 h. Then, after cooling and pressure-relieving, the upper layer of meglumine ethanol solution is cooled and crystallized, and filtered to obtain crude meglumine, which is then refined to obtain a finished product.

Meglumine Usage

1. Meglumine can be used as a contrast agent and surfactant for medical use.

2. Meglumine is an amino sugar derived from sorbitol and contains an amino group, a primary hydroxyl group and a secondary hydroxyl group, which can activate nucleophilic and electrophilic structures in chemical reactions through hydrogen bonding and provided lone pair electrons, respectively. reaction. Therefore, it can not only activate the reaction components through the alkali center, but also utilize hydrogen bonding to achieve the purpose. Due to its extraordinary properties, such as low toxicity, biodegradability, physiological inertness, reusability, non-corrosiveness, and low cost, meglumine has become an important and efficient catalyst in organic synthesis, which has inspired The more researchers are interested in it.
