Reaction Steps
500 ml (565 g, 6.56 mol) of gamma-butyrolactone are placed in 2.0 l of methanol. 1.28 kg (6.56 mol) of methylglucamine are added to the solution obtained. The mixture is then refluxed for 16 hours. The solution obtained is evaporated to dryness. The colourless syrup so initially obtained crystallises into a white solid after a few days at room temperature. (Melting point 78°-79° C.)
