Stage #1: at 20℃; for 0.50 h; Large scale
Stage #2: at 0 - 3℃; for 3.50 h; Large scale
To a reaction vessel, 10.326kg (166.3mol) of ethylene glycol was added with 3.66 Kg (83.185mol) of freshly distilled acetaldehyde and stirred slowly at room temperature for 30 mins. 14.622 Kg (91.504 mol) of bromine was added dropwise, after the dropwise addition, the reaction was carried out at 0-3°C for 3.5h, and the fraction was distilled under reduced pressure. The fractions (3.6 kPa) and 11.002 Kg (65.883 mol) of 80-82 ° C were collected and identified as bromoacetaldehyde ethylene glycol, the yield is 79.2percent, the content is more than 95percent.
