Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Butyl bromide | HCID 8002 | — |
| Reactant | Diethylene Glycol Monobutyl Ether | HCID 8177 | — |
| Reactant | Sodium hydride | HCID 24758 | — |

Reaction Steps
Into 120 g of 60% NaH and 500 ml of toluene were added dropweise 329 g of butyl bromide and 486 g of diethylene glycol butyl ether at 50° C. Diethylene glycol dibutyl ether (abbreviated as “DEG-DB” hereafter) was obtained by distillation (b.p.: 256° C. under normal pressure) from the reaction mixture. The solubility of glycolide in this compound at 25° C. was 1.8%.
