Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | (Z)-4-ethoxy-4-oxobut-2-enoate | HCID 86733784 | — |
| Product | Diethyl Maleate | HCID 5271566 | — |
Reaction Steps
The bottom product from flash distillation column 417 is taken in line 449 to a secondary esterification reactor 450. This is provided with a stirrer 451 and a sparger 452 which is connected to a line 453 through which ethanol vapour is supplied to reactor 450. Further reaction of monoethyl maleate and ethanol occurs in reactor 450, resulting in formation of additional diethyl maleate. A stream containing recycled ethanol is returned to reactor 450 in line 454.
