1-Butanol → Butyl ethyl(2-hydroxyethyl)phosphinate
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1-Butanol | HCID 263 | — |
| Reactant | Water | HCID 962 | — |
| Reactant | HCID 46832563 | HCID 46832563 | — |
| Solvent | Toluene | HCID 1140 | — |
| Product | Butyl ethyl(2-hydroxyethyl)phosphinate | HCID 46832566 | 86% |
Reaction Steps
414 g (3 mol) of the ethyl(2-hydroxyethyl)phosphinic acid obtained (produced as in Example 8) are at 85° C. dissolved in 400 ml of toluene and admixed with 888 g (12 mol) of butanol. At a reaction temperature of about 100° C., the water formed is removed by azeotropic distillation to leave 500 g (86% of theory) of butyl ethyl(2-hydroxyethyl)phosphinate purified by distillation at reduced pressure.
