Pentaerythritol → Pentaerythritol Tetrakis(2,4-dimethoxybenzoate)
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Pentaerythritol | HCID 8285 | — |
| Reactant | 2,4-Dimethoxybenzoyl chloride | HCID 2734719 | — |
| Product | Pentaerythritol Tetrakis(2,4-dimethoxybenzoate) | HCID 20530744 | 78% |
Reaction Steps
Using the procedure of Eample I, 2,4-dimethoxybenzoyl chloride was allowed to react with pentaerythritol in the molar ratio of 4:1. The reaction gave a 78% yield of white crystalline product having a melting point of 125°-126.5° C. and the infrared spectrum was a consistent with the expected tetraester with no hydroxyl band and an ester carbonyl band at 5.85μ (s).
