Dipentaerythritol is an organic compound with the formula O[CH2C(CH2OH)3]2. The molecular structure can be described as the ether derivative of pentaerythritol. It is therefore a polyol, which are useful in the production of alkyd resins. The compound is a by product in the production of pentaerythritol but also can be prepared intentionally from the latter:
- 2 C(CH2OH)4 → O[CH2C(CH2OH)3]2 + H2O
Several thousand tons are produced annually.
Further condensations are possible, yielding tripentaerythritol, etc.
Safety
The LD50 is greater than 2000 mg/kg (rat, oral).
