Study on Synthesis and Separation Process of Tri-pentaerythritol.

The effect of various operating factor on the tri-pentaerythritol yield,pentaerythritol total yield and the size of tri-pentaerythritol crystals were investigated. The optimal result indicated total yield≥95%, tri-pentaerythritol yield≥8%. The diameter of tri-pentaerythritol particles can be enlarged from 10～15μm to 60～70μm.
