Study on Synthesis and Separation Process of Tri-pentaerythritol |
TENG Dong-cheng.(Hengyang sanhua enterprise Inc. Hunan Hengyang; 421002; China) |
Abstract: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. |
Key words:tri-pentaerythritol; synthesis; separation |
