Tripentaerythritol is slightly soluble in water but insoluble in ethanol and acetone etc. TRI-PE is a by-product of pentaerythritol production. Tripentaerythritol can be got under the condition of acid and alkaline formaldehyde, acetaldehyde via aldol condensation reaction.Tripentaerythritol is a white, odorless and crystalline powder.
The sucking filter of the present invention consists of end plate, tube plate, small tube plate, filtering tube and tubelet. Compared with available technology, the present invention has the advantages of high separation effect, low ash content in tripentaerythritol, high quality of monopentaerythritol and dipentaerythritol products. Moving the sucking filter to unloading tank, cutting off vacuum and blowback to unload tripentaerythritol and final drying.
