TRIMETHYOLPROPANE CONTINUOUS SYNTHESIS METHOD

TRIMETHYOLPROPANE CONTINUOUS SYNTHESIS METHOD

Inventia de fata se refera la un procedeu de sinteza a trimetilolpropanului, ce consta în aceea ca, într-o prima faza, se efectueaza preamestecarea solutiei de CH2O cu NaOH, la o temperatura de 30...35 degree C si un timp de stationare de 5...25 min, lucrând cu solutii de formaldehida de concentrati...

description Inventia de fata se refera la un procedeu de sinteza a trimetilolpropanului, ce consta în aceea ca, într-o prima faza, se efectueaza preamestecarea solutiei de CH2O cu NaOH, la o temperatura de 30...35 degree C si un timp de stationare de 5...25 min, lucrând cu solutii de formaldehida de concentratii 10...20%, pentru a asigura nivelul optim de dilutie, urmeaza dozarea aldehidei n-butirice si apoi perfectarea reactiei în intervalul 30...60 degree C.
