Abstract

Proces obuhvata obezbeđenje rastvora formaldehida koncentracije u opsegu od 80-89 %, zagrevanje rastvora do temperature od 80В°C do 100В°C, sipanje zagrejanog rastvora na metalnu transportersku traku koja se kreće iz prvih, zagrejanih zona ka drugim, rashladjenim zonama. Poželjno je da se rastvor formaldehida prethodno pomeša sa nekim katalizatorom.
