Product Description

polyether polyol (polyether for short) is an organic polymer, which is prepared by addition polymerization reaction of starting agent (compound containing active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of catalyst. The largest yield of polyether is to use glycerol (glycerol) as the starter and epoxide (usually PO and EO are used together), by changing the feeding method of PO and EO (mixed addition or separate addition), addition ratio, The feeding sequence and other conditions produce various general polyether polyols.

Production method

Pretreatment of raw materials-usually, the starting agent and catalyst are premixed first to generate metal hydrocarbon oxide, which is dehydrated in vacuum and then added to the reaction kettle.

Ring Opening Polymerization reaction-this reaction is an exothermic reaction, and the reaction heat must be removed in time; In order to prevent oxidation reaction, dry nitrogen must be introduced before the reaction.

Post-treatment process-mainly includes neutralization, adsorption, dehydration, filtration, distillation and other units.
