| titleOfInvention | The preparation method of nonionic surfactant polyether polyol |
| abstract | The invention belongs to polyethers nonionogenic tenside technical field, be specifically related to a kind of preparation method of nonionic surfactant polyether polyol, concrete technology step is: alkylphenol 13.41-17.45%, initiator 0.93-3.58% and alkaline matter catalyzer 0.27-0.30%, at temperature 80 DEG C, stirring and dissolving is to homogeneous phase, nitrogen replacement, at temperature 90-110 DEG C, pass into propylene oxide (PO) 79.76-82.74% continuously, slaking 3 hours, in and Dehydration obtain polyether glycol; Above-mentioned percentage ratio is mass percent.The polyether glycol that preparation method of the present invention obtains, in washing composition, synthon and makeup, has good humidity-holding effect; All good to the stability of acid, alkali, salt, can be mixed with other ionic promoting agents.This preparation method is simple to operate, and side reaction is less. |
