Yield:-
Reaction Conditions:
with potassium hydroxide at 110; under 1875.19 Torr; for 2 h;Inert atmosphere;Autoclave;Large scale;
Steps:
3.1
Step one, the 284.48kg (1000mol) stearic acidInto the polymerization vessel inside, 1.2kg of potassium hydroxide was added with stirring, and then introduced into the polymerization reactor in a nitrogen atmosphere in the autoclave conversion, when the polymerization vessel with nitrogen positive pressure with nitrogen feed tank to 88.1kg (2000mol) Epoxy ethane promote polymerization vessel, while stirring the temperature was raised to 110 deg.] C, the pressure was adjusted to 0.25MPa, the polymerization reaction for 2 hours, with nitrogen and polymerization of the polymer in the autoclave was extruded, that is stearic acid polyoxyethylene (2) ether.
