Yield:-

Reaction Conditions:

with sodium hydroxide at 90 - 100; for 24 h;Inert atmosphere;Temperature;

Steps:

3.1; 6.1; 9.1 Step1: Synthesis of fatty alcohol polyoxyethylene ether
500g HO(CH2CH2O)4H and 40g sodium hydroxide were added to a three-necked flask, and the temperature was raised to 90 ° C under nitrogen atmosphere. After all the sodium hydroxide was dissolved, 210 g of bromododecane was added dropwise, and the temperature of the system was maintained at 90 ° C for 24 h. . After cooling, it was diluted with distilled water, and the organic phase was extracted by adding 400 ml of diethyl ether, dried by adding calcium chloride for 12 hours, and distilled under reduced pressure at 160 ° C and 340 Pa to obtain a homogeneous fatty alcohol polyoxyethylene ether.
