2-Ethylhexyl glycidyl ether synthesis

3synthesis methods
2-Ethylhexyl glycidyl ether is made by condensation of 2-ethylhexanol with epichlorohydrin followed by dehydrochlorination with caustic to form the epoxy ring.

Yield:-

Reaction Conditions:

Stage #1: 2-Ethylhexyl alcoholwith tetrabutylammomium bromide;sodium hydroxide at -40; for 0.5 h;Inert atmosphere;
Stage #2: epichlorohydrin at 40; for 12 h;Reagent/catalyst;Temperature;

Steps:

1 Optimization of production process of 2-ethylhexyl glycidyl ether

1 mol of 2-ethylhexanol, 2 mol of NaOH and 0.005 mol of tetra-n-butyl ammoniumbromide (TBAB) were charged and stirred for 30 minutes at 40 ° C under a nitrogen atmosphere. Then, 2 mol of epichlorohydrin (ECH) was added dropwise at 40 ° C for 30 minutes using a metering pump, and reacted at different reaction temperatures for 12 hours. The reaction was then analyzed by GC to compare the reactivity with the reaction temperature. The experimental conditions and experimental results are shown in Table 1 below.
