Yield:2274-11-5 10 %Chromat. ，4074-88-8 9 %Chromat.
Reaction Conditions:
with tempol;10H-phenothiazine;[Zn4O(benzene-1,4-dicarboxylate)3] at 59; under 7500.75 Torr;
Steps:
4 EXAMPLE 4; Alkoxylation of Acrylic Acid with Ethylene Oxide
33.2 g acrylic acid (stabilized with 2,2', 6,6'-tetramethyl-4-hydroxypiperidine-N-oxide and phenothiazine) and 0.5 g catalyst of Example 1 were weighed into a 300 ml steering autoclave under nitrogen atmosphere. The autoclave was closed and pressurized with 10 bar nitrogen. Upon steering 20 g ethylene oxide were subsequently introduced via a screw press. After five hours at 50° C. the catalyst was filtered off and the raw product was analyzed by gas chromatography. Based on the area percentages the following composition of the solution (residual ethylene oxide not considered): [0128] Acrylic acid 76%, monoethylene glycol acrylate 10%, diethylene glycol acrylate 9%, other side products 5%.
