bis(oxiran-2-ylmethyl) benzene-1,2-dicarboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 24.0 g of 7,7,8,9,9-pentamethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione, 12.0 g of bis(2,3-epoxypropyl)phthalate and 0.5 g of potassium hydroxide were reacted in 200 ml of N,N-dimethylformamide, following substantially the same procedure as in Example 1. The desired Compound No. 130 was obtained in the form of a white powder, having an Rf value of 0.47 on thin-layer chromatography on silica gel using a 8:1:1:1 by volume mixture of ethyl acetate, benzene, ethanol and triethylamine as developing solvent.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Diglycidyl isophthalate and diglycidyl orthophthalate were prepared by caustic treatment of the products from the catalytic reaction of the corresponding phthalic acid with an excess of epichlorohydrin. Diglycidyl terephthalate was prepared in toluene from terephthaloyl chloride, glycidol, and triethylamine.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 20.0 g of 4-hydroxy-2,2,6,6-tetramethylpiperidine and 13.9 g of bis(2,3-epoxypropyl)phthalate was reacted following the procedure described in Example 5, to give the desired Compound No. 87 in the form of a white powder. The Compound had an Rf value of 0.24 on thin-layer chromatography on silica gel developed with a 20:4:2:1 by volume mixture of ethyl acetate, benzene, ethanol and triethylamine. was reacted
