groups of bis(2-hydroxyethyl) ether (compound 1) and tetraethylene glycol (compound 2) were modified by ethyl oxalyl chloride to produce two new compounds: oxalic acid 2-(2-ethoxy-oxalyloxy-ethoxy)-ethyl esterethylester (compound 3) and oxalic acid 2-2-[2-(2-ethoxyoxalyloxyethoxy)-ethoxy]-ethoxy}-ethyl esterethylester (compound 4). Then, the solubility of compounds 1 to 4 were investigated and compared
