X-ray, microscopic, and thermogravimetric analyses were used to study the interaction of Bi2-xSr2Ca2Cu3O10+y, Ca2CuO3, Sr2CuO3, CaSrCuO3, SrCuO2, BaCuO2, and Li2CuO2 powders with ethylene glycol at room temperature. It was determined that glycolic alcoholates are obtained as a result of interaction of simple cuprates and ethylene glycol. The compounds M(2)[Cu(CH2OCH2OH)(6)] (M = Ca, Sr), M[Cu(CH2OCH2O)(2)] (M = Sr, Ba), Li-2[Cu(CH2OCH2OH)(4)], and Li-2[Cu(CH2OCH2O)(2)(H2O)(2)] have been isolated and identified. Chemical transformation of Bi2-xSr2Ca2Cu3O10+y leads to the formation of glycolic alcoholates mixture with the compositions Sr[Cu(CH2OCH2O)(2)], Ca-2[Cu(CH2OCH2OH)(6)], CaSr[Cu(CH2OCH2OH)(6)], and the unidentified amorphous phases containing bismuth and lead.
