The structures and compositions of castor oil and its ethoxylate derivative have been characterized by means of NMR and IR spectroscopy and MS spectrometry. The spectral band assignments are confirmed by Gradient Correlated Spectroscopy(gCOSY), Gradient ¹H-detected Heteronuclear Single-Quantum Coherence(gHSQC), Gradient ¹H-detected Heteronuclear Multiple-Bond Correlation(gHMBC) and Distortionless Enhancement by Polarization Transfer(DEPT) techniques. The results show that there are at least six series compounds in ethoxylate derivative of castor oil.
