Characterisation of an algerian asphaltene by 1H and 13C CPMAS NMR, DEPT and ESI mass spectroscopy

Characterisation of an algerian asphaltene by 1H and 13C CPMAS NMR, DEPT and ESI mass spectroscopy

Quantitative liquid 1H and solid 13C CPMAS NMR spectroscopy were used in combination with qualitative DEPT (Distortionless Enhancement by Polarization Transfer) and liquid 13C NMR to investigate the molecular structural parameters of an Algerian asphaltenes. The molecular weight of the asphaltene io...
