Study on chemical composition and formation mechanism of some typical pitch feedstocks using field desorption mass spectrometry
The molecular distributions and constitutions of several A-240 petroleum and coal tar pitch fractions were investigated using field desorption mass spectrometry. The molecular profiles of all samples analysed were greatly extended and the maximum mass weight of CTP-BSHI approached 640 corresponding...
