Determination of the chlorinating reaction products of [2,2]-Paracyclophane by GC-MS

Gas chromatography with ion-trap mass spectrometric detector(GC-MS)was used to determine the chlorinating reaction products of [2,2]-paracyclophane(PCP).Results with mass chromatogram analysis indicates the chlorinating reaction products of PCP are chloro-[2,2]-paracyclophane mixtures,and different compound has a few kinds of isomers respectively.Chloro-[2,2]-paracyclophane mixture consists of one-chloro-[2,2]-paracyclophane(one-chloro-PCP)with single structure,two-chloro-[2,2]-paracyclophane(two-chloro-PCP)with five types of isomers,and three-chloro-[2,2]-paracyclophane(three-chloro-PCP)with four types of isomers.In fact,there are three isomers with two Cl on two benzenes respectively and two isomers with two Cl on a benzene simultaneity in two-chloro-PCP compound,there are four isomers with a Cl on a benzene and two Cl on the other benzene in three-chloro-PCP compound.The two-chloro-PCP compound is determined to be the main component and the others are subsidiary substances from RIC of the chlorinating products of PCP.

Gas chromatography with ion-trap mass spectrometric detector（GC-MS） was used to determine the chlorinating reaction products of [ 2,2 ]-paracyclophane（PCP）. Results with mass chromatogram analysis indicates the chlorinating reaction products of PCP are chow-[ 2,2 ]-paracyclophane mixtures, and different compound has a few kinds of isomers respectively . Chlow-[ 2,2 ]- paracyclophane mixture consists of one-chloro- [ 2,2 ] -paracyclophane （one-chloro-PCP） with single structure, two-chloral[ 2,2 ] - paracyclophane （two-chlom-PCP） with five types of isomers, and three-chloro- [ 2,2 ] -paracyclophane （three-chloro-PCP） with four types of isomers. In fact ,there are three isomers with two CI on two benzenes respectively and two isomers with two CI on a benzene simultaneity in two-chloro-PCP compound,there are four isomers with a C1 on a benzene and two （3 on the other benzene in three- chloro-PCP compound. The two-chloro-PCP compound is determined to be the main component and the others are subsidiary substances from RIC of the chlorinating products of PCP.
