Reference of 3-Methyl-1H-pyrrole. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3-Methyl-1H-pyrrole, is researched, Molecular C5H7N, CAS is 616-43-3, about Structure of “”unknown”” soil nitrogen investigated by analytical pyrolysis.
Curie-point pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS) and in-source pyrolysis-field ionization mass spectrometry (Py-FIMS) were applied for the 1st time to the structural characterization of organic N in hydrolyzates and hydrolysis residues resulting from the classical 6 M HCl hydrolysis of mineral soils. Two soils of widely different origin (i.e., a Gleysol Ah and a Podzol Bh) were investigated. Py-GC/MS was performed using a N-selective detector to detect and identify N-containing pyrolysis products in the hydrolyzate (e.g., pyrazole and/or imidazole, N,N-dimethylmethanamine, benzenacetonitrile, propane- and propenenitriles) and the hydrolysis residue (e.g., pyrroles, pyridines, indoles, N-derivatives of benzene, benzothiazole, and long-chain aliphatic nitriles). Temperature-resolved Py-FIMS allowed the thermal evolution of the N-containing compounds to be recorded during pyrolysis. These were characterized by a particularly high thermostability compared to their thermal release from whole soils. The combination of pyrolysis with mass spectrometric methods permitted analyses of the identities and thermal stabilities of complex N compounds in hydrolysis residues of whole soils, which cannot be done by wet-chem. methods. Pyrolysis-methylation GC/MS with NMe4OH enabled the identification of N,N-dimethylbenzenamine and so confirmed the identification of benzeneamine by Py-GC/MS in nonmethylated hydrolysis residues. N-derivatives of benzene and long-chain nitriles are characteristic of soils, terrestrial humic substances, and hydrolysis residues and seem to be specific, stable transformation products of soil N.
