Total fragment sum relative to methanol (FSRM) of the different groups of volatiles from this work.
Functionality | Total FSRM (%) |
---|---|
CmHnN | 235 |
CmHnNO | 152 |
Acyclic | 245 |
Cyclic | 142 |
– N-Heteroycles | 89 (O-functionalized: 36) |
– NO-Heteroycles | 41 |
– Carbocycles | 12 |
Amines | 39 (Methylamine: 17) |
Nitriles | 129 (Hydrogen cyanide: 81) |
Amides | 53 (Formamide: 12) |
Lactams | 20 |
Oxazoles & isoxazoles | 41 |
Others (a) | 105 |
Inorganic (b) | 301 |
Organic (c) | 292 |
Notes. (a)Others include the following less abundant functionalities: imines, isocyanides, isocyanates, and acetylated N-heterocycles. We also include all unfunctionalized N-heterocycles in this residual group, even though some would actually classify them as amines. (b)To obtain the total amount of inorganic N, we sum over the FSRM of HCN and HNCO (both from this evaluation) and add NH3 (FSRM = 172%), N2 (FSRM = 17%), and NO (FSRM = 17%). (c)To obtain the total FSRM of organic N, we deduce from the total CnHmN and CnHmNO FSRM (387%) the fraction assigned to HCN (FSRM = 81%) and HNCO (FSRM = 14%).
