Popis: | Normal aliphatic carboxylic acids and ketones obtained from the extraction of Taimylyr (Lensky basin, USSR) or Matagan (Irkutsky basin, USSR) sapropelitic coal with water and sodium hydroxide at elevated pressure and temperatures from 400 to 450 °C were investigated. The compositions of these compounds were studied by i.r. and n.m.r. spectroscopy, and combined g.c.-m.s.. The possible pathways of aliphatic carboxylic acids and ketones formation during the fossilization process are discussed. |
