Abstract
Abstract Octadecanoic acid was investigated as a model compound for one of the functional groups known to occur in low-rank coals, viz. carboxylate groups. TG, DTG, TG—MS and high pressure DTA were used to elucidate the type of reactions occurring during pyrolysis and hydropyrolysis of octadecanoate salts. The decomposition temperature varied from about 300°C for the tin(II) salt to 500°C for the potassium salt, apparently because of the varying ionic bond strengths involved. Only those salts which decomposed to form metal oxides gave significant amounts of carbon dioxide during the organic decomposition reaction; the others gave mainly carbon monoxide.
