further drying leads to intercalation compound 'coal-MOH' formation. This work has demonstrated that reorganization of over-molecular structure for all investigated coals is found. Emphasis is put on brown coal (Cd"' 73.6%) and anthracite (Cd"' 95.2%) as extreme representatives of rank coals. 98100

The products of reduction and reductive alkylation of five demineralized coals run in a system of potassium/ liquid ammonia were subject to extraction by methylene chloride and n-pentane. The paper reports infrared and nuclear magnetic resonance (n.m.r.) characteristics of the extracts and the resul
