Although available literature does not unequivocally establish the presence of open ether bonds (R-O-R) in low-rank bituminous coals, formation of low-molecular-weight products on reacting such coals with hydrogen donors is usually interpreted in terms of scission of ether bridges. This lack of cons

The constants of thermolysis rate of C,H,~(CH,),~O~(CH,),-C6HS ethers were measured in conditions close to those of coal liquefaction (hydrogen pressure of 8.5 MPa; temperature up to 410Β°C) but minimizing secondary conversions (i.e. in ten-fold excess of tetralin). The ethers form the following reac
