54.Loy Yang炭の超臨界メタノール分解に及ぼす混合溶媒効果

抄録

Supercritical methanolysis of Loy Yang coal was examined by adding different alcohols, such as ethanol, n-propanol and i-propanol. Addition of these alcohols to methanol increased the conversion from 58% to 90% at maximum and brought about the increase in the fractions of phenol and cresols at the expenses of trimethyl- and tetramethyl phenols, which were the main products when the coal was reacted in a supercritcal methanol. Detailed experiments by changing the mixing ratio of i-propanol and methanol revealed a possibility to control the methylation distribution of phenols.
