• Mathematical analyses of noncatalytic coal dissolution using tetralin at 350–460 °C were carried out. Coal conversion, SRC yield and aromaticity of SRC could be predicted fairly well by regression equations using liquefaction conditions as explanation variables. The equation derived from coal conversions in 67 experiments using the C% and volatile matter of 6 coals and liquefaction conditions could predict coal conversions fairly well (<I>R</I>=0.972). The conversions predicted by the proposed equation were also compared with those reported by previous investigators. Although it was suggested that long heating-up period was detrimental to coal conversion, the equation was a good indication of the conversion in solvent extract liquefaction.
