Phenolic resin base multi-branched high molecular weight nonionic surface active agents were synthesized to evaluate their effects on improving the fluidity of coal-water slurry (CWS). The following results were obtained:<BR>1) Surfactants prepared by addition reactions of ethylene oxide (EO) with phenol resin, parasecondarybutyl phenol resin, nonyl phenolic resin or dodecyl phenol rein improved the fluidity.<BR>2) Nonyl or dodecyl is preferable as a resin alkyl group, and the number of nuclei of either from 12 to 19 is adequate.<BR>3) The number of moles of added EO should be such that each side chain has a molecular weight of about 3, 000.<BR>4) The addition of an agent equal to 0.4% of the coal to meet the above conditions 2) and 3) results in a viscosity of Tatung coal CWS of 1, 200cp at a coal concentration of 70%.
