Abstract：Anetyfoalwaterurydispesant（TAS）wasstesidihtaicacid（T）atawmateraladbygaftopl zation of sodium ally-sulfonate and post-oxidation H2O2 .Through adjusting the reaction temperature，reaction time and the amount of sodium ally-sulfonate，the optimal reaction conditions were determined as follows：reaction temperature of 85°C and molar ratio of n（SAS） ： n（TA）= （204号 2：1 ，underwhichawellstabilizedoal-watersurryouldbeprepared.Thtructureofthedispersantascharacterzedbyifradspeto copy（IR）.Theviscosityandstabilityofthecoal-waterslurywereanalyzedyadingTAS.Atacoal-waterslurryconcentrationof 62% ，the optimal dispersant dosage was only 0.2% of the total dry coal mass，resulting ina favorable apparent viscosity （1020mPa⋅s andalowwater separation rate （ =3% after48h）．Allthecoal-waterslurryprepared exhibited excelent stabilityandflowability，indicating thatthistannic acid-based copolymer could be effectively applied as anadditive in coal-water slurry preparation.
