Abstract：Thisstudyusedtheacetone solublecontent inpulpasanevaluationindexandoptimizedtheSoxtec methodusing Box-Behnken response surface methodology. The results showed that the optimal extraction parameters were temperature of 76°C ，time of 25 min，and solvent volume of 64 mL. Through experimental verification，the LOD of this method was 0.013% ，the spiked recovery rate was > 95 % ，the coefficientof variation of repeatabilitywas <5% ，and the coefficient of variation of reproducibilitywas <10% . The detection results met the requirementsoftheGB/7417—2017，indicatingthathismethodhadhighaccuracyandgodreproducibility，methequalitycotrolequirementsof industrialpulpproduction，andprovidedamoreficientandreliablesolutionforacetonesolublesubstancedetectio.
