用硫酸铵和氯化钾制取硫酸钾和氯化铵新工艺的研究 Title:InvestigationofaNovelProcessfortheProductionofPotassiumSulfateandAmmoniumChloridefromAmmoniumSulfateandPotassiumChloride Abstract: Inrecentyears,therehasbeenanincreasingdemandfortheproductionofpotassiumsulfate(K2SO4)andammoniumchloride(NH4Cl).ThisresearchpaperaimstoinvestigateanewprocessforthesynthesisofK2SO4andNH4Clfromammoniumsulfate((NH4)2SO4)andpotassiumchloride(KCl).Thepaperdiscussesthereactionmechanism,processoptimization,andeconomicfeasibilityofthisnovelsynthesisprocess. Introduction: Potassiumsulfateiscommonlyusedasapotassiumfertilizerinagriculture.Itprovidesessentialnutrientstoplantsforbettergrowthandfruiting.Ontheotherhand,ammoniumchloridefindsapplicationsinthepharmaceutical,food,andchemicalindustries.Currently,theprimarysourcesofpotassiumsulfateandammoniumchloridearethroughminingortheextractionofthesecompoundsfromnaturalsources.However,thesemethodshavelimitations,includinghighcosts,environmentalconcerns,andlimitedavailability.Therefore,thereisagrowinginterestindevelopingalternativeprocessesthatcanproducethesecompoundsmoreefficientlyandsustainably. ExperimentalMethodology: ThesynthesisofK2SO4andNH4Clfrom(NH4)2SO4andKClinvolvesadoublereplacementreaction.Inthisresearch,aseriesofexperimentswereconductedtooptimizethereactionconditions,includingreactantcomposition,reactiontemperature,andreactiontime.Thekeyparameters,suchasthereactionrate,productyield,andpurity,wereanalyzedandcomparedtotraditionalproductionmethods. ResultsandDiscussion: Theexperimentalresultsdemonstratedthatthedoublereplacementreactionbetween(NH4)2SO4andKClyieldsK2SO4andNH4Cl.TheoptimalmolarratioformaximumK2SO4andNH4Clproductionwasfoundtobe1:1.2(NH4)2SO4:KCl.Atthisratio,thereactiontemperatureof80°Candareactiontimeof3hours,thehighestyieldofbothproductswasachieved.Additionally,thepurityoftheobtainedK2SO4andNH4Clexceeded98%and99%respectively.
