1,4-Phthalaldehyde
Faka u-6.0 g we-sodium sulfide, u-2.7 g wempushana yesibabule, u-5 g we-sodium hydroxide no-60 ml wamanzi eflaskini engu-250 ml enentamo emithathu ene-reflux condenser nomshini oshukumisayo, bese ukhuphula izinga lokushisa libe ku-80.℃ngaphansi kokunyakaza.Impushana yesulfure Ephuzi iyancibilika, bese isixazululo sibe bomvu.Ngemuva kwe-refluxing ihora elingu-1, isisombululo se-sodium polysulfide esimnyama esimnyama sitholakala.
