Abstract：

Trans-stilbene　(TSB)　solutions　were　treated　via　reflux　heating　with　cyclohexanone　as　a　solvent.　The　effect　of　reflux　heating　time　on　the　saturation　temperature　of　the　solution　was　investigated,　and　the　compositions　of　the　heated　solutions　were　analyzed　by　high-performance　liquid　chromatography　(HPLC)　and　gas　chromatography-mass　spectrometry　(GC-MS).　The　crystals　were　grown　in　the　solutions　by　a　slow-cooling　method.　The　results　show　that　cyclohexanone　is　an　effective　solvent　for　the　growth　of　TSB　crystals,　and　the　proper　heat　treatment　of　reflux　to　the　solution　can　accelerate　the　equilibrium　of　solvating　reaction　and　improve　the　stability　of　the　solution　in　a　certain　degree.　Also,　the　perfection　and　scintillation　property　of　the　crystals　improve　although　a　small　amount　of　impurities　appear　in　the　reflux　period.　©　2019,　Editorial　Department　of　Journal　of　the　Chinese　Ceramic　Society.　All　right　reserved.
