Hunhu
2,4,6-Trimethylaniline inzvimbo yepakati inoshandiswa zvakanyanya mudhayi, mishonga yezvipembenene uye mamwe maindasitiri.Iyo mbishi yekugadzirwa kwe mesitidine ndeye mesitylene, inowanikwa mu petroleum.Nekuitika kwehukuru hwekugadzirwa kwemaindasitiri muChina, kubuda kwe mesitylene kuri kuramba kuchiwedzera, saka kuvandudzwa kwezvigadzirwa zvayo zvepasi kwave kutariswa zvakanyanya.Zvigadzirwa zvepasi zve mesitylene, senge trimellitic acid, mesitidine, uye M acid, zvese zvakakosha zvigadzirwa zvemakemikari.Mesitylene inoshandiswa seyakabikwa kugadzira mesitidine.Iyo nitration reaction ye mesitylene ndiyo kiyi, iyo yakanangana nemutengo wekugadzira uye mhando yechigadzirwa.
Application
Iyo yakachena chigadzirwa che mesitidine haina ruvara uye yakajeka mvura kana ichinge yaiswa mumhepo, uye zviri nyore kuchinja ruvara, uye chigadzirwa chinowanzo tsvukuruka.Isinganyunguriki mumvura, inonyungudika muorganic solvents senge ethanol uye ether.Mesitylene inzvimbo yepakati yedhayi, organic pigments uye mishonga yezvipembenene.Inonyanya kushandiswa mukugadzirwa kwedhayi.Ndiyo yepakati isina simba asidhi inopenya bhuruu RAW.Ndiyo yepakati isina simba asidhi dhayi Praslin RAW.
Kugadzirira
1) Mu 50 mL inoramba ichimanikidza kudonhedza funnel, tanga wawedzera 10 g yeacetic acid, wobva wawedzera 13.5 g ye98% nitric acid, mira uye utonhore kusvika pasi pe25 ° C. kuti ushandise.Mune 250 mL ine mitsipa minana flask, wedzera 24.5 g yeacetic anhydride uye 24 g ye mesitylene munhevedzano, uye wedzera iyo yakagadzirwa nitric acid solution dropwise uchikurunga pa20-25°C.Mushure mekudonha kwapera, chengeta pa0～25℃ ye2h mu2Chemicalbook, wozoisimudza kusvika pa35～40℃ woichengeta kwe2h.Sampling yakaedzwa ne-liquid chromatograph, uye kana mesitylene isina kuwanikwa, kuita kwakamiswa.Iyo reaction equation ndeiyi inotevera:
2) Mushure mekurapa kwekuita nitrification Pane nzira mbiri huru dzepashure-kurapwa kwekuita nitrification, kugeza mvura uye distillation.Mvura yekugezesa nzira: Mushure mekuita nitration kwapera, wedzera anenge 40g emvura muflask, simudza tembiricha kusvika 65 ℃, patsanura maseru achiri kupisa, geza nemvura inopisa 65 ℃ ka2 kusvika katatu, iyo organic phase. inonzi nitro mesitylene.Distillation nzira: Mushure mekuita nitration kwapera, tembiricha inosimudzwa kusvika 70-80 ° C, uyezve iyo acetic acid inobviswa ne vacuum distillation kuti iwane nitro mesitylene.
