Yam ntxwv
2,4,6-Trimethylaniline yog ib qho nruab nrab siv dav hauv dyes, tshuaj tua kab thiab lwm yam lag luam.Cov khoom siv raw rau kev sib txuas ntawm mesitidine yog mesitylene, uas muaj nyob hauv roj av.Nrog rau kev ua tiav ntawm kev lag luam loj hauv Suav teb, cov khoom tsim tawm ntawm mesitylene tau nce ntxiv, yog li kev txhim kho ntawm nws cov khoom lag luam hauv qab tau txais ntau thiab ntau dua.Cov khoom qis qis ntawm mesitylene, xws li trimellitic acid, mesitidine, thiab M acid, yog txhua yam khoom siv tshuaj tseem ceeb.Mesitylene yog siv los ua raw khoom los ua ke mesitidine.Cov tshuaj tiv thaiv nitration ntawm mesitylene yog qhov tseem ceeb, uas ncaj qha ntsig txog cov nqi tsim khoom thiab cov khoom zoo.
Daim ntawv thov
Cov khoom ntshiab ntawm mesitidine yog cov kua tsis muaj xim thiab pob tshab thaum raug huab cua, thiab nws yooj yim hloov xim, thiab cov khoom feem ntau yog xim av.Insoluble hauv dej, soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether.Mesitylene yog ib qho nruab nrab ntawm dyes, organic pigments thiab tshuaj tua kab.Feem ntau yog siv nyob rau hauv lub synthesis ntawm dyes.Nws yog qhov nruab nrab ntawm qaug zog acid ci ntsa iab xiav RAW.Nws yog qhov nruab nrab ntawm qaug zog acid dye Praslin RAW.
Kev npaj
1) Nyob rau hauv 50 mL tas li lub siab poob qis, thawj zaug ntxiv 10 g ntawm acetic acid, thiab tom qab ntawd ntxiv 13.5 g ntawm 98% nitric acid, sawv ntsug thiab txias kom qis dua 25 ° C.Hauv 250 mL plaub-caj dab, ntxiv 24.5 g ntawm acetic anhydride thiab 24 g ntawm mesitylene nyob rau hauv ib theem, thiab ntxiv cov npaj nitric acid tov dropwise thaum stirring ntawm 20-25 ° C.Tom qab cov dej ntws tiav lawm, khaws cia ntawm 0 ~ 25 ℃ rau 2h hauv 2 Chemicalbook, ces tsa nws mus rau 35 ~ 40 ℃ thiab khaws cia rau 2h.Kev kuaj tau kuaj los ntawm cov kua chromatograph, thiab thaum kuaj tsis pom mesitylene, cov tshuaj tiv thaiv raug txiav.Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:
2) Kev kho cov tshuaj nitrification tom qab muaj ob txoj hauv kev tseem ceeb rau kev kho cov tshuaj nitrification tom qab, dej ntxuav thiab distillation.Kev ntxuav dej: Tom qab cov tshuaj tiv thaiv nitration dhau lawm, ntxiv txog 40g dej rau hauv lub khob, nce qhov kub ntawm 65 ℃, cais cov txheej thaum nws kub, ntxuav nrog 65 ℃ dej kub rau 2 mus rau 3 zaug, cov txheej txheem organic. yog nitro mesitylene.Txoj kev Distillation: Tom qab cov tshuaj tiv thaiv nitration dhau lawm, qhov kub tau nce mus rau 70-80 ° C, thiab tom qab ntawd cov acetic acid raug tshem tawm los ntawm lub tshuab nqus tsev distillation kom tau txais nitro mesitylene.
