Nga ahuatanga
Ko te 2,4,6-Trimethylaniline he takawaenga e whakamahia nuitia ana i roto i nga waikano, pesticides me etahi atu ahumahi.Ko te rauemi mata mo te whakahiato mesitidine he mesitylene, kei roto i te hinu.Na te whakatutukitanga o nga mahi ahumahi nui i Haina, kua piki haere tonu te whakaputanga o te mesitylene, na reira kua nui ake te aro o te whanaketanga o ana hua o raro.Ko nga hua o raro o te mesitylene, penei i te waikawa trimellitic, mesitidine, me te waikawa M, he hua matū nui katoa.Ka whakamahia te Mesitylene hei rauemi mata hei whakahiato i te mesitidine.Ko te tauhohenga nitration o te mesitylene te mea matua, e pa ana ki te utu whakaputa me te kounga o te hua.
Taupānga
Ko te hua parakore o te mesitidine he wai kore tae me te wai marama i te wa e pa ana ki te hau, he ngawari ki te huri i te tae, he maha nga wa he parauri marama te hua.Karekau ki te wai, ka whakarewahia i roto i nga whakarewa waro penei i te waihano me te etera.Ko te Mesitylene he takawaenga o nga waikano, nga poaka waro me nga pesticides.Ka whakamahia te nuinga ki te whakahiato waikano.Ko te takawaenga o te waikawa ngoikore RAW kikorangi kikorangi.Koia te takawaenga o te waikano waikawa ngoikore Praslin RAW.
Whakaritenga
1) I roto i te 50 mL te kohanga whakaheke pehanga tonu, me tapiri tuatahi te 10 g o te waikawa ahetiki, katahi ka tapirihia te 13.5 g o te 98% waikawa nitric, ka tu ka whakamatao ki raro iho i te 25° C. hei whakamahi.I roto i te 250 mL ipu kaki wha, whakauruhia te 24.5 g o te acetic anhydride me te 24 g o te mesitylene i roto i te raupapa, me te taapiri i te wairewa waikawa nitric kua rite ki te maturuturu ma te whakaoho i te 20-25°C.I muri i te otinga o te whakamahu, me pupuri ki te 0～25℃ mo te 2h i roto i te 2Chemicalbook, katahi ka hiki ki te 35～40℃ ka pupuri mo te 2h.I whakamatauria te whakatauira ma te chromatograph wai, a ka kore i kitea te mesitylene, ka mutu te tauhohenga.Ko te whārite tauhohenga e whai ake nei:
2) I muri i te maimoatanga o te tauhohenga nitrification E rua nga tikanga matua mo te maimoatanga o te tauhohenga nitrification, te horoi wai me te whakamarumaru.Tikanga horoi wai: I muri i te mutunga o te tauhohenga whakakawa, taapirihia te 40 karamu o te wai ki te ipu, whakaarahia te pāmahana ki te 65 ℃, wehehia nga papa i te wa e wera ana, horoi ki te 65 ℃ te wai wera mo te 2 ki te 3 wa, ko te wahanga waro. he nitro mesitylene.Te tikanga whakamarumaru: I muri i te mutunga o te tauhohenga o te whakamaarama, ka piki ake te pāmahana ki te 70-80°C, katahi ka tangohia te waikawa ahetiki na roto i te whakamarumaru korehau kia whiwhi ai i te nitro mesitylene.
