Nā hiʻohiʻona
ʻO 2,4,6-Trimethylaniline kahi mea waena i hoʻohana nui ʻia i nā mea pena, nā pesticides a me nā ʻoihana ʻē aʻe.ʻO ka mea maka no ka synthesis o ka mesitidine he mesitylene, aia i loko o ka ʻaila.Me kaʻikeʻana i ka hanaʻoihanaʻoihana nui ma Kina, ua hoʻomauʻia ka hoʻonuiʻana o ka mesitylene, no laila ua loaʻa i ka hoʻomohalaʻana o kāna mau huahana i lalo.ʻO nā huahana lalo o ka mesitylene, e like me ka trimellitic acid, mesitidine, a me ka M acid, he mau huahana kemika koʻikoʻi.Hoʻohana ʻia ʻo Mesitylene ma ke ʻano he mea maka no ka synthesize mesitidine.ʻO ka hopena nitration o mesitylene ke kī, pili pono i ke kumukūʻai hana a me ka maikaʻi o ka huahana.

ʻO ka huahana maʻemaʻe o ka mesitidine he wai kala ʻole a ʻike ʻia ke ʻike ʻia i ka ea, a he maʻalahi ke hoʻololi i ke kala, a he ʻeleʻele māmā ka huahana.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera.ʻO ka Mesitylene kahi mea waena o nā kala, nā puaʻa organik a me nā pesticides.Hoʻohana nui ʻia i ka synthesis o nā dyes.ʻO ia ka waena o ka waika palupalu RAW uliuli.ʻO ia ka waena o ka waiʻona palupalu Praslin RAW.
Hoʻomākaukau
1) I loko o ka 50 mL ka hoʻoheheʻe ʻana o ke kaomi mau, hoʻohui mua i 10 g o ka acetic acid, a laila hoʻohui i 13.5 g o 98% nitric acid, kū a hoʻomaha a ma lalo o 25° C. no ka hoʻohana ʻana.I loko o ka pahu ʻāʻī ʻehā 250 mL, e hoʻohui i 24.5 g o ka acetic anhydride a me 24 g mesitylene ma ke kaʻina, a hoʻohui i ka wai nitric acid i hoʻomākaukau ʻia me ka hoʻoluliluli ʻana i ka 20-25°C.Ma hope o ka pau ʻana o ka kulu ʻana, e mālama iā ia ma 0~25 ℃ no 2h ma 2Chemicalbook, a laila e hoʻokiʻekiʻe i 35~40℃ a mālama iā ia no 2h.Ua hoʻāʻo ʻia ka laʻana e ka chromatograph wai, a ke ʻike ʻole ʻia ka mesitylene, ua hoʻopau ʻia ka hopena.Penei ka hoohalike pane.
2) Ma hope o ka mālama ʻana i ka hopena nitrification ʻElua mau ala nui no ka mālama ʻana i ka hopena nitrification, ka holoi wai a me ka distillation.ʻO ke ala holoi wai: Ma hope o ka pau ʻana o ka hopena nitration, e hoʻohui i kahi 40g o ka wai i ka ipu, e hoʻonui i ka mahana i 65 ℃, e hoʻokaʻawale i nā papa i ka wā wela, e holoi me 65 ℃ wai wela no 2 a 3 mau manawa, ka pae organik ʻO ka nitro mesitylene.ʻO ke ʻano distillation: Ma hope o ka pau ʻana o ka hopena nitration, hoʻokiʻekiʻe ʻia ka mahana i 70-80 ° C, a laila hoʻoneʻe ʻia ka acetic acid e ka distillation vacuum e loaʻa ai ka nitro mesitylene.
