Intshayelelo
I-4-Nitro-3,5-dimethylbenzoic acid i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- 4-Nitro-3,5-dimethylbenzoic acid yikristale engenambala eqinileyo kunye nencasa enuka kamnandi.
- Izinzile kwiqondo lobushushu begumbi, kodwa ugqabhuko-dubulo lunokuthi lwenzeke kumaqondo obushushu aphezulu, ekukhanyeni, okanye xa luvezwe kwimithombo yomlilo.
- Iphantse yanganyibiliki emanzini, kodwa inyibilika kwizinyibilikisi zendalo ezifana ne-ethanol, ii-ethers, kunye neehydrocarbon ezikloriniwe.
Sebenzisa:
- I-4-nitro-3,5-dimethylbenzoic acid isetyenziswa kakhulu njenge-intermediate yedayi kunye ne-raw material for synthesis of pigments.
Indlela:
- I-4-Nitro-3,5-dimethylbenzoic acid inokufumaneka nge-nitrification ye-p-toluene. Iimpendulo ze-nitrification ngokuqhelekileyo zisebenzisa umxube we-nitric acid kunye ne-asidi ye-sulfuric njenge-agent ye-nitrifying.
- Indlela ethile yokulungiselela ngokuqhelekileyo: i-toluene ixutywe ne-nitric acid kunye ne-asidi ye-sulfuric, ishushu ekuphenduleni, kwaye emva koko i-crystallized kwaye ihlanjululwe.
Ulwazi ngoKhuseleko:
- I-4-Nitro-3,5-dimethylbenzoic acid iyacaphukisa kwaye iyingozi kwaye kufuneka igwenywe ngokudibana nolusu kunye namehlo.
- Xa uphethe le khompawundi, nxiba iiglavu zokukhusela, iziphefumli, kunye neeglasi ezikhuselayo ukuphepha ukuphefumla iigesi okanye ukudibana nolusu.
- Xa ugcina kwaye uphatha, kunqande ukudibana ne-oxidants, imithombo yokutshisa kunye nezinto ezinokutsha ukuphepha umlilo okanye ukuqhuma.
- Kwimeko yokungenwa ngengozi okanye ukuphefumla, funa unyango ngokukhawuleza kwaye ubonise iphepha ledatha yokhuseleko lwemveliso kugqirha wakho.
