Okwu mmalite
4-Methyl-2-nitrophenol bụ ngwakọta organic na usoro kemịkalụ C7H7NO3. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
4-methyl -2-nitrophenol bụ kristal siri ike, na-acha ọcha na-acha odo odo, ọ nwere isi ísì pụrụ iche na okpomọkụ. Ọ fọrọ nke nta ka ọ ghara ịsacha ya na mmiri, ma soluble na organic solvents dị ka ethanol na ether.
Jiri:
A na-eji 4-methyl-2-nitrophenol eme ihe na njikọ organic. N'ihi na ọ nwere ihe abụọ na-arụ ọrụ, hydroxyl na nitro, enwere ike iji ya dị ka onye na-ahụ maka nje bacteria, ihe nchekwa na peroxide stabilizer. Tụkwasị na nke ahụ, a na-ejikwa ya na-emepụta ihe eji esiji ákwà, pigments na fluorescent dyes.
Ụzọ nkwadebe:
4-methyl -2-nitrophenol nwere ike ịmepụta site na nitration nke toluene. Nke mbụ, a na-agwakọta toluene na sulfuric acid gbanyere mkpọrọgwụ n'ihu nitric acid wee meghachi omume na okpomọkụ kwesịrị ekwesị maka oge ụfọdụ iji nweta ngwaahịa, nke a na-edozi usoro ndị ọzọ nke crystallization, filtration na ihicha ka n'ikpeazụ nweta 4- methyl-2-nitrophenol.
Ozi nchekwa:
4-Methyl-2-nitrophenol bụ ihe na-egbu egbu nke na-agbakasị ahụ ma na-emebi emebi. Ngosipụta ya nwere ike ịkpata mgbakasị anụ ahụ, mgbakasị anya anya na mgbakasị akụkụ iku ume. Ya mere, mgbe ị na-eji ma ọ bụ na-ejikwa ya, ị kwesịrị iyi ihe nchebe kwesịrị ekwesị, dị ka uwe aka, enyo nchebe na ihe nchebe iku ume ka ịzenarị kọntaktị ozugbo na iku ume. Tụkwasị na nke ahụ, ọ bụ ihe na-ere ọkụ na ekwesịrị ka ewepụ ya na ọkụ na isi mmalite okpomọkụ. N'oge nchekwa na njem, ekwesịrị ịkpachara anya ka ị ghara ịgwakọta ya na oxidants na combustibles. N'okpuru ọgwụgwọ na-ekwesịghị ekwesị, ọ nwere ike ịkpata mmetọ na imerụ gburugburu ebe obibi. Ya mere, ekwesịrị ịgbaso usoro nchekwa dị mkpa iji hụ na ojiji na mkpofu nke ogige ahụ kwesịrị ekwesị.
