Uburyo bwa Synthesis
1.Uburyo bwa Hydrolysis: o-nitrochlorobenzene ni hydrolyzed na acide na sodium hydroxide yumuti.Ongeramo 1850-1950 l ya 76-80 g / L sodium hydroxide yumuti mumasafuriya ya hydrolysis, hanyuma wongereho kg 250 ya o-nitrochlorobenzene.Iyo yashyutswe kugeza 140-150 ℃ kandi umuvuduko ni 0.45MPa, komeza kuri 2.5h, hanyuma uzamure kuri 153-155 ℃ naho umuvuduko uri 0.53mpa, hanyuma ubigumane kuri 3h.Nyuma yo kubyitwaramo, yarakonje kugeza kuri 60 ℃.Ongeramo amazi 1000L hamwe na 60L yibanze ya acide sulfurike muri kristaliste mbere, hanyuma ukande muri hydrolyzate yavuzwe haruguru, hanyuma wongereho buhoro buhoro aside sulfurike kugeza impapuro zapimwe zitukura za congo zihindutse ibara ry'umuyugubwe, hanyuma ushyiremo urubura kugirango ukonje kugeza kuri 30 ℃, kuvanga, kuyungurura, no kunyeganyega hanze inzoga za nyina hamwe na centrifuge kugirango ubone 210 kg o-nitropenol irimo 90%.Umusaruro uri hafi 90%.Ubundi buryo bwo gutegura ni nitrasi ya fenolu ivanze na o-nitropenol na p-nitropenol, hanyuma ukayungurura o-nitropenol hamwe numwuka wamazi.Nitrification yakozwe kuri 15-23 ℃ kandi ubushyuhe ntarengwa ntibugomba kurenga 25 ℃.
Nitrasi ya fenol.Fenol ihindurwamo aside nitricike kugirango ikore imvange ya o-nitropenol na p-nitropenol, hanyuma itandukanijwe no kuyungurura amavuta.
Gusaba
Irashobora gukoreshwa nkigihe gito cyo guhuza ibinyabuzima nkubuvuzi, dyestuff, umufasha wa reberi nibikoresho bifotora.Irashobora kandi gukoreshwa nkigipimo kimwe cya pH.
Uburyo bwo kubika
Ububiko bufunze mububiko bukonje kandi buhumeka.Irinde umuriro nubushyuhe.Igomba kubikwa ukwayo na okiside, reductant, alkali n imiti iribwa, kandi ububiko buvanze bugomba kwirindwa.Ibikoresho byo guturika no guhumeka byemewe.Birabujijwe gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.Ahantu ho guhunika hagomba kuba hafite ibikoresho bikwiye kugirango bisohoke, kure y’isoko ry’ubushyuhe, ibishashi n’umuriro ugurumana kandi biturika.
Ibyitonderwa
Igikorwa gifunze kugirango gitange umuyaga uhagije waho.Abakoresha bagomba gutozwa byumwihariko kandi bakubahiriza byimazeyo imikorere.Birasabwa ko abashoramari bagomba kwambara ubwiyungurura-bwungurura ubwoko bwumukungugu, ibirahuri byumutekano wimiti, imyenda yakazi yo kurwanya uburozi hamwe na gants ya rubber.Irinde umuriro nubushyuhe.Nta kunywa itabi ku kazi.Koresha sisitemu yo guhumeka hamwe nibikoresho.Irinde umukungugu.Irinde guhura na okiside, kugabanya agent na alkali.Iyo itwaye, igomba gupakirwa no gupakururwa byoroheje kugirango ibuze paki n'ibikoresho byangirika.Ibikoresho byo kurwanya inkongi zumuriro zingana nubwinshi hamwe nibikoresho byihutirwa byihutirwa.Ibikoresho birimo ubusa bishobora kuba birimo ibintu byangiza.
