Markab 10 m3 wax lagu dhimayo oo leh hawo-qaboojiye reflux, 1800 L oo biyo ah, 500 L oo ah 20% xalka maadada chloride iyo 800 kg ee budada birta laga soo helay qaybtii hore ayaa lagu daray. Kiciyeyaasha ayaa la bilaabay oo xalka waxaa loo keenay karkariyo kuleylka kuleylka tooska ah. 20 saacadood gudahood 2500 L (2800 kg) oo ah 4-nitro m-xylene iyo 2500 kg oo budada birta ah ayaa lagu daray dhimista, xaddiga ku darista ayaa loo habeeyay si ay iskujirku u karkarayo, uumi ayaa loo baahnaa kaliya bilowga iyo dhamaadka. Uumiga ka soo baxa dhimidda ayaa isku ururinaysa mashiinka serpentine waxaana dib loogu soo celiyaa dhimista (iyada oo loo marayo makiinad, lagu qaso 4-nitro m-xylene) halka lagu daro dheecaanka nitro qaabkan si loo soo saaro hoos u dhig aamusnaan ah. Marka muunadda isku soo uruurisa tijaabada ay ka madax bannaan tahay xylene, dhimista ayaa dhammaata oo la walaaqaa 4-5 saacadood oo kale.
Tijaabooyin: Muunado ayaa laga soo qaadaa yareynta hawo-qaadista uumiga, saliidda ka soo baxda jajabka waa inuu noqdaa mid aan midab lahayn oo soo saara xal cad oo ay ku jirto aashitada hydrochloric
Soo saarida: waxyaabaha ka soo baxa qalabka yareeya ayaa lagu cadaadiyey soo saaraha waxaana lagu daaweeyaa 6000 L oo benzene ah 60 ° C oo la walaaqay, isku dar ah ayaa la walaaqaa 1 saac oo loo daayaa inuu istaago 1 saac. Xiriirka u dhexeeya biyaha iyo barafka waxaa lagu go'aamiyay in la quusiyo xarig lagu xirey dabaasha benzene laakiin dul sabeynaya biyaha, yacni, qoto dheer dusha jiifka. Hal garaam oo tuubada quusin ee nidaamsan ayaa hoos looga dhigay heerka cabirka, iyo lakabka sare ee benzene ayaa lagu riixayaa haanta leh nitrogen. Soo saaritaankan waxaa la sameeyaa 6-7 jeer, soo saaristu waa dhameystiran tahay marka kaliya 3-5 kg ​​ee m-xylene amine ay ku harto soosaaraha.
Saddexda soo-saar ee ugu horreeya oo leh jiir khaas ah oo qiyaastii ah 0.96, 0.925 iyo 0.90 ayaa loo dirayaa hawo-mareenka ka soo kabashada benzene, iyo dhowrka soo socda ee soo socda oo leh culeysyo gaar ah oo ka hooseeya 0.90 ayaa loo isticmaalaa inay yihiin soosaarayaashii ugu horreeyay, labaad iyo saddexaad ee dufcadda xigta. Xalka benzene ee xylenolamine ayaa loogu tagay haanta keydka waxaana loo dirayaa sariirta dhalada, halkaas oo benzene lagu uumiyey laguna celiyo qeybta soo saarista si loogu sii isticmaalo. Xylenolamine wuxuu weli kujiraa tuubbada qulqulka.
Haraaga wajiga aqueous ee soo saarida uumiga soosaarka ee 4-5 saacadood si looga soo kabsado benzene, ka dibna isku dar dhan oo leh cadaadis hawo oo lagu galiyo kala-qeybaha beerta, cadaadiska salka hoose ee kala-bixiyaha si uu u dhaafo biyaha, u dhaafo xawaaraha biyaha si loo sameeyo oksaydh bir sabaynaysa, iyada oo laga soo baxayo dusha sare ilaa haanta kaydinta dhoobada birta, halkaas oo ay ka baxaan dheecaanka biyaha wasakhaysan.
Qashinka birta ah ee aan wax laga qaban, kana culus birta xabagta, wuxuu hoos ugu dhaadhacayaa qeybta hoose ee kala-sooca dhul-gooyada ah ee xaddiga ah 800-1000 kg waxaana dib loogu soo celiyey qaybtii xigtey ee sibidhka yareynta.
Kala saarida: Sheyga ceyriinka ah ee ka soo baxa khaanadda muxaadarooyinka, ka dib marka laga saaro benzene, waxaa loo wareejiyaa kettleil kale oo shax leh, halkaas oo lagu sifeeyay hal hawo oo ah 20-30 mm iyo 125-135 ° C. Waxtarka muxaadaro waa 97-98%. Waxtarka jajabka ayaa ahaa 97-98%.
Wadarta wax soo saarku waa 90-91%. Muxaadarooyinka ka dib, m-Xylene-4-aniline waa inuu noqdaa mid huruud ah oo midab jaalle ah. Xalka ku jira aashitada hydrochloric waa inuu ahaadaa mid cad.

Nidaamka hawlgalka: (saamiga maaddada: waxyar). Kudar biyo, hydrochloric acid iyo budada birta ku shub dhalada 3000 ml oo ah qalabka walaaqaya iyo kuwa soo celinaya, walaaq ilaa 15 daqiiqo, ka dibna si tartiib ah u kordhi heerkulka 90-98 ℃ oo bilow inaad ku darto nitroxide. Haddii nitroxide uu baaba'o, ka dib sii wad inaad ku darto nitroxide, badiyaa saacadaha 1.5-2. Ka dib markaad ku darto nitroxide, ku hay falcelinta heerkulka kor ku xusan 2-2.5 saacadood, illaa iyo inta osmosis huruudku baaba'ayo oo aysan jirin wax ur ah nitroxide, falcelinta dhimista ayaa gaari doonta dhammaadka. Ka dib u qabooji 40-50 ℃, ku dar sodium carbonate oo kala-bax pH 7.5-8, ka dibna ku cabir jawaab-bixiyeyaasha dhexdhexaadka ah ee ku jira warqadda miiraha leh xalka aaladda alkalide.
Sannadkii 2000 ml oo ah saddex dhalo oo lagu soo gaabiyey yaraynta fal-celiyayaasha, ka hor inta aanad riixin weel sagxad ah oo hoostiisa ah dhaliyaha uumiga uumiga, oo ay ku xigto isku-uruuriyaha tubbada tooska ah, hawo-qabeyaha gadaashiisa xambaarsan, markii la dhimay dhalada saddexda af leh, kululaynta foornada korontada, marka uu sitaha wasakhda buuxda, u gudub qolka dareeraha ah si loogu kala saaro lakabyo, am-xylene amines banaanka loo saaro, ka dibna loo miisaamo in la falanqeeyo.

Waa in la sheegaa: Warshaddii hore ee Dye lama dhoofin jirin, sidaa darteed CA ma soo saarin, mana jirto cid Shiinaha ka tirsan oo diiwaan gelisay illaa iyo hadda, sidaa darteed Xarunta Macluumaadka Kiimikada ee Shiinaha wax kama oga arrintaas!
