sawubona, lo yi-CEO athena evela embonini ye-mit-ivy yamakhemikhali e-china.

I-Jiangsu organic chemical (okuhlanganisa odayi) amabhizinisi okukhiqiza, ngokuya ngezidingo zawo, ukukhiqizwa nodayi (okuhlanganisa nesibulala-zinambuzane) imikhiqizo esekela abaphakathi. IRiphabhulikhi yeminyaka engama-37 (1948), iNanjing Chemical Plant, ukukhiqizwa kwecala le-dinitrophenol, abaphakathi bokuqala besifundazwe, yabe isimisa ukwakhiwa nokukhiqiza ngenxa yokuphuthuma kwempi. Ngemva kokusungulwa kwe-People's Republic of China, ngokuthuthukiswa kwemboni yendwangu elula, kusukela “Ohlelweni Lwesibili Lweminyaka Emihlanu”, ukukhiqizwa kokudayi nakho sekuthuthukisiwe. Ekupheleni kuka-1987, abaphakathi bakha uchungechunge oluthathu lwe-naphthalene, benzene kanye ne-anthracene.

Uhlelo lweNaphthalene i-Methyl naphthalene amine, i-Changzhou Dyestuff Factory yafakwa ekukhiqizeni ngo-1962, ngokukhishwa kwenyanga okungaba ngamathani ayi-10. Ngo-1964, indawo yokusebenzela yasefekthri yasuswa, inqubo yashintshwa, izimo zokusebenza zashintshwa, futhi umphumela wonyaka wanda waba amathani angama-500. 1973 July, methyl naphthalene amine njengoba iphrojekthi exchange angaphandle, ukutshalwa kwezimali yuan 138,300,000, owokuqala e-China ukushintsha ukuncishiswa ngezikhathi ezithile inqubo yokunciphisa okuqhubekayo, ukuze okukhipha yonyaka anda ukuze 1000 amathani, inqubo isaqhubeka kuze kube yilolu suku. Ngo-1979, lesi sitshalo saphinde saguqula imishini, sanweba indawo yokupholisa, salungisa umbhoshongo wokupakisha we-steamer owela phansi, ukuze izinga lomkhiqizo lithuthuke kakhulu. 1983, i-methyl naphthalene amine yaba umkhiqizo wesithathu emlandweni wesitshalo ukukhiqiza inzuzo yonyaka ye-yuan eyisigidi. Ngo-1985, i-methyl naphthalene amine yalinganiswa njengemikhiqizo yekhwalithi ephezulu esifundazweni saseJiangsu. 1987, isitshalo self-ngezimali yuan 570,000, futhi waphinde wandisa ukukhiqizwa kanye noguquko, okukhiphayo ekupheleni konyaka kwafinyelela amathani 2706, okukhipha Total 25715 amathani. I-Methylnaphthylamine ithunyelwe emazweni angaphandle kusukela ngo-1981, futhi ekupheleni kuka-1987, inani eliphelele lokuthumela ngaphandle lalingamathani ayi-1343, okuwumkhiqizo okhethekile ohlelweni lwesifundazwe. Ngaphezu kwe-methylnaphthylamine, isitshalo esasetshenziswa ukukhiqiza i-methylnaphthol (lapho i-Changzhou Pesticide Factory isungulwa ngo-1971, yabelwa i-Changzhou Pesticide Factory ukuze ikhiqize.) Ngo-1972, yakhiqiza i-ethylnaphthol, eyanqanyulwa ngo-1980 ngenxa yokulungiswa komkhiqizo.

Ngaphezu kwalokho, i-Nanjing Chemical Factory yafaka ekukhiqizeni i-Tucson acid ne-J acid ngo-1959 no-1960, ngokulandelana, futhi yathuthukisa i-ethylnaphthol ngo-1965 kanye ne-methylnaphthol ngo-1984. I-Suzhou Dyestuff Factory yafaka ekukhiqizeni isilingo i-nivenic acid ne-L-acid ngo-1965 County Dongfe Wungjiang. I-Chemical Factory yakhiqiza i-tollibex ngo-1970. I-Rudong County Chemical Factory kusukela ngo-1979, ukukhiqizwa kwesilingo semikhiqizo emisha ye-H acid, i-ethyl naphthol, usawoti we-amino C, usawoti ka-R, njll. Ngo-1985, izimali zokuthuthukisa ubuchwepheshe ezizikhokhela ngama-yuan ayizigidi ezingu-3, ​​ngakho-ke. ukuthi umthamo wonyaka wokukhiqiza wesitshalo wamathani angu-4,000, usawoti ka-R ngo-1987 waqanjwa ngokuthi imikhiqizo yekhwalithi yeSifundazwe saseJiangsu. 1987 iRudong County Chemical Factory dyestuff intermediates ukuthunyelwa kwamanye amazwe kwafinyelela ku-2.4 million US dollars.

Uhlelo lwe-Benzene Kunezinhlobonhlobo eziningi zalezi ziphakathi, ezikhiqizwa ikakhulukazi yi-Nanjing Chemical Factory, ezinye zazo zichazwe esahlukweni esithi "imboni yamakhemikhali ephilayo" kulo magazini.

Umkhiqizo wokuqala ohlelweni lwe-benzene yi-dinitrophenol, ekhiqizwa yi-Nanjing Chemical Factory, eyandulela i-Central Chemical Factory eRiphabhulikhi yaseChina eminyakeni engu-37 ngemva kokukhiqizwa kwesivivinyo samathani ayi-10 e-Jing Plant. NgoJulayi ka-ROC 38, iNanjing Chemical Plant yaphumelela ekukhiqizeni isilingo se-dinitrochlorinated benzene, ngokukhishwa kwethani elingu-1 kuleyo nyanga. I-Dinitrochlorobenzene yayiwumkhiqizo oyinhloko wokukhiqizwa kwe-sulfide element, eyayingeniswa kakhulu evela e-United States ngaleso sikhathi. Ukuze aphule ukuvinjelwa kwezomnotho wase-US futhi alondoloze indlela yokuziphilisa yesitshalo, i-Nanjing Chemical Plant, ngaphansi kwezimo ezinzima kakhulu zemali, imishini kanye nobuchwepheshe, ithembele kubasebenzi ukuba banyakaze izinto ngezinduku zokhuni nezinye izindlela zomdabu, ukuze ukukhishwa kwe-benzene ye-dinitrochlorinated kufinyelele amathani ayi-15.5 ngalowo nyaka. Ngo-1951, umbuso watshala ama-yuan ayizigidi eziyizinkulungwane eziyi-1.8 (okulingana no-180,000 yuan) embonini, ukwakhiwa kwemishini yokukhiqiza i-dinitro, wamukele abasebenzi abadalwe "NgoJulayi 1956, isitshalo sesitshalo "amino" saqedwa, kanye nezinhlobo eziyi-10 zemikhiqizo enjalo. njengoba i-p-aminophenol yafakwa ekukhiqizeni. Ngo-1959, ukukhishwa kwe-dinitro ammoniated benzene kwafinyelela kumathani ayi-1885. Ngemva kweminyaka engu-3 yokulungiswa komnotho, ngokushintshwa kwezinhlobonhlobo ze-dyestuff, lesi sitshalo sakha ezinye izixhumanisi zochungechunge lwe-benzene ngokulandelana. Ngasekupheleni kweminyaka yama-70s, ngokulungiswa kwemikhiqizo ye-sulfur dyestuff, ukukhishwa kwe-dinitrochlorobenzene kwehla unyaka nonyaka, futhi kwakhiqizwa amathani angu-667 kuphela ngo-1987. Ngokuphambene, ukuthuthukiswa kwe-aniline ngo-1958 kwakungenxa yokuthuthukiswa kwe-disperse dyestuffs nezinye. ukukhiqizwa nokudayiswa, futhi umphumela wafinyelela amathani angu-5971 ngo-1987.

Ngaphezu kokukhiqizwa kochungechunge lwe-benzene intermediates eNanjing Chemical Plant, iWuxi Dyestuff Factory iphinde yafaka ekukhiqizeni i-dinitrochlorinated benzene (self-matching) ngo-1963, i-p-nitroaniline ne-p-nitrochlorinated benzene ngo-1966, kanye ne-phenyl peridothenic acid ne-hexachloroanthraquinone ngo-1973. ; I-Nanjing Dyestuff Factory yakhiqiza i-p-aminophenol ngesisekelo sokuhlolwa ngo-1966; I-Changzhou Auxiliary Plant ifakwe ekukhiqizeni i-diphenylamine ngo-1966; I-Rudong Chemical Plant yakhiqiza i-hydroquinone ngesisekelo sokuhlolwa ngo-1974; I-Changzhou Chemical Plant yakhiqiza i-hydroquinone ngesivivinyo ngo-1974. Ngo-1976, i-Provincial Bureau of Combustion and Chemical Industry yatshala amayuan ayizigidi ezingu-1.9 eWuxi Dyestuff Factory ukuze kwandiswe umthamo wonyaka wokukhiqiza we-phenyl peri-acid nokwakha itoluene entsha engamathani ayi-100. -based peri-acid plant. Umnyango Wemboni Yamakhemikhali kanye Nehhovisi Lesifundazwe Lokushisisa Nemboni Yamakhemikhali utshale izigidi ezingu-4.18 zamayuan ukuze kwakhiwe umthamo waminyaka yonke wamathani angu-3,000 wesitshalo se-mononitrotoluene e-Jiangsu.

I-anthracene system I-anthracene intermediate isetshenziswa kakhulu njengezinto ezingavuthiwe zokukhiqiza odayi abanciphisa. Ngo-1972, iXuzhou Dyeing and Chemical Plant yaqala ukukhiqiza iquinone engancibiliki nge-chlorinated, kwathi ngo-1976, yakhiqiza i-quinone eyi-amino engancibiliki eyi-1 ngesikhathi sokuhlolwa; ngo-1975, i-Changzhou Dyeing Plant yakha isitshalo esisha sokunciphisa udayi futhi yafakwa ekukhiqizeni i-1.4 diamino anthraquinone, 1-chloro anthraquinone neminye imikhiqizo; I-Wuxi Dyeing Plant nayo yayinemikhiqizo yochungechunge lwe-anthracene ukusekela ukukhiqizwa kokudayi esitshalweni. Kuze kube ngu-1987, ngenxa yokushintshwa kwesakhiwo somkhiqizo we-dyestuff, ukukhishwa kwemikhiqizo yochungechunge lwe-anthracene kwakungamathani angama-338 kuphela, futhi amathani angu-120 athunyelwa ngaphandle.

Izibalo Zokukhiqiza ze-Jiangsu Dyestuff kusukela ngo-1955 kuya ku-1977
