Amabhizinisi okukhiqiza amakhemikhali e-organic (kufaka phakathi amadayi) eJiangsu, ngokwezidingo zawo, ukukhiqizwa kanye nemikhiqizo yamadayi (kufaka phakathi izibulala-zinambuzane) esekela amadayi aphakathi. IRiphabhulikhi yeminyaka engama-37 (1948), iNanjing Chemical Plant, ukukhiqizwa kwesilingo se-dinitrophenol, amadayi okuqala esifundazweni, bese kumisa ukwakhiwa kanye nokukhiqiza ngenxa yokuphuthuma kwempi. Ngemva kokusungulwa kweRiphabhulikhi Yabantu baseShayina, ngokuthuthukiswa kwemboni yezindwangu ezilula, kusukela ku-“Uhlelo Lwesibili Lweminyaka Emihlanu”, ukukhiqizwa kwamadayi nakho kuye kwathuthukiswa. Ekupheleni kuka-1987, amadayi aphakathi asungule uchungechunge oluthathu lwe-naphthalene, i-benzene kanye ne-anthracene.

Uhlelo lwe-naphthalene i-Methyl naphthalene amine, i-Changzhou Dyestuff Factory yafakwa ekukhiqizweni ngo-1962, ngomkhiqizo wanyanga zonke ongamathani ayi-10. Ngo-1964, indawo yokusebenzela ifektri yathuthwa, inqubo yaguqulwa, izimo zokusebenza zashintshwa, futhi umkhiqizo waminyaka yonke wanda waba ngamathani angama-500. NgoJulayi 1973, i-methyl naphthalene amine njengephrojekthi yokushintshanisa imali yangaphandle, ukutshalwa kwezimali okungu-138,300,000 yuan, okokuqala eShayina ukushintsha ukunciphisa okungapheli kube inqubo yokunciphisa okuqhubekayo, ukuze umkhiqizo waminyaka yonke wande waba ngamathani ayi-1000, inqubo iyaqhubeka nanamuhla. Ngo-1979, isitshalo saphinde sashintsha imishini, sandisa indawo yokupholisa, salungisa umbhoshongo wokupakisha we-steamer ongezansi, ukuze ikhwalithi yomkhiqizo ithuthuke kakhulu. Ngo-1983, i-methyl naphthalene amine yaba umkhiqizo wesithathu emlandweni wesitshalo ukukhiqiza inzuzo yaminyaka yonke yama-yuan ayisigidi. Ngo-1985, i-methyl naphthalene amine yalinganiswa njengemikhiqizo esezingeni eliphezulu eSifundazweni saseJiangsu. Ngo-1987, lesi sitshalo sazixhasa ngemali ngama-yuan angu-570,000, futhi saphinda sandisa ukukhiqizwa kanye nokuguqulwa, umkhiqizo wokuphela konyaka wafinyelela amathani angu-2706, umkhiqizo ophelele wawungamathani angu-25715. I-Methylnaphthylamine ithunyelwe kwamanye amazwe kusukela ngo-1981, futhi ekupheleni kuka-1987, inani eliphelele lokuthunyelwa kwamanye amazwe lalingamathani angu-1343, okuwumkhiqizo okhethekile ohlelweni lwesifundazwe. Ngaphezu kwe-methylnaphthylamine, lesi sitshalo sasisetshenziselwa ukukhiqiza i-methylnaphthol (lapho i-Changzhou Pesticide Factory yasungulwa ngo-1971, yabelwa i-Changzhou Pesticide Factory ukuze ikhiqizwe.) Ngo-1972, sakhiqiza i-ethylnaphthol, eyamiswa ngo-1980 ngenxa yokulungiswa komkhiqizo.

Ngaphezu kwalokho, iNanjing Chemical Factory yafaka ekukhiqizweni kwe-Tucson acid kanye ne-J acid ngo-1959 nango-1960, ngokulandelana, futhi yathuthukisa i-ethylnaphthol ngo-1965 kanye ne-methylnaphthol ngo-1984. ISuzhou Dyestuff Factory yafaka ekukhiqizweni kwe-nivenic acid kanye ne-L-acid ngo-1965. I-Wujiang County Dongfeng Chemical Factory yakhiqiza i-tollibex ngo-1970. I-Rudong County Chemical Factory kusukela ngo-1979, ukukhiqizwa kwesilingo semikhiqizo emisha i-H acid, i-ethyl naphthol, usawoti we-amino C, usawoti we-R, njll. Ngo-1985, izimali zokuthuthukisa ubuchwepheshe ezizimele ze-yuan eziyizigidi ezi-3, ukuze umthamo wokukhiqiza waminyaka yonke wesitshalo wamathani angu-4,000, usawoti we-R ngo-1987 waqanjwa ngokuthi imikhiqizo yekhwalithi yeSifundazwe saseJiangsu. 1987 Ukuthunyelwa kwamanye amazwe kwe-dyestuff okuphakathi kweRudong County Chemical Factory kwafinyelela kumaRandi ayizigidi ezingu-2.4.

Uhlelo lwe-Benzene Kunezinhlobo eziningi zalezi zinto eziphakathi, ezikhiqizwa kakhulu yi-Nanjing Chemical Factory, ezinye zazo zichazwe esahlukweni esithi “imboni yamakhemikhali e-organic” kulo magazini.

Umkhiqizo wokuqala ohlelweni lwe-benzene yi-dinitrophenol, ekhiqizwa yi-Nanjing Chemical Factory, eyandulela i-Central Chemical Factory eRiphabhulikhi yaseShayina eminyakeni engama-37 ngemuva kokukhiqizwa kwamathani ayi-10 eJing Plant. NgoJulayi we-ROC 38, i-Nanjing Chemical Plant yaphumelela ekukhiqizweni kokulingwa kwe-benzene ene-dinitrochlorinated, ngomkhiqizo wethani eli-1 kuleyo nyanga. I-Dinitrochlorobenzene yayiyinto eyinhloko yokusetshenziswa ekukhiqizweni kwe-sulfide element, eyayingeniswa kakhulu e-United States ngaleso sikhathi. Ukuze iphule ukuvinjelwa komnotho wase-US futhi ilondoloze impilo yesitshalo, i-Nanjing Chemical Plant, ngaphansi kwezimo ezinzima kakhulu zemali, imishini kanye nobuchwepheshe, yathembela kubasebenzi ukuthi bavuselele izinto ngezinduku zokhuni nezinye izindlela zomdabu, ukuze umkhiqizo we-benzene ene-dinitrochlorinated ufinyelele amathani ayi-15.5 ngalowo nyaka. Ngo-1951, umbuso watshala ama-yuan ayizigidigidi eziyi-1.8 (okulingana nama-yuan ayi-180,000) esitshalweni, ukwakhiwa kwemishini yokukhiqiza i-dinitro, wamukela abasebenzi abadalwe “NgoJulayi 1956, isitshalo se-“amino” sesitshalo saqedwa, kwathi izinhlobo eziyi-10 zemikhiqizo efana ne-p-aminophenol zafakwa ekukhiqizweni. Ngo-1959, umkhiqizo we-benzene e-dinitro ammoniated wafinyelela amathani ayi-1885. Ngemva kweminyaka emi-3 yokulungiswa kwezomnotho, ngokushintsha kwezinhlobo ze-dyestuff, isitshalo sathuthukisa ezinye izinhlobo eziphakathi zochungechunge lwe-benzene ngokulandelana. Ngasekupheleni kwawo-70, ngokulungiswa kwemikhiqizo ye-dyestuff yesulfure, umkhiqizo we-dinitrochlorobenzene wehla unyaka nonyaka, kwathi amathani angama-667 kuphela akhiqizwa ngo-1987. Ngokuphambene nalokho, ukuthuthukiswa kwe-aniline ngo-1958 kwakungenxa yokuthuthukiswa kwe-dyestuffs esakazekile kanye nokunye ukukhiqizwa nokuthengiswa, kanti umkhiqizo wafinyelela amathani angama-5971 ngo-1987.

Ngaphezu kokukhiqizwa kwezingxenye ze-benzene series eNanjing Chemical Plant, iWuxi Dyestuff Factory nayo yafaka ekukhiqizeni i-dinitrochlorinated benzene (eyazifanisayo) ngo-1963, i-p-nitroaniline kanye ne-p-nitrochlorinated benzene ngo-1966, kanye ne-phenyl peridothenic acid kanye ne-hexachloroanthraquinone ngo-1973; iNanjing Dyestuff Factory yakhiqiza i-p-aminophenol ngesilingo ngo-1966; iChangzhou Auxiliary Plant yafaka ekukhiqizeni i-diphenylamine ngo-1966; iRudong Chemical Plant yakhiqiza i-hydroquinone ngesilingo ngo-1974; iChangzhou Chemical Plant yakhiqiza i-hydroquinone ngesilingo ngo-1974. Ngo-1976, iProvincial Bureau of Combustion and Chemical Industry yatshala imali engu-1.9 million yuan eWuxi Dyestuff Factory ukuze kwandiswe umthamo wonyaka wokukhiqiza we-phenyl peri-acid kanye nokwakha isitshalo esisha se-peri-acid esisekelwe ku-toluene esingamathani ayi-100. UMnyango Wezimboni Zamakhemikhali kanye neHhovisi Lesifundazwe Lemboni Yokushisa Nokushiswa Kwamakhemikhali batshale imali engu-4.18 million yuan ukwakha umthamo waminyaka yonke wamathani angu-3,000 esitshalo se-mononitrotoluene eJiangsu.

Uhlelo lwe-anthracene Ama-intermediate e-anthracene asetshenziswa kakhulu njengezinto zokusetshenziswa zokukhiqiza amadayi okunciphisa. Ngo-1972, i-Xuzhou Dyeing and Chemical Plant yaqala ukukhiqiza i-quinone enganyibiliki e-chlorine, kwathi ngo-1976, yakhiqiza i-quinone enganyibiliki eyi-1-amino ngesisekelo sokuhlola; ngo-1975, i-Changzhou Dyeing Plant yakha isitshalo esisha sokukhiqiza amadayi okunciphisa futhi yafaka ekukhiqizeni i-1.4 diamino anthraquinone, i-1-chloro anthraquinone neminye imikhiqizo; i-Wuxi Dyeing Plant nayo yayinemikhiqizo yochungechunge lwe-anthracene ukusekela ukukhiqizwa kwamadayi okunciphisa esitshalweni. Kuze kube ngu-1987, ngenxa yokushintsha kwesakhiwo somkhiqizo wedayi okunciphisa, umkhiqizo wemikhiqizo yochungechunge lwe-anthracene wawungamathani angu-338 kuphela, kwathi amathani angu-120 athunyelwa kwamanye amazwe.

Izibalo Zokukhiqiza zeJiangsu Dyestuff kusukela ngo-1955 kuya ku-1977
