IJiangsu organic chemical (kubandakanywa idayi) amashishini okuvelisa, ngokweemfuno zawo, imveliso kunye nedayi (kubandakanywa nepesticide) iimveliso ezixhasa abaphakathi. IRiphabhlikhi ye-37 yeminyaka (1948), i-Nanjing Chemical Plant, imveliso yovavanyo lwe-dinitrophenol, i-intermediates yokuqala yephondo, kwaye yamisa ukwakhiwa kunye nemveliso ngenxa yokukhawuleza kwemfazwe. Emva kokusekwa kweRiphabhlikhi yaBantu baseTshayina, ngophuhliso loshishino lwamalaphu olula, ukusuka “kwiSicwangciso seMinyaka emiHlanu seSibini”, ukuveliswa kwedayi kuye kwaphuhliswa. Ekupheleni kuka-1987, abaphakathi baye benza uluhlu oluthathu lwe-naphthalene, benzene kunye ne-anthracene series.

Inkqubo yeNaphthalene I-Methyl naphthalene amine, i-Changzhou Dyestuff Factory yafakwa kwimveliso ngo-1962, kunye nemveliso yenyanga malunga neetoni ezili-10. Ngowe-1964, indawo yokusebenzela yomzi-mveliso yafuduswa, inkqubo yahlaziywa, iimeko zokusebenza zatshintshwa, yaye imveliso yonyaka yanyuswa yaya kutsho kwiitoni ezingama-500. NgoJulayi 1973, i-methyl naphthalene amine njengeprojekthi yotshintshiselwano lwangaphandle, utyalo-mali lwe-138,300,000 yuan, owokuqala e-China ukuguqula ukucutha okuphakathi ukuya kwinkqubo yokunciphisa okuqhubekayo, ukuze imveliso yonyaka yanda ukuya kwiitoni ze-1000, inkqubo iyaqhubeka nanamhla. Ngomnyaka we-1979, isityalo kwakhona saguqula izixhobo, sandisa indawo yokupholisa, salungisa i-steamer ezantsi kwinqaba yokupakisha, ukwenzela ukuba umgangatho wemveliso uphuculwe kakhulu. Ngo-1983, i-methyl naphthalene amine yaba yimveliso yesithathu kwimbali yesityalo ukuvelisa inzuzo yonyaka yesigidi esinye seyuan. Ngo-1985, i-methyl naphthalene amine yalinganiswa njengemveliso ekumgangatho ophezulu kwiPhondo laseJiangsu. 1987, isityalo self-ngemali 570.000 yuan, kwaye kwakhona yandisa imveliso kunye notshintsho, isiphumo sokuphela konyaka yafikelela 2706 iitoni, isiphumo Iyonke iitoni 25715. I-Methylnaphthylamine iye yathunyelwa kumazwe angaphandle ukususela ngo-1981, kwaye ekupheleni kuka-1987, inani elipheleleyo lokuthumela ngaphandle laliyi-1343 yeetoni, eyimveliso ekhethekileyo kwisicwangciso sephondo. Ukongeza kwi-methylnaphthylamine, isityalo esisetyenziselwa ukuvelisa i-methylnaphthol (xa i-Changzhou Pesticide Factory yasungulwa kwi-1971, yabelwa kwi-Changzhou Pesticide Factory yokuvelisa.) Kwi-1972, yavelisa i-ethylnaphthol, eyayekwa kwi-1980 ngenxa yokulungiswa kwemveliso.

Ukongeza, i-Nanjing Chemical Factory ifake kwimveliso ye-Tucson acid kunye ne-J acid kwi-1959 kunye ne-1960, ngokulandelanayo, kwaye iphuhlise i-ethylnaphthol kwi-1965 kunye ne-methylnaphthol kwi-1984. I-Suzhou Dyestuff Factory ifake kwimveliso yovavanyo lwe-nivenic acid kunye ne-L-acid kwi-1965 County Dongfe Wungjiang. I-Chemical Factory yavelisa i-tollibex ngo-1970. iRudong County Chemical Factory esuka kwi-1979, imveliso yovavanyo lwemveliso entsha ye-H acid, i-ethyl naphthol, ityuwa ye-amino C, ityuwa ye-R, njl. ukuba umthamo wonyaka wemveliso yesityalo seetoni ezingama-4,000, ityuwa ye-R ngo-1987 yabizwa ngokuba yimveliso esemgangathweni yePhondo laseJiangsu. Ngo-1987 iRudong County Chemical Factory Factory dyestuff intermediates ukuthunyelwa kumazwe angaphandle kwaba yi-2.4 yezigidi zeedola zaseMelika.

Inkqubo yeBenzene Kukho iintlobo ezininzi zezo ziphakathi, eziveliswa ikakhulu yiNanjing Chemical Factory, ezinye zazo zichazwe kwisahluko "seshishini lemichiza ephilayo" kweli phephancwadi.

Imveliso yokuqala kwinkqubo ye-benzene yi-dinitrophenol, eveliswa yi-Nanjing Chemical Factory, eyandulela i-Central Chemical Factory kwiRiphabhliki yaseChina kwiminyaka eyi-37 emva kokuveliswa kovavanyo lweetoni ezili-10 zeJing Plant. NgoJulayi we-ROC 38, iNanjing Chemical Plant iphumelele kwimveliso yovavanyo lwe-dinitrochlorinated benzene, kunye nemveliso ye-1 ton kuloo nyanga. I-Dinitrochlorobenzene yayiyeyona nto iphambili kwimveliso ye-sulfide element, eyayithengwe kakhulu evela e-United States ngelo xesha. Ukuze ukwaphule uthintelo lwezoqoqosho e-US kwaye ugcine ubomi besityalo, iNanjing Chemical Plant, phantsi kweemeko ezinzima kakhulu zenkunzi, izixhobo kunye nobuchwepheshe, wathembela kubasebenzi ukuba bavuselele izinto ngeentonga zomthi kunye nezinye iindlela zemveli, ukuze imveliso ye-dinitrochlorinated benzene yafikelela kwi-15.5 yeetoni ngaloo nyaka. Ngo-1951, urhulumente watyala imali eyi-1.8 yeebhiliyoni zeeyuan (elingana ne-180,000 yuan) kwisityalo, ukwakhiwa kwezixhobo zokuvelisa i-dinitro, yamkela abasebenzi abadalwe "NgoJulayi ka-1956, isityalo se "amino" sagqitywa, kunye neentlobo ezili-10 zeemveliso ezinjalo. njengoko i-p-aminophenol yafakwa kwimveliso. Ngo-1959, imveliso ye-dinitro ammoniated benzene yafikelela kwi-1885 yeetoni. Emva kweminyaka emi-3 yohlengahlengiso lwezoqoqosho, kunye notshintsho lweentlobo zedayi, isityalo siye savelisa ezinye ii-intermediates ze-benzene series enye emva kwenye. Ngasekupheleni kwe-70s, kunye nokulungiswa kweemveliso ze-sulfur dyestuff, imveliso ye-dinitrochlorobenzene yehla ngonyaka, kwaye kuphela iitoni ezingama-667 zaveliswa ngo-1987. Ngokwahlukileyo, ukuphuhliswa kwe-aniline ngo-1958 kwakungenxa yokuphuhliswa kwedayi edibeneyo kunye nezinye. imveliso kunye neentengiso, kwaye imveliso yafikelela kwiitoni ezingama-5971 ngo-1987.

Ukongeza kwimveliso ye-benzene series intermediates kwi-Nanjing Chemical Plant, iWuxi Dyestuff Factory yafaka kwimveliso ye-dinitrochlorinated benzene (self-matching) ngo-1963, i-p-nitroaniline kunye ne-p-nitrochlorinated benzene ngo-1966, kunye ne-phenyl peridothenic acid kunye ne-hexachloroanthraquinone ngo-1973. ; I-Nanjing Dyestuff Factory ivelise i-p-aminophenol kwisiseko sovavanyo kwi-1966; Changzhou Auxiliary Plant wafaka imveliso diphenylamine ngo-1966; I-Rudong Chemical Plant ivelise i-hydroquinone kwisiseko sovavanyo kwi-1974; I-Changzhou Chemical Plant ivelise i-hydroquinone kwisiseko solingo ngo-1974. Ngo-1976, i-Bureau yePhondo yokutshiswa kunye neShishini leMichiza yatyala imali eyi-1.9 yezigidi zeeyuan kwi-Wuxi Dyestuff Factory ukwandisa umthamo wonyaka wemveliso ye-phenyl peri-acid kunye nokwakha i-toluene entsha ye-100-toluene. -esekelwe kwisityalo se-peri-asidi. UMphathiswa woShishino lweMichiza kunye neBureau yePhondo yokuTsha kunye neShishini leMichiza lityale i-4.18 yezigidi zeeyuan ukwakha umthamo wonyaka weetoni ezingama-3,000 zesityalo se-mononitrotoluene eJiangsu.

Inkqubo ye-anthracene I-Anthracene intermediates isetyenziswa kakhulu njengezinto ezibonakalayo zokuvelisa idayi yokunciphisa. Kwi-1972, i-Xuzhou Dyeing kunye ne-Chemical Plant yaqala ukuvelisa i-quinone e-chlorine engenakunyibilika, kwaye kwi-1976, yavelisa i-quinone ye-1-amino engaxutywanga kwilingo; ngo-1975, iChangzhou Dyeing Plant yakha iplanti entsha yokunciphisa idayi kwaye yafaka kwimveliso 1.4 diamino anthraquinone, 1-chloro anthraquinone kunye nezinye iimveliso; I-Wuxi Dyeing Plant nayo yayineemveliso zothotho lwe-anthracene ukuxhasa ukuveliswa kwedayi kwisityalo. Kuze kube yi-1987, ngenxa yokutshintsha kwesakhiwo semveliso ye-dyestuff, ukuveliswa kweemveliso ze-anthracene kwakuyiitoni ezingama-338 kuphela, kwaye iitoni ezili-120 zathunyelwa ngaphandle.
