molo, le yi-CEO athena evela kwishishini le-mit-ivy yekhemikhali e-china.

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 ukusuka 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 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 yokuBasa 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.
