mhoro, uyu ndiye CEO athena anobva ku mit-ivy industry yemakemikari mu china.
Vepakati: Dyestuff yepakati ibazi rakakosha zvakanyanya reiyo yakanaka indasitiri yemakemikari, uye kukurumidza kusimudzira kweindasitiri yedhayi kunoenderana nekuvandudzwa kweiyo yepakati inoenda nayo.
Kugadzirwa kwedhayi uye pigment yepakati muChina kwakagadziridzwa zvakanyanya kubva kuma1950s.Nekukwikwidza kuri kuwedzera kunotyisa mumusika, dyestuff uye pigment intermediates zvakagadziridzwa mukugadzira tekinoroji;vakaita budiriro muzvinhu zvakati wandei zvakaita sekugadzira mhando nyowani, kuvandudza nzira yekugadzira, kutsvagisa nzira nyowani, mashandisirwo matsva emhando dzekare, kuchengetedza zvakatipoteredza, nezvimwewo, uye kutora tekinoroji yakachena yekugadzira dhayi uye pigment intermediates.

Kuvandudzwa kwekushandiswa kwepakati

Muchokwadi, kushandiswa kweyepakati kusimudzira kune akawanda, imwe yepakati inoshandiswa mudhayi inonzi dye intermediates, uye inoshandiswa mumishonga yezvipembenene, mishonga uye inonzi mishonga yezvipembenene, mishonga yepakati.Vepakati vanofanirwa kutariswa sebazi reiyo yakanaka makemikari indasitiri yakazara, haifanirwe kugovaniswa yakakamurwa kuita dyestuff intermediates, pesticide intermediates, mishonga yepakati neindasitiri, izvo zvinoderedza chiyero chekushandiswa kwevamwe vepakati uye kukanganisa kukura kwavo.

Yakanaka kemikari yepakati tsvakurudzo inoratidzirwa nemhando dzakasiyana-siyana, kuwedzera kune mashoma mashoma emhando yekugadzira yakakura zvakanyanya, mazhinji emhando dze tonnage haana kukura zvakanyanya, asi maitiro ekugadzirira anowanzo kuoma, anosanganisira akawanda mayuniti maitiro uye kupatsanurwa maitiro. , kugadzirwa kwakaunzawo nhamba yakati kuti ye "tsvina nhatu" dzinoda kubatwa nemazvo.Naizvozvo, isu tinofanirwa kuita tsvakiridzo yezvigadzirwa zvakatevedzana uye kuronga kugadzirwa kwezvepakati zvine musoro kuti tiwane mabhenefiti akanaka.

Kubva pamamiriro ezvinhu enyika dzekunze, kutsvagisa uye kugadzirwa kwevapakati kunowanzo kuve kwakanyatso kutariswa kuti uwane akateedzana kugadzirwa, seti yezvigadzirwa zvekugadzira inogona kuburitsa akati wandei kusvika gumi nemaviri emhando dzepakati, kutsvagisa kwakadaro uye kugadzira kuburikidza nekukura kwese. tekinoroji nyowani iri nyore kuita, ichawana zvakapetwa kaviri mhedzisiro nehafu yekuedza.Mamiriro ezvinhu eJapan anogona kunge ari ekutaura kwedu, kugadzirwa kwepakutanga kwevapakati muJapan zvakare kwakapararira kwazvo, kubva kuma1960 kwave kanomwe kugadzirisa, kutarisa.

Kuburikidza neshanduko nekusimudzira, indasitiri yekudhayira uye pigment yepakati indasitiri yasvika padanho repamusoro maererano nechiyero chekugadzira, tekinoroji uye nhanho yemidziyo, iyo isingagone kuzadzisa zvinodiwa zvekusimudzira indasitiri yedhayi uye pigment, asiwo inopa humwe hutano hwepakati. kune dzimwe nyika.

Iyo mbishi inodiwa pakugadzira yepakati inonyanya kuwanikwa kubva kune zvigadzirwa zvepetroleum uye coking kemikari indasitiri, mazhinji acho ari benzene, naphthalene, anthraquinone makomisheni, uye mamwe macompound heterocyclic, uye organic pigments yakagadzirwa neheterocyclic compounds yepakati. kuwedzera mumakore achangopfuura.Mukuwedzera, phenanthrene, pyridine, oxygen fluorene, quinoline, indole, carbazole, biphenyl series of compounds, izvi zvakaoma zvakasvibiswa zvinoshandiswa pakugadzirwa kwedhayi, zvino kushandiswa kwezvigadzirwa zvekugadzira zvichange zvakapararira uye zvakajairika.

Izvo zvinowanzoitika kemikari maitiro anoshandiswa kune epakati

Kugadziriswa kwezvinhu zvakasvibirira kuita dhayi (ruvara) zvepakati pezvinowanzo shandiswa kemikari maitiro ndeaya anotevera.
(1) sulfon reaction
(2) Nitration reaction
(3) halogenation reaction
(4) Kuderedza kuita kwekugadzirira amino
(5) Diazotization reaction (kazhinji inoperekedzwa nekubatanidza kuita)
(6) alkali fusion reaction kutsiva sulfonic acid boka kune hydroxyl
(7) Acylation reaction
(8) Oxidation reaction
(9) condensation uye carbonation reaction
(10) Aromatization maitiro (kunyanya amino)
(11) mutual replacement reaction yehydroxyl uye amino mapoka
(12) hydroxyl kana amino hydrocarbonation reaction
Zvinoenderana nechimiro chemhete huru inonhuhwirira yeakanaka kemikari yepakati, iyo yepakati inogona kukamurwa kuita aliphatic system, benzene system, naphthalene system, anthraquinone system, heterocyclic system uye gobvu mhete system.Nyika yedu inogona kugadzira anopfuura mazana mana emhando dzepakati senge benzene, naphthalene, anthraquinone, heterocyclic uye kumwe kudhaya uye pigment intermediates, izvo zvinonyatso kuzadzisa zvinodiwa zvekusimudzira dhayi uye pigment indasitiri.
