Kuvandudzwa kwekushandiswa kwepakati

Kutaura zvazviri, kushandiswa kwepakati ndiko kukura kwamativi akawanda, imwe mhando yepakati inoshandiswa mudhayi inonzi dye intermediates, uye inoshandiswa mumishonga yezvipembenene, mishonga, nezvimwewo.Inonziwo mushonga wezvipembenene, pharmaceutical intermediates.Inofanirwa kutariswa sebazi reiyo yakanaka makemikari indasitiri yakazara, haifanirwe kugovaniswa yakakamurwa kuita dhayi yepakati, pesticide intermediates, pesticide intermediates, pesticide intermediates, pesticide intermediates, pesticide intermediates, pesticide intermediates, pesticide intermediates. , mishonga yezvipembenene, mishonga yezvipembenene, mishonga yezvipembenene, mishonga yezvipembenene, mishonga yezvipembenene, mishonga yezvipembenene, inopindirana nemishonga, mishonga yezvipembenene, mishonga yezvipembenene zvepakati, zvepakati pemishonga yezvipembenene, zvepakati pemishonga yezvipembenene, zvinouraya zvipembenene, zvinouraya zvipembenene Zviri pakati, zvepakati pemishonga, izvo zvinoderedza huwandu hwekushandiswa kwevamwe vepakati uye kukanganisa maitiro avo.development.

Yakanaka kemikari yepakati tsvagiridzo inoratidzirwa neyakasiyana siyana, kunze kwekunge mashoma mashoma ekugadzira chiyero chakakura zvakanyanya, mazhinji emhando dzematoni haana kunyanya kukura, asi maitiro ekugadzirira anowanzo kuomarara, anosanganisira akawanda mayuniti maitiro uye kupatsanurwa. kugadzirwa kwehuwandu hwakawanda hwe "marara matatu" anoda kubatwa nemazvo.Naizvozvo, isu tinofanirwa kuita serial chigadzirwa process tsvagiridzo, inonzwisisika sangano repakati kuti tiwane yakanaka chiyero chekugadzira kunyatsoita.

Kubva kumamiriro ekunze, kutsvagisa uye kugadzirwa kwevepakati kunowanzo kuve kwakanyatso kutariswa kuti uwane serial kugadzirwa.mashoma kusvika gumi nemaviri emhando dzepakati, kutsvagisa kwakadaro uye kugadzira kuri nyore kuita kuburikidza nekukura kwese uye kutora matekinoroji matsva.Tichawana kaviri chigumisiro nehafu yekuedza.Tinogona kutaura nezve mamiriro emuJapan, uko kugadzirwa kwevepakati kwaimbove kwakadzikiswa zvakanyanya, kutanga kubva kuma1960.Yakagadziridzwa uye yakasimbiswa kanomwe.

Kuburikidza neshanduko nekusimudzira, dhayi yeChina uye pigment intermediates indasitiri yasvika padanho repamusoro maererano nechiyero chekugadzira, tekinoroji uye nhanho yemidziyo, iyo isingagone kuzadzisa zvinodiwa zvemukati dhayi uye pigment indasitiri yekuvandudza, asiwo inopa humwe hutano hwepakati zvigadzirwa zve. nyika dzekunze.

Izvo zvigadzirwa zvinodiwa pakugadzira zvepakati zvinonyanya kuwanikwa kubva kune zvigadzirwa zvepetroleum uye coking kemikari indasitiri, mazhinji acho ari benzene, naphthalene, naphthalene, uye naphthalene.Mumakore achangopfuura, iyo organic pigments yakagadzirwa kubva kuheterocyclic intermediates yanga ichikwira.Pamusoro pezvo, phenanthrene, pyridine, oxygen fluorene, quinoline, indole, carbazole, biphenyl series compounds, izvi zvakaoma mbishi zvinhu zvinoshandiswa pakugadzira dhayi.Iko kushandiswa kwezvinhu zvekugadzira mbishi kuchawedzera kupararira uye kwakajairika.
