Ngomhla we-30 ka-Agasti, usaphoIpropylene oxideimarike yenyuka ngokukhawuleza, ngexabiso lemarike kwi-RMB9467/ton, inyuke nge-RMB300/toni ukusuka izolo. Isixhobo samva nje se-epichlorohydrin sasekhaya siqala phantsi ukuya ezantsi, ukuvalwa okwethutyana kunye nokunyuka kwesixhobo sogcino, unikezelo lwentengiso ngequbuliso luyaqina, lubonelele ngenkxaso efanelekileyo, eyomeleleyo. Nangona i-propylene ekrwada yamva nje kunye ne-liquid chlorine imakethi yokugcina uzinzo ibuthathaka, inkxaso yeendleko ibuthathaka, kodwa imfuno yemarike esezantsi kunye ne-terminal isenamandla, iintengiselwano zemarike ziqhelekileyo, uninzi lwezityalo ezisezantsi zigcina ukuthengwa nje, kodwa uluhlu lwangoku oluphantsi lwesityalo se-cyclopropane, abavelisi be-cyclopropane bahambisa ngokutyibilikayo. Ke ngoko, ngenkxaso efanelekileyo yokubonelela okuqinileyo kwe-cyclopropane kunye ne-inventory yefektri ephantsi, ixabiso lemarike yepropylene oxide lenyuka kakhulu namhlanje. Njengoko kushicilelo lweendaba, ixabiso eliqhelekileyo lokuthumela imali kwi-East China yi-RMB9300-9500/ton; ixabiso lengxoxo yotshintshiselwano oluqhelekileyo eShandong naseMntla China yi-RMB9400-9500/ton; ixabiso lothethathethwano oluqhelekileyo eMzantsi China yi-RMB9400-9600/ton.

Kwicala lokubonelela: Kutshanje, izixhobo zeringi zasekhaya ziqale ukusebenza kumanqanaba asezantsi. Ukongeza kwizixhobo zogcino lokuvala ukuvalwa rhoqo azikaqalisi, inani lezixhobo zogcino lokuvalwa kwethutyana liye landa, unikezelo lwemarike lwaqiniswa ngokukhawuleza, abavelisi be-ring C bathunyelwa ngokutyibilikayo, uluhlu lwempahla lwasefektri lwawela kwinqanaba elisezantsi, abavelisi babambe ixabiso eliphezulu lokulungela ukubonelela ngenkxaso efanelekileyo, eyomeleleyo.

Imfuno: Ngo-Agasti, imveliso ye-cyclopropyl ye-chain chain ayizange ikhangele "igolide elithoba isilivere elineshumi" njengoko kulindelwe kwixesha eliphakamileyo lemveli, imfuno yemarike esezantsi isekho kwinqanaba elibuthathaka, imfuno yemarike ayibonakali umthamo ocacileyo. Ngeli xesha, icala elisezantsi leqela le-cyclopropyl ligxininise ekuthengeni amaxesha amaninzi, ukuthengiselana kweemarike kuthathe kancinci, kodwa ukuphuculwa kweemfuno zemarike akuzange kuhlale ixesha elide.

I-Inventory: Ngo-Agasti, ngaphezu kokuvalwa okuqhelekileyo kwezixhobo zokulondoloza, i-epichlorohydrin yasekhaya yokuvala ixesha elifutshane kunye nokugcinwa kunye nezixhobo zokulahla umthwalo zanda, umgangatho wokwakha we-epichlorohydrin wasekhaya wawuphantsi kwaye ukunikezelwa kweemarike kwaqhubeka kuqina. Ngaphantsi kwemfuno yemarike jikelele, uluhlu lwezityalo ze-epichlorohydrin lugcinwe kwinqanaba eliphantsi.

Iindleko: Kule nyanga, imarike yepropylene ekrwada ayinayo inkxaso elungileyo, ixabiso lemarike libuthathaka ukuhla, imarike yeklorini yolwelo iyaguquguquka ngenxa yeempembelelo zotshintsho kunikezelo kunye nemfuno, ukunyuka ngokubanzi, iindleko zokuvelisa indlela ye-chloranol zonyukile, kodwa ukukhula kulinganiselwe, isiphelo semali ekrwada inkxaso ngokubanzi.

Inzuzo: Ngo-Agasti, imarike yasekhaya yepropylene oxide yachatshazelwa yimfuno ebuthathaka, kwaye ixabiso lemarike lalichatshazelwa ngokucacileyo kwicala lokubonelela kunye necala lezinto eziluhlaza. Ixabiso lemarike litshintshile ngokusondeleyo kumgca weendleko zendlela ye-chlor-alcohol, kwaye indlela ye-chlor-alcohol abenzi be-cyclopropene babenomlinganiselo othile wenzuzo, ngelixa uninzi lwezinye iinkqubo zazikwimeko yokulahlekelwa. Ngenxa yoko, ngo-Agasti, amaxabiso e-cyclopropene aguquguqukayo asondele kumgca weendleko kunye nemida ye-cyclopropene ixinzelelwe kwinqanaba eliphantsi.

Kutshanje, inqanaba lokwakhiwa kwe-cyclopropene yasekhaya liphantsi, ukuvalwa okwethutyana kwezixhobo zokulungisa kunyukile, kwaye unikezelo lwentengiso luye lwaqina ngequbuliso. Ukongeza, isityalo esikhulu eMzantsi China siceba ukumisa imveliso kunye nokugcinwa malunga neveki ekuqaleni kukaSeptemba. Nangona umzi-mveliso omkhulu kumzi-mveliso werabha iCipropylene eTianjin kulindeleke ukuba uqalise kwakhona nge-1 kaSeptemba, akukho zicwangciso zokuqalisa kwakhona ezinye iiyunithi zokulungisa, kwaye unikezelo lwexesha elizayo luselulungele inkxaso. Nangona imfuno yamva nje yentengiso esezantsi kunye neyokuphela ingakhange iphuculwe, uninzi lweefektri ezisezantsi zifuna kuphela ukungena emarikeni ukuze zithenge, kodwa ngenkxaso encomekayo yobonelelo olucuthiweyo lwerabha ye-cyclopropyl kunye noluhlu lwempahla ephantsi yomzi-mveliso, iifektri zerabha ze-cyclopropyl zibambe amaxabiso aphezulu ngokuvumayo, kwaye imarike yerabha ye-cyclopropyl kulindeleke ukuba ihlale yomelele ngomso ngexabiso le-yuc/1tu.0
