1. Uhlalutyo lwe-Acetic Acid Imakethi yemakethi
NgoFebruwari, i-acetic acid ibonise imeko eguqukayo, kunye nexabiso lokunyuka kuqala emva koko ukuwa. Ekuqaleni kwenyanga, ixabiso eliphakathi le-acetic acid yayingama-3245 Yuan / Ton, kunye nokuphela kwenyanga, ixabiso lalingama-3183 yuan / ton, ngokuhla kwe-1.90% ngaphakathi kwenyanga.
Ekuqaleni kwenyanga, imakethi ye-acetic acid yajongana neendleko eziphezulu kunye nokuphuculwa kwemfuno. Ukongeza, ngenxa yokuhlolwa okwethutyana kwezixhobo, ukuhanjiswa kunciphile, kwaye ixabiso emantla linda kakhulu; Ukusuka embindini wenyanga ukuya esiphelweni senyanga, imarike ingena zibonelelo zingaphezulu, ikakhulu bekunzima ukuxhasa, kwaye intengiso iguqukele ukuhla. Umzila waphinda waphinda waphinda waphinda wenza umsebenzi, lonke unikezo lwazonele, kwaye ukungqubana phakathi kokunikezelwa kunye nokunyanzelwa kukhokelele ekuphulukaneni nelungelo lokufumana ixabiso. Ekupheleni kwenyanga, ixabiso eliphambili lentengiselwano ye-acetic acid yayikuluhlu lwe-3100-32 yuan / ton.
2. Uhlalutyo lwentengiso yemakethi ye-ethyl acetate
Kule nyanga, i-ethyl yase-Ethyl yasekhaya yayinoloyiko, kwaye eyona miba iphambili eShandong yaqalisa ukusebenza, kwaye ukuhanjiswa bekunyuswa xa kuthelekiswa naloo nto. I-Ethyl Acetate yacinezelwa ngokubonelelwa okukhululekileyo kunye nemfuno, ngakumbi kwiintsuku ezilishumi zokuqala, ezingaziboni izibonelelo zexabiso eliphakamileyo le-acetic acid. Ngokweenkcukacha-manani ze-Arhente yeendaba zeShishini, ukuhla kwale nyanga yayiyi-0.24%. Ekupheleni kwenyanga, ixabiso lentengiso le-Ethyl Acetate yayingu-6750-6900 Yuan / Ton.
Ukucaciswa, imeko yorhwebo ye-Ethyl Acetate Imakethi yenyanga ibonakala ibanda, kwaye ukuthengwa kwempahla yokuthengwa kwempahla kungaphantsi, kwaye uluhlu lokurhweba lwe-Yuan. Embindini wenyanga, nangona iifektri ezinkulu ziye zahlengahlengisa, ubudlelwane obuhle bobuqhetseba bulinganiselwe, kwaye uninzi lwazo lulawulwa ngaphakathi kwe-100 yuan. Iikowuteshini zolo lumenzi beendlela ezinkulu ziye zazinza, kwaye amaxabiso abanye ovelisi eJiangsus ancitshisiwe kancinci embindini wenyanga ngenxa yefuthe loxinzelelo. Abavelisi abaziintloko zeShandong bafuna ukuthunyelwa. I-bidid isabonisa ukuzithemba okwaneleyo. Nangona kukho isivumelwano seprimiyamu, ixabiso aligqithanga kwinqanaba lenyanga ephelileyo. Ixabiso lezinto ezingafunekiyo kunye ne-acetic acid yawela kumanqanaba aphakathi kunye nasemva kwexesha kwimarike, kwaye imakethi inokujongana neendleko ezimbi.
I-3. Ukuhlaziywa kweNtengiso ye-butyl acetate
Kule nyanga, i-byyl ye-butyl ye-vertate yaphinda yaqala ngenxa yokubonelela ngokuqinileyo. Ngokutsho kokubekwa kweliso kwi-Arhente yeendaba yeShishini, i-butyl acetate irose i-1.36% rhoqo ngenyanga. Ekupheleni kwenyanga, uluhlu lwexabiso le-byyl le-bterter ye-bterter yayingama-7400-7600 Yuan / Ton.
Ngokukodwa, ukwenziwa kwentsebenzo ye-acetic ye-acetic yayibuthathaka, kwaye i-N-Butanol yawa kabukhali, yehla nge-12% ngoFebruwari, eyayingalunganga kwimarike ye-bterter ye-bterter. Esona sizathu siphambili sokuba amaxabiso e-bterster engazange alandele ukwehla kukuba kwindawo yokuhambisa, inqanaba lokusebenza kwamashishini lahlala liphantsi, ukusuka kwi-40% ngoJanuwari ukuya kwi-35%. Ukubonelelwa kuhlala kuqinile. I-Dowredam Indilime-kwaye-jonga ukuba yinto ebaluleke kakhulu, intengiso kukungabikho kwesenzo, kunye nentengiselwano yee-odolo ze-bulk inqabile, kwaye imeko kwiintsuku ezilishumi ikwisihlahla. Amanye amashishini ayenyanzelwa ukuba alungise phantsi kwemeko yeendleko eziphezulu, kwaye ubonelelo lwentengiso kunye nemfuno ibingaziyo.
I-4. Ithemba lexesha elizayo le-acetic spain

Kwixesha elifutshane, imarike ixutywe nexesha elide kwaye imfutshane, ngelixa iindleko zimbi, imfuno inokuphucula. Kwelinye icala, kusekho uxinzelelo olusezantsi kwiindleko eziphakamileyo, eziza kuzisa iindaba ezimbi kwi-acetic ye-accetic acid. Nangona kunjalo, inqanaba lokusebenza le-Acetic Acetic acid kunye ne-DowysterAm Ethyl kunye ne-Obyl Estersts iphantsi ngokubanzi. Uluhlu lweempahla zentlalo luphantsi ngokubanzi. Ngokuphuculwa okuqhubekayo kwemfuno ye-terminal kwinqanaba elizayo, ixabiso le-Dowysteram Ethster, i-butyl ester kunye nezinye iimveliso zinokunyuka ngobumnene.
