Ukususela kwisiqingatha sesibini sonyaka, kukho ukutenxa okuphawulekayo kwindlela ye-n-butanol kunye neemveliso ezihambelana nayo, i-octanol kunye ne-isobutanol.Ukungena kwikota yesine, lo mkhwa uqhubekile kwaye wabangela uthotho lweempembelelo ezilandelayo, ukuzuza ngokungathanga ngqo kwicala lemfuno ye-n-butanol, ebonelela ngenkxaso eyakhayo yenguquko yayo ukusuka ekunciphiseni kwicala elinye ukuya kwindlela esecaleni.

Kuphando lwethu lwemihla ngemihla kunye nohlalutyo lwe-n-butanol, iimveliso ezinxulumene nazo zizalathisi eziphambili.Phakathi kweemveliso ezinxulumeneyo ezikhoyo, i-octanol kunye ne-isobutanol zinefuthe elibalulekileyo kwi-n-butanol.Kwisiqingatha sesibini sonyaka, bekukho umahluko omkhulu wexabiso phakathi kwe-octanol kunye ne-n-butanol, ngelixa i-isobutanol yahlala iphakamileyo kune-n-butanol.Lo mcimbi ube nempembelelo ebalulekileyo kunikezelo kunye nemfuno yesakhiwo se-n-butanol, kwaye ibe nefuthe kwindlela ye-n-butanol kwikota yesine.

Ukususela kwikota yesine, ngokusekelwe ekubekweni esweni kwedatha yokusebenza ephantsi, sifumene ukuba izinga lokusebenza kweyona mveliso inkulu ephantsi, i-butyl acrylate, iyancipha kakhulu, ekhokelela ekunciphiseni okubonakalayo kwimfuno ye-n-butanol.Nangona kunjalo, ngokuchasene nokungasemva kokunyuka kobonelelo, imakethi ilindele ukuba ikhonkco leshishini le-n-butanol liqokelele ngokukhawuleza uluhlu lwempahla kwixesha elizayo, okubangela ukuvutshelwa kweemvakalelo ze-bearish.Kulo mxholo, imakethi ye-n-butanol ifumene ukwehla okungaphezulu kwe-2000 yuan/toni.Nangona kunjalo, ukulindela okubuthathaka ngokwenene kuye kwadibana nenyaniso enamandla, kwaye ukusebenza kwangempela kwemarike ye-n-butanol ngoNovemba itenxa kakhulu kwizinto ezilindelwe ngaphambili.Enyanisweni, nangona ukungabikho kwenkxaso ephezulu yokusebenza ukusuka kwi-acrylate enkulu ye-butyl ephantsi, ukunyuka kwamazinga okusebenza kwezinye iimveliso ezisezantsi ezifana ne-butyl acetate kunye ne-DBP ibaluleke kakhulu, exhasa indlela yangoku ye-n-butanol ukusuka ekunciphiseni unilateral ukuya emacaleni. ukusebenza.Ukususela ekupheleni kwe-27 kaNovemba, ixabiso le-Shandong n-butanol laliphakathi kwe-7700-7800 yuan / ton, kwaye liye lathengisa emacaleni kufuphi neli nqanaba kwiiveki ezintathu ezilandelelanayo.

Kukho utoliko oluninzi lweenguqu ekusetyenzisweni okusezantsi yimarike, kodwa ukunyuka kwamazinga okusebenza kwi-plasticizer ye-DBP ephantsi yoshishino kunye nemeko eqhubekayo ye-inventory ephantsi iyaphikisana nentsebenzo yendabuko yoshishino ngexesha lexesha elide.Sikholelwa ukuba ukwenzeka kwesi siganeko singasentla sisondelelene ngokusondeleyo kungekuphela nje ngokuzaliswa ngezigaba komlambo osezantsi, kodwa nakwiimveliso ezinxulumeneyo, kwaye kunempembelelo ezinzileyo kwimarike ye-n-butanol.

Umahluko wamaxabiso owandiswayo phakathi kwe-octanol kunye ne-n-butanol ngokungathanga ngqo wonyusa ibango le-n-butanol

Kwiminyaka emihlanu edlulileyo (2018-2022), umahluko wexabiso phakathi kwe-octanol kunye ne-n-butanol yayingu-1374 yuan / ton.Xa lo mahluko wamaxabiso udlula eli xabiso ixesha elide, kunokukhokelela kwizixhobo eziguqukayo ezikhetha ukunyusa imveliso ye-octanol okanye ukunciphisa imveliso ye-n-butanol.Nangona kunjalo, ukususela ngo-2023, lo mahluko wexabiso uye waqhubeka ukhula, ufikelela kwi-3000-4000 yuan / toni kwikota yesithathu neyesine.Lo mahluko wexabiso eliphezulu kakhulu utsale izixhobo ezitshintshekayo ukukhetha ukuvelisa i-n-butanol, ngaloo ndlela ichaphazela icala lemfuno ye-n-butanol.

Ngokwandiswa komehluko wexabiso phakathi kwe-octanol kunye ne-n-butanol, izinto ezibalulekileyo zokutshintsha ziye zavela kwintsimi yeplastiki yeplastiki.Nangona umlinganiselo we-DBP kwintsimi ye-plasticizers ayibalulekanga, njengoko umehluko wexabiso phakathi kwe-octanol kunye ne-n-butanol uyanda, umehluko wexabiso phakathi kwe-DBP kunye ne-octanol plasticizers nawo ukhula rhoqo.Ngokusekelwe kwingqwalasela yeendleko, abanye abathengi bokugqibela baye bandisa ngokulinganayo ukusetyenziswa kwe-DBP, ngokunyusa ngokungathanga ngqo ukusetyenziswa kwe-n-butanol, ngelixa inani elihambelanayo le-octanol plasticizers liye lancipha.

I-Isobutanol iyaqhubeka ukuba phezulu kune-n-butanol, kunye nemfuno etshintshela kwi-n-butanol

Ukususela kwikota yesithathu, umehluko wexabiso phakathi kwe-n-butanol kunye ne-isobutanol uye watshintsha kakhulu.Ngenkxaso yayo esisiseko eyomeleleyo, i-isobutanol iye yatshintsha ngokuthe ngcembe ukusuka ekubeni ngaphantsi kune-n-butanol ukuya ekubeni phezulu kune-n-butanol njengesiqhelo, kwaye umahluko wexabiso phakathi kwezi zimbini ufikelele kwinqanaba eliphezulu kwiminyaka yakutshanje.Oku kuguquguquka kwexabiso kuye kwaba nempembelelo enkulu ekusetyenzisweni kwe-isobutanol/n-butanol.Njengoko inzuzo yeendleko ze-isobutanol plasticizers iyancipha, abanye abathengi abasezantsi bahlengahlengisa iifomyula zabo zemveliso kwaye bajike kwi-DBP kunye neenzuzo ezinkulu zeendleko.Ukusukela kwikota yesithathu, iifektri ezininzi ze-isobutanol plasticizer kumantla nakwimpuma ye-China ziye zafumana amaqondo ahlukeneyo okuhla kumazinga okusebenza, ezinye iifektri zide zajikela ekuveliseni iiplastiki ze-n-butanol, zonyusa ngokungathanga ngqo ukusetyenziswa kwe-n-butanol.
