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 ezihambelanayo zizibonakaliso eziphambili zokubhekisela. Phakathi kweemveliso ezisele zikhona, 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 ekusebenzeni kwecala. 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.
