Technologies Innovation: Kaphatikizidwe ka Zodzikongoletsera-Grade Phenoxyethanol kuchokera ku Ethylene Oxide ndi Phenol

Mawu Oyamba

Phenoxyethanol, mankhwala omwe amagwiritsidwa ntchito kwambiri m'zodzoladzola, atchuka chifukwa cha mphamvu yake yolimbana ndi kukula kwa tizilombo toyambitsa matenda komanso kugwirizana ndi mankhwala opangira khungu. Amapangidwa mwachikhalidwe kudzera mu kaphatikizidwe ka Williamson ether pogwiritsa ntchito sodium hydroxide ngati chothandizira, njirayi nthawi zambiri imakumana ndi zovuta monga kupangika kwa zinthu, kusagwira ntchito bwino kwa mphamvu, komanso nkhawa zachilengedwe. Kupita patsogolo kwaposachedwa mu chemistry yochititsa chidwi komanso uinjiniya wobiriwira kwatsegula njira yatsopano: momwe ethylene oxide ndi phenol imagwirira ntchito kuti ipange phenoxyethanol yoyera kwambiri, yodzikongoletsera. Zatsopanozi zikulonjeza kutanthauziranso miyezo yopangira mafakitale popititsa patsogolo kukhazikika, kukhazikika, komanso kutsika mtengo.

Zovuta mu Njira Zodziwika

The tingachipeze powerenga synthesis wa phenoxyethanol kumakhudza mmene phenol ndi 2-chloroethanol mu zinthu zamchere. Ngakhale kuti ndi othandiza, njira imeneyi imapanga sodium chloride monga chotulukapo, chomwe chimafuna njira zambiri zoyeretsera. Kuphatikiza apo, kugwiritsa ntchito chlorinated intermediate kumadzetsa nkhawa zachilengedwe ndi chitetezo, makamaka mogwirizana ndi kusintha kwamakampani opanga zodzoladzola ku mfundo za "green chemistry". Kuphatikiza apo, kuwongolera kosagwirizana komwe kumachitika nthawi zambiri kumabweretsa zonyansa monga zotumphukira za polyethylene glycol, zomwe zimasokoneza mtundu wazinthu komanso kutsata malamulo.

The Technology Innovation

Kupambanaku kuli munjira ziwiri zothandizira zomwe zimachotsa ma reagents a chlorinated ndikuchepetsa zinyalala:

Kuyambitsa kwa Epooxide:Ethylene oxide, epoxide yothamanga kwambiri, imatsegulidwa ndi phenol. Chothandizira chodziwika bwino cha asidi (mwachitsanzo, zeolite-supported sulfonic acid) chimathandizira izi pansi pa kutentha pang'ono (60-80 ° C), kupewa mikhalidwe yopatsa mphamvu kwambiri.

Selective Etherification:The chothandizira amatsogolera anachita kwa phenoxyethanol mapangidwe pamene kupondereza polymerization mbali zimachitikira. Machitidwe apamwamba oyendetsera ndondomeko, kuphatikizapo teknoloji ya microreactor, kuonetsetsa kutentha kolondola ndi kasamalidwe ka stoichiometric, kukwaniritsa> 95% kutembenuka.

Ubwino waukulu wa Njira Yatsopano

Kukhazikika:Posintha ma precursors a chlorinated ndi ethylene oxide, njirayi imachotsa mitsinje yowopsa ya zinyalala. Kugwiritsiridwa ntchito kwa chothandizira kumachepetsa kugwiritsidwa ntchito kwa zinthu, kugwirizanitsa ndi zolinga zachuma zozungulira.

Chiyero ndi Chitetezo:Kusakhalapo kwa ayoni a kloridi kumatsimikizira kutsata malamulo okhwima odzola (mwachitsanzo, EU Cosmetics Regulation No. 1223/2009). Zogulitsa zomaliza zimakumana> 99.5% chiyero, chofunikira kwambiri pakugwiritsa ntchito zosamalira khungu.

Kuchita bwino pazachuma:Masitepe osavuta oyeretsera komanso kutsika kwamphamvu kwamagetsi kumadula ndalama zopangira ndi ~ 30%, zomwe zimapereka mwayi wopikisana kwa opanga.

Zotsatira Zamakampani

Kukonzekera kumeneku kumafika panthawi yofunika kwambiri. Ndi kufunikira kwa phenoxyethanol padziko lonse lapansi kukuyembekezeka kukula pa 5.2% CAGR (2023-2030), motsogozedwa ndi zodzoladzola zachilengedwe komanso zachilengedwe, opanga amakumana ndi chikakamizo chotsatira njira zokometsera zachilengedwe. Makampani monga BASF ndi Clariant adayesa kale njira zothandizira zofananira, kupereka malipoti ochepetsa mpweya wa carbon ndi nthawi yopita kumsika. Kuphatikiza apo, kuchulukitsitsa kwa njirayi kumathandizira kupanga kugawikana kwa mayiko, kupangitsa kuti mayendedwe azigawo komanso kuchepetsa utsi wokhudzana ndi kayendedwe ka zinthu.

Zam'tsogolo

Kafukufuku wopitilira amayang'ana pa bio-based ethylene oxide yomwe imachokera kuzinthu zongowonjezwdwa (mwachitsanzo, ethanol ya nzimbe) kuti ipititse patsogolo ntchitoyo. Kuphatikizika ndi nsanja zoyendetsedwa ndi AI zitha kupangitsa kuti zokolola zitheke komanso zolimbikitsa moyo wonse. Kupita patsogolo kotereku kumayika kaphatikizidwe ka phenoxyethanol ngati chitsanzo chakupanga mankhwala okhazikika m'gawo lazodzola.

Mapeto

Kaphatikizidwe kake ka phenoxyethanol kuchokera ku ethylene oxide ndi phenol ndi chitsanzo cha momwe luso laukadaulo lingagwirizanitse magwiridwe antchito a mafakitale ndi kasamalidwe ka chilengedwe. Pothana ndi malire a njira zakale, njira iyi sikuti imangokwaniritsa zomwe msika wamafuta odzola umafuna komanso imayika chizindikiro cha chemistry yobiriwira pakupanga mankhwala apadera. Pamene zokonda za ogula ndi malamulo akupitilira kuika patsogolo kukhazikika, zopambana zoterezi zidzakhala zofunikira kwambiri kuti makampani apite patsogolo.

Nkhaniyi ikuwonetsa kuphatikizika kwa chemistry, uinjiniya, ndi kukhazikika, ndikupereka template yazatsopano zamtsogolo pakupanga zodzikongoletsera.
