Kupanga ukadaulo kwa cosmetic-grass phenoxythanol kuchokera ku ethylene oxide ndi phenol

Chiyambi

Phenoxyethanol, yogwiritsiridwa ntchito kwambiri yodzikongoletsa, yakhala yotchuka chifukwa chothandizidwa ndi microbial kukula komanso kugwirizana ndi mawonekedwe ochezeka. Mwamwayi matenda a Williamson ether synthesis pogwiritsa ntchito sodium hydroxide monga chothandizira, njirayi nthawi zambiri imakumana ndi zovuta monga kupangidwa monga mwatsopano, komanso nkhawa zachilengedwe. Kupita patsogolo kwapakuposachedwa kwa chemistry ndi ukadaulo wobiriwira sikunatsegule phazi latsopano: zomwe zimapangitsa Ethylene oxide ndi phenoxythanol. Malingaliro opanga zipatsozi opanga mafakitale pogwiritsa ntchito kukulitsa, kukwiya, komanso kugwiritsa ntchito mtengo.

Zovuta mu Njira Zachilendo

Kaphatikizidwe kameneka ka phenoxyethanol kumaphatikizapo momwe phenol ndi 2-chlororoenol mu milkaline. Ngakhale kuti njirayi imapanga sodium chloride ngati chotupa, chofuna kuyeretsa kwakukulu. Kuphatikiza apo, kugwiritsa ntchito chlorinated Internatives amadzutsa nkhawa zachilengedwe komanso zachitetezo, makamaka mosiyanasiyana ndi kusintha kwa ma primin obiriwira ". Kuphatikiza apo, ulamuliro wosagwirizana womwe umachitika nthawi zambiri umabweretsa zodetsa ngati polyethylene glycol zotumphukira, zomwe zimaletsa kusinthasintha kwa ntchito ndi zowongolera.

Kupanga Mwasayansi

Kutsikirako mabodza mu zinthu ziwiri zomwe zimathetsa mankhwala osokoneza bongo ndipo amachepetsa zinyalala:

Epoxide Kuyambitsa:Ethylene oxide, epyaxide yopindulitsa kwambiri, yomwe imapezeka kutseguka kwa mphero yomwe ilipo pamaso pa phenol. Chatsopano cha nerthergeneous ari acids (mwachitsanzo, a Asuol-Ofinic Othandizira Acid) amathandizira izi pansi pa kutentha pang'ono (60-80 ° C), kupewa mphamvu zamagetsi.

Kusankha Kuyeserera:Chothandizira chimatsogolera zomwe zimachitika pa phenoxythanol polemetsa mbali ya polymerization. Makina otsogola

Ubwino Wofunika Kwambiri

Kukhazikika:Mwa kusinthanitsa chlorinatirs oyambitsa ethylene oxide, njirayo imachotsa mitsinje yoopsa. Kutanthauzira kwa chothandizira kumachepetsa zinthu, kutsatira zinthu zachilengedwe zozungulira.

Kuyera ndi Chitetezo:Kusowa kwa ma ayoni a chloride kumawonekera kutsatira malamulo osokoneza bongo (mwachitsanzo, EU zodzikongoletsera za EU. 1223/2009). Zogulitsa zomaliza zimakumana> 99.5% zoyera, zotsutsa zofuna za skican.

Kuthandiza Kwachuma:Njira zoyenga zoyenga bwino ndi mphamvu zotsika zomwe zimafuna kudula mtengo ndi ~ 30%, kupereka zabwino zodyera.

Zotsatira za Makampani

Kupanga kumeneku kumafika pompopompo. Pokhala ndi zochitika zapadziko lonse kwa phenoxythanol yomwe ikuwonetsedwa kuti ikule bwino (202% CAGR (2022-2030), omwe amayendetsedwa ndi zodzikongoletsera zachilengedwe komanso zachilengedwe zimapanikizika kuti mutenge machitidwe ochezeka a Eco-ochezeka. Makampani monga Basf ndi Clariant ayendetsa kale ma jakiya, malipoti ochepetsa mapazi a kaboni komanso msika wa nthawi yayitali. Kuphatikiza apo, kufooka kwa njirayo kumathandizira maunyolo ophatikizika, omwe amathandizira maunyolo apadera komanso kuchepetsa mpweya wokhudzana ndi mapulogalamu.

Zoyembekeza zamtsogolo

Kafukufuku wopitilira akuyang'ana pa Ethylene wophatikizidwa ndi ma oxide omwe achokera ku zinthu zokonzanso (mwachitsanzo, nzimbe za ethanol) kuti zitheke. Kuphatikiza ndi nsanja ya AI-Drimimition Kukonzanso kumatha kukulitsa kupereka zokolola komanso zothandizira moyo wonse. Kupita patsogolo kotereku kwa phenoxythanol synthesis ngati chitsanzo kwa kupanga kosinthika kwa mankhwala odzikongoletsa.

Mapeto

Kaphatikizidwe ka mankhwala a phenoxythanol kuchokera ku ethyleenol kuchokera ku ethyleehnol oxide ndi phenolol amalimbikitsa momwe kufulumira kwa ukadaulo kumagwirira ntchito zamafakitale ndi utsogoleri wa chilengedwe. Pothana ndi zofooka za cholembera, njira imeneyi siyimangomaliza zofuna za zodzikongoletsera zodzikongoletsera komanso zimapangitsanso chizindikiro cha umagwirira wobiriwira m'makanema. Monga zokonda ndi magwiridwe antchito akupitilizabe kuyikapobe, zisangalalo zoterezi zidzakhalabe patsogolo pazinthu zamakampani.

Nkhaniyi ikuwonetsa kulumikizana kwa chemistry, upangiri, komanso kukhazikika, kupereka template yazomwe zimapangidwa mkati mwa zodzikongoletsera.
