Guhanga udushya twikoranabuhanga: Synthesis yo Kwisiga-Icyiciro PHonoxyhanol kuva Ethyne Oxide na Fhonol

Intangiriro

PhenoxyEthanol, hirya no hino mu kwisiga, yagaragaye icyamamare kubera akamaro kayo irwanya imikurire ya microbial no guhuza n'imikorere y'uruhu. Gakondo yakoresheje unyuze kuri Williamson Ether Synthesiziya ukoresheje Sydroxide nka tatalyst, inzira ihura nibibazo nka Byproduct Gukora, Ingufu zidafite imbaraga, nibidukikije. Iterambere rya vuba muri chimie ya kataleti na green bafunguye inzira nyabagendwa: Imyitwarire itaziguye ya Ethylene okiside ifite isuku, kwisiga-kwisiga-byiciro phenoxyhanol. Iyi masezerano yo guhanga udushya yo gucungura amahame yumwanda utanga umusaruro mu rwego rwo kwemeza birambye, bitesha agaciro, no gukora neza.

INGORANE muburyo busanzwe

Synthesis ya kera ya phenoxyhathanol ikubiyemo imyitwarire ya fenol ifite 2-chloroethanol muburyo bwa alkaline. Mugihe akamaro, ubu buryo buhebire bwa sodium chloride nka ampledict, bisaba intambwe yagutse cyane. Byongeye kandi, ikoreshwa rya chloninater interants zizamura impungenge y'ibidukikije n'umutekano, cyane cyane mu guhuza inganda zo kwisiga zerekeza kuri "Green Chimie". Byongeye kandi, kugenzura ibintu bidahuye akenshi biganisha ku kwanduza nka polyethylene glycol ibikomokaho, bihumura ibicuruzwa ubuziranenge hamwe nubumenyi bushinzwe kugenzura.

Udushya twikoranabuhanga

Ikinyoma kiryamye munzira yintambwe ebyiri za kataletititike zikuraho chrubine reagents hanyuma ukugabanya imyanda:

Ibikorwa bya Epoxide:Eporide oxide, epoxyde yumvikana cyane, ihinduka impeta-ifungura imbere ya fenol. Igitabo gishya gitagira umutsima uhuza umusemburo (urugero, aside ya Zeolite ishyigikiwe na Sulfonic) yorohereza iyi ntambwe yubushyuhe bworoheje (60-80 °, kwirinda ibihe bikomeye.

Guhitamo Guhitamo:Catalistst iyobora reaction kuri phenoxyhathanol ishingaro mugihe uhagarika imyigaragambyo. Sisitemu yo kugenzura uburyo bwo kugenzura, harimo na microreactor ikoranabuhanga, menya ubushyuhe buke hamwe nubuyobozi bwa stochiometric, kugera kuri 95 kubiciro byo guhinduka.

Ibyiza byingenzi byuburyo bushya

Kuramba:Mu gusimbuza ibanziriza ibanziriza eslone hamwe na ethlone okiside, inzira ikuraho imigezi yangiza. Guhurira kwa Catalist bigabanya ibiciro, guhuza ibitego byubukungu byizengurutse.

Ubuziranenge n'umutekano:Kubura intuon ya chloride iremeza kubahiriza amabwiriza yinyongera yo kwisiga (urugero, amabwiriza yo kwihitiramo EU No 1223/2009). Ibicuruzwa byanyuma bihura> 99.5% ubuziranenge, bune cyane kubisaba uruhu.

Imikorere y'ubukungu:Intambwe zoroshye zo kwezwa no gufata ingufu zigabanuka zigura umusaruro na ~ 30%, zitanga inyungu zo guhatanira abayikora.

Inganda

Urushya rugera mugihe cyingenzi. Hamwe na PrenoxyEethal Phonoxyhathal yateraniraga gukura kuri 5.2% Cagr (2023-2030), itwarwa n'ibihe bisanzwe na kama, abakora bahura n'igitutu cyo kwemeza ibidukikije. Amasosiyete nka Basf na Elariant bamaze gusuzuma sisitemu isa na kataletike, raporo yagabanije ibirenge bya karubone hamwe nigihe-cyihuse. Byongeye kandi, uburyo bwo kwerekana uburyo bwo kwegereza abaturage umusaruro, Gushoboza iminyururu yo mu karere no kugabanya imyanyako ijyanye na logistique.

Ibizaza

Ubushakashatsi bukomeje bwibanda kuri etylene ishingiye kuri Ethylene ishingiye ku mutungo ushoborarwaho (urugero, isukari ethanol) kugirango arusheho gutangaza inzira. Kwishyira hamwe hamwe na Ai-Gukuramo Ibikoresho byo Kwegeranya Byagutse bishobora kuzamura umusaruro watanzwe na Catalime Ubuzima. Iterambere nk'iryo phenoxyethanol synthesis nk'icyitegererezo cyo gukora imiti irambye mu rwego rwo kwisiga.

Umwanzuro

Synthesis ya Cataleyhathanol iturutse i Ethylene oxide na fenol byerekana uburyo udushya twikoranabuhanga dushobora guhuza neza inganda hamwe nibisonga byibidukikije. Mugukemura aho ubushobozi bwumushinga, ubu buryo budahuye gusa nibyifuzo byisoko ryibikorikori ariko binashyiraho ibipimo bya chimie yicyatsi mubuvuzi bwihariye bwa chimie. Mugihe ibyo abaguzi n'amabwiriza bikomeje gushyira imbere kuramba, kwiteranya nkibi bizakomeza gukurikizwa niterambere ryinganda.

Iyi ngingo irerekana ihuriro rya chimie, Ubwubatsi, no Kuramba, Gutanga inyandikorugero yo gukurikirane udushya twinshi mukora ibintu byihishe mukora.
