Ukukhiqizwa yezimboni ethylene glycol

Ethylene glycol - kuyinto kancane viscous, oily, uketshezi ayinaphunga. Kuyinto kakhulu oncibilikayo alcohols, amanzi, acetone kanye turpentine. Ethylene glycol luyisisekelo emelana nokubanda enhlanzini yasezindaweni yezimoto nendlu ngoba kwehlisa embundwini for okokuqandisa yamanzi kanye nezixazululo aqueous. Kuvele Eqinisweni ezithakazelisayo wukuthi ngisho uketshezi eqandisiwe akuyona waphulukisa, kuphenduke ice, futhi nje kuba okuxekethile. Ngaphezu kwalokho, izixazululo aqueous of ethylene glycol akusho ukwandisa futhi ngenxa yalokho musa ilimaze amashubhu kanye kurediyetha kule moto.

Le nto has eliphezulu kakhulu hygroscopic, isb ubamba amanzi kusukela imvelo (emoyeni, amagesi ahlukahlukene). Ukukhiqizwa yezimboni ethylene elamiswa ngePhentekoste izitshalo eziningi zamakhemikhali. Kufanele kukhunjulwe ukuthi ketshezi kuyinto enobuthi, nakuba has a ukunambitheka sweet. Ngakho-ke, nokuxhumana kubalulekile ukuba sithathe izinyathelo. Kuzo izinto ube ubuthi hhayi kakhulu futhi zingase zibe ingozi empilweni kuphela ephefumula zabo ezinde. Ethylene glycol - uxhumano nophethiloli. lokuhlala Ephakeme umusi in emoyeni kukhona kuqhume, kodwa inhlanganisela ngamanzi, ethylene glycol ilahlekelwa lezi izakhiwo.

isicelo

Ethylene glycol isetshenziswa emikhakheni ehlukahlukene kanye nezimboni: yezimoto, amakhemikhali, Aerospace, zendwangu, ugesi, uwoyela negesi. Omunye izicelo ebaluleke kakhulu le nto kukhiqizwe coolants futhi emelana nokubanda enhlanzini yasezindaweni. Ngenxa ukufuneka kakhulu ukukhiqizwa yezimboni of ethylene isibe omkhulu. Lo mkhiqizo kungasetshenziswa njengoba kuphela imikhiqizo upende.

Izindlela yokulungiselela ethylene glycol

Inqubo ukulungiswa ketshezi impela eningi, kodwa ukukhiqizwa yezimboni ayilingani konke wabo. Eyodwa yezindlela ethandwa kakhulu kuyinto ukulungiswa ethylene glycol ngokusebenzisa namachibi odlule oksijini khona kulethe esiliva, kulandele hydration okwalandela. Nokho, isidingo namanje elinye iqhinga. Ulungiselela ethylene glycol ngu hydrolysis of ethylene. Kuzo zombili izimo, hydration yokusabela of ethylene oxide kukhiqizwa khona catalysts futhi ashisa ephakeme. Esikhathini izincwadi, kukhona indlela lapho kulungiselelwa ethylene glycol Kwenziwa kanjena amanzi, formaldehyde futhi i-carbon monoxide. Glycolic acid etholwe isinyathelo sokuqala is phansi esterification ukunikeza ester. Khona-ke, it is hydrogenated ukuba ethylene glycol. Le nqubo isetshenziswa e-United States.

Umkhiqizo kwaphumela kuyinto ahlanzekile ngokuphelele, ngoba ngisho ukolweni omncane contaminants zangaphandle kubathinta kabi impahla yayo. Ngokwesibonelo, e khona ethylene glycol lichaza ekwakheni izinto ezifana diethylene glycol futhi polyglycols, kungapheli kwato ezishisayo is kakhulu ziyancipha. Ngakho-ke, kufanele umkhiqizo iphesenti izinga okusezingeni uxhumano zangaphandle lincane. Lokhu kuyiqiniso ikakhulukazi ngokuphathelene compounds kampompi ukuxova umuthi wokugoma kanye aldehydes. ingxenyenamba Mass enkompolo eziyisisekelo kufanele okungenani 99,5%.
