A masana'antu samar da ethylene glycol

Ethylene glycol - shi ne dan kadan da danko sosai, m, odorless ruwa. Yana da matuƙar narkewa a alcohols, ruwa, acetone da turpentine. Ethylene glycol ne dalilin mota maganin daskarewa da kuma iyali tun da shi lowers dokin ga daskarewa ruwa da mai ruwa-ruwa mafita. An ban sha'awa Gaskiyar ita ce, har ma da daskararre ruwa ba warke, juya cikin kankara, da kuma kawai ya zama sako-sako da. Bugu da ƙari, mai ruwa-ruwa mafita ethylene glycol ba fadada sabili da haka ba su lalata da shambura da lagireto a cikin abin hawa.

Wannan abu yana da matukar high hygroscopic, Ina nufin garwaya da ruwa daga yanayi (iska, daban-daban gas). A masana'antu samar da ethylene kafa a dama chemical. Ya kamata a tuna da cewa abu ne mai guba, ko da yake yana da wani zaki da dandano. Saboda haka, hulda da shi wajibi ne ya dauki riƙi shirinku. Nau'i-nau'i daga abubuwa da ba ma high yawan guba da kuma iya dokoki ne da hatsari ga lafiya ne kawai a tsawon inhalation. Ethylene glycol - wani man fetur connection. High yawa na tururi a cikin iska ne m, amma a cakuda da ruwa, ethylene glycol hasarar wadannan kaddarorin.

Ethylene glycol da ake amfani a fannoni daban daban da kuma masana'antu: mota, sunadarai, Aerospace, yadi, lantarki, da man fetur da kuma iskar gas. Daya daga cikin mafi muhimmanci aikace-aikace na wannan abu ne samar da coolants da maganin daskarewa. Saboda da high bukatar masana'antu samar da ethylene ya zama babban. Wannan samfurin za a iya amfani da a matsayin sauran ƙarfi ga Paint kayayyakin.

Hanyar na shirya ethylene glycol

Hanya domin shiri na abu quite mai yawa, amma ga masana'antu samar ba ya shige dukkan su. Daya daga cikin mafi mashahuri hanyoyin shi ne shiri na ethylene glycol ta yin amfani da na karshe hadawan abu da iskar shaka ta oxygen a gaban wata azurfa mai kara kuzari, ya bi ta hanyar m hydration. Duk da haka, bukatar shi ne har yanzu wani dabara. Shiri na ethylene glycol da hydrolysis ethylene. A lokuta biyu, da hydration dauki ethylene oxide samar a gaban catalysts kuma a dagagge zafin jiki. A cikin wallafe-wallafe, akwai kuma wani hanya a wanda shiri na ethylene glycol ne da za'ayi ta maida martani ruwa, formaldehyde da carbon monoxide. Glycolic acid samu a mataki na farko ne hõre esterification ba ester. Sa'an nan, shi ne hydrogenated zuwa ethylene glycol. Wannan dabara da ake amfani a Amurka.

A sakamakon samfur ne sosai tsabta, domin ko kananan yawa na waje abin gurɓatawa adversely rinjayar da kaddarorin. Alal misali, a gaban ethylene glycol a cikin abun da ke ciki na abubuwa irin diethylene glycol da polyglycols, ta thermal kwanciyar hankali da aka rage muhimmanci. Saboda haka, high quality samfurin yawan waje sadarwa ya kamata a rage girmanta. Wannan Gaskiya ne, na magni mahadi da aldehydes. Mass sulusi da murabba'i na asali fili ya kamata a kalla 99,5%.
