Ukuveliswa industrial ethylene ethers

Ethylene ethers - yinto viscous kancinane, olunamafutha ulwelo, esha. Kuyinto ezinyibilikayo kakhulu alkoholi, amanzi, acetone kunye turpentine. Ethylene ethers sisiseko zinendlela izithuthi kunye nendlu ukususela oko lihlisa zokuthethelela qhwa amanzi kunye nezisombululo zolwelo. An into umdla kukuba nkqu ulwelo ekhenkcezisiweyo akukho asinyangeki, ajike abe ngumkhenkce, kwaye nje uba evakalala. Ngaphezu koko, izisombululo zolwelo ethylene ethers akuthethi ukwandisa kwaye ke ngoko zenze umonakalo tyhubhu kwi radiator kwisithuthi.

Le nto iye phezulu kakhulu hygroscopic, ngamanye sitsala amanzi avela kokusingqongileyo (umoya, iigesi ezahlukeneyo). Ukuveliswa industrial ethylene esekwe kwi izityalo ezininzi chemical. Kufuneka kukhunjulwe ukuba ubuncwane yityhefu, noxa kukho incasa elithozamisayo. Ngoko ke, intsebenziswano kunye nayo kuyimfuneko ukuba athathe amanyathelo. Zomdlalo wePurble kwezinto babe zinetyhefu hayi eliphezulu kakhulu kwaye zenze ingozi empilweni kuphela inhalation wabo ixesha elide. Ethylene ethers - uqhagamshelwano amafutha. High lamanani umphunga emoyeni izinto ezinokugqabhuka, kodwa umxube ngamanzi, ethylene ethers ulahlekelwa ezi propati.

isicelo

Ethylene ethers isetyenziswa kwiinkalo ezahlukeneyo kunye namashishini: Automotive, imichiza, aerospace, elukiweyo, umbane, oyile negesi. Enye izicelo ezibalulekileyo kwale nto ukuveliswa coolants kunye nokubanda. Ngenxa yemfuneko enkulu kakhulu kwimveliso woshishino ethylene iye yaba kakhulu. Le mveliso zingasetyenziswa njenge kuphela iimveliso yepeyinti.

Iindlela zokulungiselela ethylene ethers

Inkqubo yokulungisa ukwimo kakhulu eninzi, kodwa imveliso kwimizi awulungelanga yonke kubo. Enye yezona ndlela kakhulu ethandwayo ukulungiselela ethylene ethers ngokusebenzisa igcwala yokugqibela yi oksijini phambi ngumnxibelelanisi yesilivere, kulandele ukuxovwa elandelayo. Noko ke, abafunwayo enye indlela. Ukulungiswa ethylene ethers ngu haydrolisis ethylene. Kuzo zombini ezi meko, basabela ukuxovwa ethylene oxide eveliswa phambi ehlanganisa kunye kwiqondo lobushushu ephakamileyo. Kule ncwadi, kukho kwakhona indlela apho ekulungiseleleni ethylene ethers ikhutshwa phandle ngokuhlanganisa emanzini, formaldehyde kunye carbon monoxide. Glycolic acid afunyenwe kwi inyathelo lokuqala ufakwa esterification ukunika Ester. Emva koko, ke hydrogenated ukuya ethylene ethers. Le ndlela isetyenziswa eUnited States.

Le mveliso eliphuma ecocekileyo ngokupheleleyo, kuba izixa ezincinane ezingcolisa yangaphandle kuchaphazela iimpawu zayo. Ngokomzekelo, phambi ethylene ethers kuhlanganiselo izinto ezifana diethylene ethers kunye polyglycols, ukuzinza kwalo thermal yehliswe kakhulu. Ngoko ke, uxhulumaniso yangaphandle ipesenti imveliso ekumgangatho ophezulu kufuneka kuncitshiswe. Oku kuyinyaniso ngokukodwa iikhompawundi ikhlorini kunye aldehydes. iqhezu Mass ye umchiza esisiseko kufuneka ubuncinane 99,5%.
