Diisopropyl ether

Sifooyinka kiimikada:

Dareere aan midab lahayn, dareere ah oo guban kara oo leh isbeddel dhexdhexaad ah, oo leh ur gaar ah oo ether ah. Waxay samayn kartaa azeotrope oo leh biyo, isopropyl alcohol, acetone, acetonitrile iyo ethanol.

Ujeeddo:

Diisopropyl ether waa dareere wanaagsan oo loogu talagalay saliidaha iyo dufanka xayawaanka, khudaarta iyo macdanta. Waxaa loo isticmaali karaa in nikotiin laga soo saaro tubaakada. Sidoo kale waa dareere wanaagsan oo loogu talagalay shamaca paraffin iyo resin. Warshadaha, diisopropyl ether waxaa badanaa lagu qasaa dareere kale si loogu mariyo alaabada ku salaysan paraffin. Habka nadiifinta saliidda. Sida dareere, waxaa sidoo kale loo isticmaalaa daawooyinka, kiimikooyinka aan qiiqa lahayn, dahaarka iyo nadiifinta rinjiga. Diisopropyl ether waxay leedahay tiro octane ah oo sare iyo sifooyin ka hortagga barafowga waxaana loo isticmaali karaa sidii wakiil isku darka gaaska. Badeecadani si fudud ayay u sameysaa peroxide waxayna qaraxdaa marka la ruxo. Para-benzylaminophenol badanaa waxaa lagu daraa xasiliye ahaan. Saamaynta suuxinta ee diisopropyl ether way ka fudud tahay tan diethyl ether, laakiin muddada suuxdintu way ka dheer tahay.

Habka wax soo saarka Warshadaha ahaan, waxaa laga soo saari karaa wax soo saarka ka soo baxa khamriga isopropyl ee laga soo saaro fuuq-celinta aashitada propylene sulfuric. Propylene waxay la falgashaa aashitada sulfuric si ay u samayso isopropyl hydrosulfate, kaas oo markaa lagu shubo khamriga isopropyl. Inta lagu jiro falcelinta, isopropyl hydrogen sulfate iyo propylene waxay sii wadaan inay ka falceliyaan sameynta diisopropyl sulfate, kaas oo la falgala khamriga isopropyl si uu u sameeyo isopropyl hydrogen sulfate iyo diisopropyl ether. Ka dib falcelinta fuuq-celinta aashitada sulfuric, walxaha Chemicalbook waxaa laga saaraa uumi munaaradda desorption si looga sii daayo khamriga isopropyl iyo diisopropyl ether xalka aashitada. Kadib, iyada oo loo marayo kala-soocidda, diisopropyl ether waxaa marka hore laga helaa dusha sare ee munaaradda. Shaybaarka, isopropyl ether waxaa laga heli karaa iyadoo la fuuq-baxiyo khamriga isopropyl oo leh aashitada sulfuric, ama iyadoo la isticmaalayo hydrogenation isopropyl alcohol iyo acetone. Waxa kale oo lagu samayn karaa isku-darka katalytic ee khamriga isopropyl iyo propylene. Diisopropyl ether waxaa sidoo kale lagu soo saari karaa habka resin exchange ion.
