1,3-Butadiene / CAS 106-99-0

Isticmaalka

Waxaa loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay caagga synthetic-ka, resin synthetic-ka, fiber-ka synthetic-ka, balaastikada, rinjiga latex-ka, iwm. Butadiene waa walaxda ugu weyn ee ceeriin ah ee lagu soo saaro caagga synthetic-ka (caag styrene-butadiene, caag cis-polybutadiene, caag nitrile-butadiene, caag chloroprene). Iyadoo la horumarinayo balaastikada styrene, iyadoo la isku darayo styrene iyo butadiene, resins kala duwan oo leh codsiyo ballaaran (sida resin ABS, resin SBS, resin BS, resin MBS) ayaa la soo saaraa, taasoo ka dhigaysa butadiene inay si tartiib tartiib ah u qabsato boos muhiim ah oo ku jira wax soo saarka resin-ka. Intaa waxaa dheer, butadiene waxaa sidoo kale loo isticmaalaa soo saarista ethylidene norborne (monomer-ka saddexaad ee caagga ethylene-propylene), 1,4-butanediol (balaastigga injineernimada), adiponitrile (monomer-ka naylon 66), sulfolane, anthraquinone, tetrahydrofuran, iwm. Sidaa darteed, sidoo kale waa walax muhiim ah oo kiimiko ceeriin ah oo aasaasi ah. Butadiene sidoo kale waxay leedahay codsiyo badan oo ku saabsan soo saarista kiimikooyinka fiican. Kiimikooyinka fiican ee loo diyaariyey iyadoo loo adeegsanayo butadiene oo ah walxo cayriin ah waxaa inta badan ka mid ah dhinacyada soo socda: (1) Waxay martaa falgal Diels-Alder ah oo leh iskudhisyo dieneophile oo aan lahayn elektrooni si loo soo saaro anthraquinone, waxyaabaha ka soo baxana waa kuwo muhiim u ah dheeha, fungicides, iyo cayayaanka. (2) Waxay la falgashaa maleic anhydride (oo loo soo gaabiyo maleic anhydride) ka dibna way isku ururtaa si ay u soo saarto tetrahydrophthalic anhydride, kaas oo loo isticmaali karo sidii wakiil bogsiin iyo balaastiig u ah resins polyester iyo resins epoxy. Marka tetrahydrophthalic anhydride si dheeraad ah loogu oksaydhiyo nitric acid, butane tetracarboxylic acid ayaa la heli karaa, kaas oo ah walxo cayriin ah oo loogu talagalay soo saarista rinjiyada biyaha ku milma. Sidoo kale, marka tetrahydrophthalic anhydride la hydrogenated si loo helo hexahydrophthalic anhydride, waxaa loo isticmaali karaa sidii wakiil bogsiin ah resins epoxy. (3) Waxay la falgashaa sulfur dioxide si ay u samayso sulfolene, ka dibna waxaa loo sameeyaa xal biyo ah oo lagu shubo hydrogen iyadoo la joogo kaalshiyam nikkel ah oo qalfoof ah si loo soo saaro sulfolane, kaas oo ah dareere xulasho ah oo loogu talagalay soo saarista haydarojiin udgoon. Isku darka sulfolane iyo diisopropanolamine ayaa loo isticmaali karaa in lagu saaro gaaska kaarboon laba ogsaydh. (4) Falcelinta telomerization-ka toosan ee butadiene waa mid si weyn loo isticmaalo warshadaha. Ka dib marka la kala diro, waxaa la helaa olefin silsilad toosan oo siddeed-kaarboon ah, ka dib marka la kariyo aldehyde iyo hydrogenation, nonanol ayaa la helaa, kaas oo leh codsiyo muhiim ah oo ku saabsan isku-darka udgoonka macmal ah, surfactants, iyo waxyaabaha lagu daro saliidaha. Iyadoo la adeegsanayo isku-dhafka kobalt sida kaalshiyam, dimer-keeda, trimer-keeda, iyo tetramer-keeda dhammaantood waa walxo cayriin ah oo loogu talagalay isku-darka khamriga sare iyo musks-ka macrocyclic. Waa mid ku milma alcohols iyo ethers, waxaana sidoo kale lagu milmi karaa acetone, benzene, dichloroethane, amyl acetate, furfural, iyo xalka cuprammonium acetate. Waa mid aan ku milmi karin biyaha.
