99.9% nadiifinta sare ee Propylene Oxide monomer

Gaar ahaan: 160kg / durbaan

Propylene Oxide, oo sida badan loo soo gaabiyo PO sidoo kalena loo yaqaano 1,2-epoxypropane ama methyloxirane, waa dareere aan midab lahayn, kacsan, aad u ololaya oo leh sifo macaan, ur ether u eg. Alaabtayada qaaliga ah waxay ku gaadhaan nadiifnimo gaar ah 99.9%, hubinta waxqabadka la isku halayn karo ee wax soo saarka polyeter polyol, soosaarka propylene glycol, iyo codsiyada isku-dhafka kiimikada warshadaha ee kaladuwan.

Epoxide-ka asymmetric-ka ugu fudud, propylene oxide waxa uu leeyahay giraan wareeg ah oo saddex xubnood ka kooban oo aad u cidhiidhi ah kaas oo siinaya falcelis gaar ah xagga nucleophiles iyo acids. Cadaadiskan giraanta ah (qiyaastii 114 kJ/mol) ayaa kaxeeya falcelin-furitaan oo hufan oo ku jira xaalado khafiif ah, taasoo ka dhigaysa PO mid ka mid ah dhismayaasha ugu waxtarka badan ee kiimikada dabiiciga ah ee warshadaha. Joogitaanka beddelka methyl ee ku dheggan giraanta epoxide waxay soo bandhigaysaa regioselectivity ee weerarka nucleophilic, taas oo awood u siinaysa isku-darka kontoroolka ee kala duwanaansho kala duwan oo leh astaamo gaar ah oo stereochemical iyo qaabdhismeed.

Warshadaha poliurethaneku waxay matalaan qaybta codsiga ee propylene oxide, halkaas oo ay u adeegto quudinta aasaasiga ah ee soo saarida polyeter-ka. Iyada oo loo marayo polymerization giraanta furitaanka saldhigga-catalyzed, PO waxay samaysaa silsilado polyoxypropylene glycol ah oo leh miisaanyo kelli ah oo la kontaroolay iyo hawlqabadyo, kuwaas oo ka dib la falgala diisocyanates si ay u abuuraan xumbo polyurethane dabacsan oo adag, elastomers, dahaarka, iyo dhejisyada. Qalabkani waxa uu taageeraa dhismaha, baabuurta, alaabta guriga, iyo warshadaha dahaarka ee aduunka oo dhan. Darajada nadiifka sare waxay hubisaa in tirooyinka hydroxyl joogto ah iyo heerar hoose oo unsaturation ah oo muhiim u ah waxqabadka poliurethane.

Soo saarista propylene glycol, PO waxa ay martaa aashito ama hydrolysis sal-catalyzed si ay u samayso propylene glycol (PG), kiimiko qiimo leh oo loo isticmaalo resins polyester-ka aan saturated, hababka antifreeze, daawooyinka, qurxinta, iyo codsiyada cuntada. Waxyaabaha dheeraadka ah waxaa ka mid ah propylene glycol ethers oo loogu talagalay dahaarka iyo alaabta nadiifinta, isopropanolamines ee daawaynta gaaska iyo surfactants, iyo kaydka saliidaha synthetic.

99.9% propylene oxide saafi ah waxay la kulantaa qeexitaanno adag oo loogu talagalay aldehyde hooseeya iyo maadada acetaldehyde, qoyaanka ugu yar, iyo aashitada la xakameeyey, hubinta kinetics polymerization la isku halayn karo iyo tayada wax soo saarka ee soosaarayaasha polyol, soosaarayaasha glycol, iyo shirkadaha kiimikada gaarka ah ee u baahan monomer epoxide-ga sare ee dalabka codsiyada warshadaha.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
