ipropylene oxideluhlobo lwemathiriyeli ekrwada yekhemikhali ebalulekileyo kwaye ephakathi.Isetyenziswa kakhulu ekudibaneni kweepolyether polyols, i-polyester polyols, i-polyurethane, i-polyether amine, njl., kwaye yinto ebalulekileyo ekrwada yokulungiswa kwe-polyester polyols, eyona nxalenye ebalulekileyo ye-polyurethane ephezulu.Ipropylene oxide iphinda isetyenziswe njengento ekrwada yokulungiswa kwezinto ezahlukeneyo ze-surfactants, iziyobisi, iikhemikhali zezolimo, njl., kwaye yenye yezinto ezibalulekileyo kwishishini lemichiza.

Ipropylene oxide iveliswa yi-oxidation yepropylene ene-catalyst.Ipropylene yempahla ekrwada ixutywe nomoya ocinezelekileyo kwaye emva koko idluliselwe kwi-reactor ezaliswe yi-catalyst.Ubushushu bokusabela ngokuqhelekileyo yi-200-300 DEG C, kwaye uxinzelelo lu malunga ne-1000 kPa.Imveliso yokusabela ngumxube oqukethe i-propylene oxide, i-carbon dioxide, i-carbon monoxide, amanzi kunye nezinye iikhompawundi.I-catalyst esetyenziswe kule mpendulo yinguqu yesinyithi ye-oxide catalyst, njenge-catalyst yesilivere ye-oxide, i-chromium oxide catalyst, njl.Ukongezelela, i-catalyst ngokwayo iya kucinywa ngexesha lokuphendula, ngoko kufuneka ihlaziywe okanye itshintshwe rhoqo.

Ukwahlula kunye nokucocwa kwepropylene oxide kumxube wokuphendula ngamanyathelo abaluleke kakhulu kwinkqubo yokulungiselela.Inkqubo yokwahlula ngokubanzi ibandakanya ukuhlamba amanzi, i-distillation kunye namanye amanyathelo.Okokuqala, umxube wokuphendula uhlanjwa ngamanzi ukuze ususe amacandelo aphantsi abilayo afana nepropylene engaphendulwanga kunye ne-carbon monoxide.Emva koko, umxube we-distilled ukwahlula i-propylene oxide kwezinye izinto ezibilisa kakhulu.Ukuze ufumane i-high-purity propylene oxide, amanyathelo angaphezulu okuhlanjululwa njenge-adsorption okanye i-extraction ingafuneka.

Ngokuqhelekileyo, ukulungiswa kwepropylene oxide yinkqubo enzima, efuna amanyathelo amaninzi kunye nokusetyenziswa kwamandla aphezulu.Ngoko ke, ukwenzela ukunciphisa iindleko kunye neempembelelo zokusingqongileyo zale nkqubo, kuyimfuneko ukuqhubeka nokuphucula iteknoloji kunye nezixhobo zenkqubo.Okwangoku, uphando kwiinkqubo ezintsha zokulungiselela i-propylene oxide igxile kakhulu kwiinkqubo ezihambelana nokusingqongileyo kunye nokusetyenziswa kwamandla aphantsi kunye nokusebenza kakuhle okuphezulu, njenge-catalytic oxidation usebenzisa i-oxygen ye-molecular njenge-oxidant, inkqubo ye-oxidation ye-microwave, inkqubo ye-oxidation ephezulu, njl. , uphando kwii-catalysts ezintsha kunye neendlela ezintsha zokuhlukana nazo zibaluleke kakhulu ekuphuculeni isivuno kunye nokucoceka kwepropylene oxide kunye nokunciphisa iindleko zokuvelisa.
