I-Phylene Oxide uhlobo lwezinto zokwenziwa ezibalulekile zamakhemikhali kanye nezinto eziphakathi, ezisetshenziswa kabanzi ekukhiqizweni kwama-polytheate polyols, polyerete polyols, ama-polyurethane, ama-polyester, amapulasitiki, ama-surfactants kanye nezinye izimboni. Njengamanje, ukukhiqizwa kwe-appylene oxide kuhlukaniswe izinhlobo ezintathu: ukuhlanganiswa kwamakhemikhali, ukuhlanganiswa kwe-enzyme catalytic kanye nokuvutshelwa kwemvelo. Izindlela ezintathu zinezimpawu zazo kanye nesilinganiso sohlelo lokusebenza. Kuleli phepha, sizohlaziya isimo samanje kanye nentuthuko yentuthuko ye-propylene oxide ukukhiqizwa kobuchwepheshe, ikakhulukazi izici nezinzuzo zezinhlobo ezintathu zezindlela zokukhiqiza, bese uqhathanisa isimo eChina.

Okokuqala, indlela yamakhemikhali ye-Chemical syntow ye-PepyLele Oxide iyindlela yendabuko, enezinzuzo zobuchwepheshe abavuthiwe, inqubo elula kanye nezindleko eziphansi. Inomlando omude namathemba wohlelo lokusebenza olubanzi. Ngaphezu kwalokho, indlela yamakhemikhali ye-Chemical Synthesis nayo ingasetshenziselwa ukukhiqizwa kwezinye izinto ezibalulekile zamakhemikhali kanye nezinto eziphakathi, njenge-oxide ye-ethylele oxide, i-burylene oxide kanye ne-styrene oxide. Kodwa-ke, le ndlela nayo inobunzima obuthile. Isibonelo, i-catalyst esetshenziswe kwinqubo ivame ukuguquguquka futhi iyakhulisa, okuzobangela ukulimala kwemishini kanye nokungcoliswa kwemvelo. Ngaphezu kwalokho, inqubo yokukhiqiza idinga ukusebenzisa amandla amaningi kanye nezinsizakusebenza zamanzi, ezizokhulisa izindleko zokukhiqiza. Ngakho-ke, le ndlela ayilungele ukukhiqizwa okukhulu eChina.

Okwesibili, indlela ye-enzyme catalytic synthesis indlela entsha ethuthukiswe eminyakeni yamuva. Le ndlela isebenzisa ama-enzyme njengama-catalysts ukuguqula i-propelene ibe yi-propelene oxide. Le ndlela inezinzuzo eziningi. Isibonelo, le ndlela inezilinganiso eziphezulu zokuguqula kanye nokukhetha kwe-enzyme catalyst; Inokungcoliswa okuphansi kanye nokusetshenziswa okuncane kwamandla; Kungenziwa ngaphansi kwezimo zokusabela ezimnene; Ingakhiqiza nezinye izinto ezibalulekile zamakhemikhali kanye nama-Intermediates ngokushintsha ama-catalysts. Ngaphezu kwalokho, le ndlela isebenzisa amakhompiyutha angewona angewona anobuthi njenge-solvents yokusabela noma izimo ezingenamahhala zokusebenza okuqhubekayo ngokuncishiswa kwezemvelo. Yize le ndlela inezinzuzo eziningi, kusenezinkinga ezithile ezidinga ukuxazululwa. Isibonelo, intengo ye-enzyme catalyst iphakeme, ezokhulisa izindleko zokukhiqiza; I-enzyme catalyst kulula ukuyisebenzisa noma isebenze inqubo yokusabela; Ngaphezu kwalokho, le ndlela isesesigabeni selebhu esesigabeni samanje. Ngakho-ke, le ndlela idinga ukucwaninga okwengeziwe kanye nentuthuko ukuxazulula lezi zinkinga ngaphambi kokuthi isetshenziswe ekukhiqizweni kwezimboni.

Ekugcineni, indlela yokuvuselelwa kwemvelo nayo iyindlela entsha ethuthukiswe eminyakeni yamuva. Le ndlela isebenzisa ama-microorganisms njengama-catalysts ukuguqula i-propelene ibe yi-propelene oxide. Le ndlela inezinzuzo eziningi. Isibonelo, le ndlela ingasebenzisa izinsiza ezivuselelekayo njengemfucumfucu yezolimo njengezinto zokwakha; Inokungcoliswa okuphansi kanye nokusetshenziswa okuncane kwamandla; Kungenziwa ngaphansi kwezimo zokusabela ezimnene; Ingakhiqiza nezinye izinto ezibalulekile zamakhemikhali kanye ne-Intermediates ngokushintsha ama-microorganisms. Ngaphezu kwalokho, le ndlela isebenzisa amakhompiyutha angewona angewona anobuthi njenge-solvents yokusabela noma izimo ezingenamahhala zokusebenza okuqhubekayo ngokuncishiswa kwezemvelo. Yize le ndlela inezinzuzo eziningi, kusenezinkinga ezithile ezidinga ukuxazululwa. Isibonelo, i-microorganism catalyst idinga ikhethwe futhi ihlolwe; Izinga lokuguqulwa kanye nokukhetha kwe-microorganism catalyst kuphansi; Kudinga ukufundwa futhi ukuthi ungalawula kanjani amapharamitha enqubo ukuqinisekisa ukusebenza okuzinzile nokusebenza kahle kokukhiqiza okuphezulu; Le ndlela ibuye idinga ucwaningo oluthe xaxa kanye nentuthuko ngaphambi kokuthi isetshenziswe esigabeni sokukhiqiza izimboni.

Ekuphetheni, yize indlela ye-Chemical Synthesis inomlando omude kanye namathemba wohlelo lokusebenza olubanzi, inezinkinga ezithile ezinjengokungcoliswa komhlaba kanye nokusetshenziswa kwamandla okuphezulu. I-enzyme catalytic synthesis indlela kanye nendlela yokuvusa ukuvuvukala yizindlela ezintsha ezinokungcoliswa okuphansi kanye nokusetshenziswa kwamandla okuncane, kepha asadinga ucwaningo oluthe xaxa kanye nentuthuko ngaphambi kokuthi zisetshenziswe esigabeni sokukhiqiza izimboni. Ngaphezu kwalokho, ukuze uzuze ukukhiqizwa okuphezulu kwe-oxide e-china ngokuzayo, kufanele siqinise imali ye-R & D kulezi zindlela ukuze zikwazi ukukhiqizwa okungcono kwezomnotho namathemba esicelo ngaphambi kokukhiqizwa okukhulu.
