Iyini i-Octadecenylsuccinic Anhydride CAS 28777-98-2?

I-Octadecenylsuccinic Anhydride (ODSA) iyinto eluhlaza esetshenziswa kakhulu embonini elula. Embonini yokwenza amaphepha, isetshenziswa njenge-ejenti yokulinganisa engathathi hlangothi ukuthuthukisa kakhulu ukusebenza okungangeni manzi, amandla okuthamba, ukumelana nokuklwebheka, ubumhlophe, ukungabonakali kwephepha nokuthuthukisa indawo yamakhemikhali yenqubo yokwenza amaphepha. Ngokuvamile, inqubo esetshenziswayo iwuku-isomeraze ama-alpha olefin bese isabela nge-maleic anhydride ukuze ikhiqize.

Isicelo

1. I-Octadecenyl succinic anhydride (ODSA) iyi-ejenti yokulinganisa esabela kakhulu, esetshenziselwa kakhulu ukulinganisa i-emulsification endaweni ezindaweni zokugaya amaphepha. Yakhiwe uhlaka lwe-olefin olungagcwalisiwe oluxhunywe ku-succinic anhydride, futhi ivame ukukhiqizwa ngezinyathelo ezimbili: okokuqala, ama-olefin angagcwalisiwe noma ama-olefin ahlanganisiwe ahlukaniswa ngokufuduka kwezibopho ezimbili; bese kuthi, ingxube ye-olefin ye-isomeric isabela ne-maleic anhydride, bese izinto zokusetshenziswa ze-ASA zitholakala ngokusabela kokwengeza kanye nokuhluzwa okuhambisanayo. I-ASA iwuketshezi ekushiseni kwegumbi futhi inokugcinwa okuhle, okubangelwa yimiphumela yayo yokujiya kanye ne-flocculation, etholakala ngokulawulwa kweshaja kanye nokubopha ama-emulsifiers, iziqinisi, abagqugquzeli kanye nezinsiza zokugcina. Ukuze kuthuthukiswe ukugcinwa kwe-ASA kumafayibha, isitashi se-quaternary ammonium cationic, i-polyacrylamide (usizo lokugcina), i-methylene dithiocyanate (isilondolozi) kanye nama-polymer e-cationic aqukethe ama-polyamines ngokuvamile asetshenziswa njengezinto ezisekelayo. ‌
2. Ngaphezu kwalokho, i-octadecenyl succinic anhydride (ODSA) nayo isetshenziswa njenge-chemical intermediate futhi idlala indima ebalulekile ekukhiqizweni kwamakhemikhali. Izakhiwo zayo zamakhemikhali ziyasebenza futhi ingahlanganyela ezinhlobonhlobo zezindlela zamakhemikhali zokukhiqiza amanye amakhemikhali, okwenza isetshenziswe kabanzi emikhakheni ehlukene yezimboni2.
3. Ngamafuphi, i-octadecenyl succinic anhydride ayisetshenziswa nje kuphela njenge-ejenti yokulinganisa embonini yokwenza amaphepha, kodwa futhi njenge-intermediate ebalulekile embonini yamakhemikhali, ekhombisa ukusetshenziswa kwayo okubanzi kanye nokubaluleka kwayo embonini yamakhemikhali.
