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

I-Octadecenylsuccinic Anhydride (ODSA) iyimboni yokukhanya esetshenziswa kabanzi ngamakhemikhali aluhlaza. Embonini yokwenza iphepha, isetshenziswa njenge-ejenti yokulinganisa engathathi hlangothi ukuze ithuthukise kakhulu ukusebenza okungangeni manzi, amandla aqinile, ukumelana nemihuzuko, ubumhlophe, ukufiphala kwephepha kanye nokuthuthukisa imvelo yamakhemikhali yenqubo yokwenza iphepha. Imvamisa, inqubo esetshenziswayo iwukuba ihlukanise i-alpha olefins bese isabela nge-maleic anhydride ukuyikhiqiza.

Isicelo

1. I-Octadecenyl succinic anhydride (ODSA) iyi-ejenti yokulinganisa esebenza kakhulu, esetshenziswa kakhulu ekufakweni kwe-emulsification ekumshinini wokugaya amaphepha. Iqukethe i-olefin skeleton engagcwalisiwe exhunywe ku-succinic anhydride, futhi ngokuvamile ikhiqizwa ngezinyathelo ezimbili: okokuqala, ama-olefin aqondile angagcwele noma ama-olefin ane-branched ahlukaniswa ngokususwa kwebhondi ephindwe kabili; bese, ingxube ye-olefin ye-isomeri isabela ne-maleic anhydride, futhi impahla eluhlaza ye-ASA itholakala ngokusabela okungeziwe kanye nokucwengisiswa okuhambisanayo. I-ASA iwuketshezi ezingeni lokushisa lasekamelweni futhi inokugcinwa okuhle, okubangelwa ukujiya kwayo kanye nemiphumela ye-flocculation, efinyelelwa ngokulawula ukushaja nokuhlanganisa ama-emulsifiers, ama-stabilizer, abagqugquzeli nezinsiza zokugcina. Ukuze kuthuthukiswe ukugcinwa kwe-ASA kumafayibha, isitashi se-quaternary ammonium cationic, i-polyacrylamide (usizo lokugcina), i-methylene dithiocyanate (i-preservative) kanye nama-polymer cationic aqukethe i-polyamines ngokuvamile asetshenziswa njengama-ejenti asekelayo. .
2. Ngaphezu kwalokho, i-octadecenyl succinic anhydride (ODSA) nayo isetshenziswa njengekhemikhali emaphakathi futhi idlala indima ebalulekile ekukhiqizweni kwamakhemikhali. Izakhiwo zayo zamakhemikhali ziyasebenza futhi zingabamba iqhaza ezinhlobonhlobo zokusabela kwamakhemikhali ukukhiqiza amanye amakhemikhali, okuwenza asetshenziswe kabanzi emikhakheni yezimboni ehlukene2. .
3. Kafushane, i-octadecenyl succinic anhydride ayisetshenziswa nje kuphela njenge-ejenti yokulinganisa embonini yokwenza iphepha, kodwa futhi njengento ebalulekile emaphakathi embonini yamakhemikhali, ebonisa ukusetshenziswa kwayo okubanzi nokubaluleka embonini yamakhemikhali.
