Octadecenylsuccinic Anhydride CAS 28777-98-2

1. Octadecenyl succinic anhydride (ODSA) ke sesebelisoa se sebetsang haholo sa boholo, se sebelisoang haholo bakeng sa boholo ba emulsification sebakeng seo liindastering tsa pampiri. E entsoe ka masapo a olefin a sa tlalang a hokahantsoeng le succinic anhydride, 'me hangata e hlahisoa ka mehato e 'meli: ea pele, li-olefin tse sa tlalang tse otlolohileng kapa tse nang le makala li isomerized ka ho falla ha maqhama a mabeli; ebe, motsoako oa olefin oa isomer o arabela le maleic anhydride, 'me thepa e tala ea ASA e fumanoa ka karabelo ea ho eketsa le ho hloekisa ho tsamaellanang. ASA ke metsi mochesong oa kamore 'me e na le poloko e ntle, e leng se bakoang ke litlamorao tsa eona tsa ho kopana le ho flocculation, tse fihlellehang ka taolo ea tjhaja le ho koala li-emulsifier, li-stabilizer, li-promoter le lithuso tsa ho boloka. E le ho ntlafatsa poloko ea ASA holim'a likhoele, quaternary ammonium cationic starch, polyacrylamide (thuso ea ho boloka), methylene dithiocyanate (preservative) le li-polymer tsa cationic tse nang le li-polyamine hangata li sebelisoa e le li-agent tse tšehetsang. ‌
2. Ho phaella moo, octadecenyl succinic anhydride (ODSA) e boetse e sebediswa e le mokedikedi wa dikhemikhale mme e bapala karolo ya bohlokwa tlhahisong ya dikhemikhale. Dithoto tsa yona tsa dikhemikhale di a sebetsa mme e ka nka karolo diphetohong tse fapaneng tsa dikhemikhale ho hlahisa dikhemikhale tse ding, e leng se etsang hore e sebediswe haholo masimong a fapaneng a diindasteri.
3. Ka bokhutšoanyane, octadecenyl succinic anhydride ha e sebelisoe feela e le moemeli oa boholo indastering ea ho etsa pampiri, empa hape e le setsi sa bohlokoa indastering ea lik'hemik'hale, e bontšang ts'ebeliso ea eona e pharaletseng le bohlokoa indastering ea lik'hemik'hale.
