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

I-Octadecenylsuccinic Anhydride (ODSA) sisixhobo esisetyenziswa kakhulu kwishishini lokukhanya esilula. Kwishishini lokwenza iphepha, isetyenziswa njengesixhobo sokulinganisa esingathathi cala ukuphucula kakhulu ukusebenza kokungena kwamanzi, amandla okutsalwa, ukumelana nokukrweleka, ubumhlophe, ukungabonakali kwephepha kunye nokuphucula imeko-bume yeekhemikhali yenkqubo yokwenza iphepha. Ngokwesiqhelo, inkqubo esetyenziswayo kukwenza i-alpha olefins isomereze ize emva koko iphendule nge-maleic anhydride ukuze ivelise.

Isicelo

1. I-Octadecenyl succinic anhydride (ODSA) yiarhente yokulinganisa esabela kakhulu, esetyenziswa kakhulu ekwenzeni ubungakanani be-emulsification kwindawo kwiifektri zamaphepha. Iqulathe iskeleton ye-olefin engagcwaliyo eqhagamshelwe kwi-succinic anhydride, kwaye idla ngokuveliswa ngamanyathelo amabini: okokuqala, ii-olefin ezingagcwaliyo okanye ezinamasebe zixutywa yi-double bond displacement; emva koko, umxube we-olefin ye-isomeric uphendula kwi-maleic anhydride, kwaye izinto eziluhlaza ze-ASA zifunyanwa ngokusabela okongeziweyo kunye nokucocwa okuhambelanayo. I-ASA ilulwelo kubushushu begumbi kwaye inokugcinwa okuhle, okubangelwa kukuqina kwayo kunye nemiphumo ye-flocculation, efezekiswa ngokulawulwa kwetshaja kunye nokudibanisa ii-emulsifiers, izibambisi, izikhuthazi kunye nezixhobo zokugcina. Ukuze kuphuculwe ukugcinwa kwe-ASA kwiifayibha, i-quaternary ammonium cationic starch, i-polyacrylamide (uncedo lokugcina), i-methylene dithiocyanate (isigcini) kunye nee-cationic polymers eziqulathe ii-polyamines zihlala zisetyenziswa njengee-agents ezixhasayo. ‌
2. Ukongeza, i-octadecenyl succinic anhydride (ODSA) ikwasetyenziswa njenge-chemical intermediate kwaye idlala indima ebalulekileyo kwimveliso yeekhemikhali. Iipropati zayo zeekhemikhali ziyasebenza kwaye zinokuthatha inxaxheba kwiindlela ezahlukeneyo zeekhemikhali ukuvelisa ezinye iikhemikhali, nto leyo eyenza ukuba isetyenziswe kakhulu kwiindawo ezahlukeneyo zoshishino.
3. Ngamafutshane, i-octadecenyl succinic anhydride ayisetyenziswa nje kuphela njenge-arhente yokulinganisa kwishishini lokwenza amaphepha, kodwa ikwasetyenziswa njengesixhobo esibalulekileyo kwishishini leekhemikhali, ibonisa ukusetyenziswa kwayo ngokubanzi kunye nokubaluleka kwayo kwishishini leekhemikhali.
