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

I-Octadecenylsuccinic Anhydride (ODSA) lishishini lokukhanya elisetyenziswa ngokubanzi kwimichiza ecocekileyo yemathiriyeli. Kumzi-mveliso wephepha, isetyenziswa njenge-ejenti yokulinganisa engathathi hlangothi ukuze iphucule kakhulu ukusebenza kokungangeni kwamanzi, amandla okuqina, ukunganyangeki kwe-abrasion, ubumhlophe, ukufihlwa kwephepha kunye nokuphucula imeko yekhemikhali yenkqubo yokwenza iphepha. Ngokwesiqhelo, inkqubo esetyenziswayo kukwenza i-alpha olefins ibe yi-isomerize kwaye emva koko isabele nge-maleic anhydride ukuyivelisa.

Isicelo

1. I-Octadecenyl succinic anhydride (ODSA) yi-ejenti yokulinganisa esebenzayo kakhulu, isetyenziswa ikakhulu kwi-site emulsification saying kumatshini wokusila wephepha. Iqukethe i-olefin skeleton engaxutywanga edityaniswe ne-succinic anhydride, kwaye idla ngokuveliswa ngamanyathelo amabini: okokuqala, i-unsaturated straight-chain okanye i-olefin ye-branched i-isomerized yi-double bond displacement; emva koko, umxube we-isomeri olefin usabela kunye ne-anhydride ye-maleic, kunye ne-ASA imathiriyeli ekrwada ifunyenwe ngokusabela okongeziweyo kunye nokucocwa okuhambelanayo. I-ASA ilulwelo kwiqondo lobushushu begumbi kwaye inokugcinwa kakuhle, okubangelwa kukudityaniswa kwayo kunye neziphumo ze-flocculation, eziphunyezwa ngolawulo lwentlawulo kunye nokudityaniswa kwe-emulsifiers, izizinzi, abakhuthazi kunye nezincedisi zokugcina. Ukuze kuphuculwe ukugcinwa kwe-ASA kwiifibers, i-quaternary ammonium cationic starch, i-polyacrylamide (i-retention aid), i-methylene dithiocyanate (i-preservative) kunye neepolymers ze-cationic eziqukethe i-polyamines zidla ngokusetyenziswa njengee-arhente ezixhasayo. ...
2. Ukongeza, i-octadecenyl succinic anhydride (ODSA) ikwasetyenziswa njengekhemikhali ephakathi kwaye idlala indima ebalulekileyo ekuvelisweni kweekhemikhali. Iimpawu zayo zeekhemikhali ziyasebenza kwaye inokuthatha inxaxheba kwiintlobo ezahlukeneyo zokusabela kweekhemikhali ukuvelisa ezinye iikhemikhali, eziyenza isetyenziswe ngokubanzi kwiindawo ezahlukeneyo zemizi-mveliso2. ...
3. Isishwankathelo, i-octadecenyl succinic anhydride ayisetyenziswanga kuphela njenge-agent yokulinganisa kwishishini lokwenziwa kwephepha, kodwa nanjengeyona ndawo ibalulekileyo phakathi kushishino lweekhemikhali, ebonisa ukusetyenziswa kwayo ngokubanzi nokubaluleka kwayo kwishishini lemichiza.
