Octadecenylsuccinic Anhydride CAS 28777-98-2
Octadecenylsuccinic Anhydride (ODSA) ndi mankhwala opangidwa ndi mankhwala opepuka omwe amagwiritsidwa ntchito kwambiri. Mu makampani opanga mapepala, amagwiritsidwa ntchito ngati chinthu choletsa kukula kwa zinthu zosalowa madzi, mphamvu yokoka, kukana kukwawa, kuyera, kutseguka kwa pepala ndikukonzanso malo opangira mankhwala. Nthawi zambiri, njira yomwe imagwiritsidwa ntchito ndi isomerize alpha olefins kenako nkuchita ndi maleic anhydride kuti ipange.

1. Octadecenyl succinic anhydride (ODSA) ndi mankhwala ochepetsa mphamvu ya maselo, omwe amagwiritsidwa ntchito makamaka pokonza kukula kwa emulsification m'mafakitale a mapepala. Amapangidwa ndi mafupa a olefin osakhuta omwe amalumikizidwa ndi succinic anhydride, ndipo nthawi zambiri amapangidwa m'magawo awiri: choyamba, ma olefin osakhuta kapena nthambi amasinthidwa ndi kusunthika kwa ma bond awiri; kenako, chisakanizo cha isomeric olefin chimagwirizana ndi maleic anhydride, ndipo zinthu zopangira za ASA zimapezeka kudzera mu reaction yowonjezera ndi kuyenga kofanana. ASA ndi yamadzimadzi kutentha kwa chipinda ndipo imakhala ndi kusunga bwino, komwe kumachitika chifukwa cha kuuma kwake ndi zotsatira zake, zomwe zimachitika kudzera mu regulation charge ndi bridging ya emulsifiers, stabilizers, promoters ndi retention aids. Pofuna kuwonjezera kusunga kwa ASA pa ulusi, quaternary ammonium cationic starch, polyacrylamide (retention aid), methylene dithiocyanate (preservative) ndi ma cationic polymers okhala ndi polyamines nthawi zambiri amagwiritsidwa ntchito ngati othandizira.
2. Kuphatikiza apo, octadecenyl succinic anhydride (ODSA) imagwiritsidwanso ntchito ngati mankhwala osakaniza ndipo imagwira ntchito yofunika kwambiri popanga mankhwala. Makhalidwe ake a mankhwala amagwira ntchito ndipo amatha kutenga nawo mbali muzochita zosiyanasiyana za mankhwala kuti apange mankhwala ena, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri m'magawo osiyanasiyana amafakitale.
3. Mwachidule, octadecenyl succinic anhydride siigwiritsidwa ntchito kokha ngati chinthu choyezera kukula mumakampani opanga mapepala, komanso ngati chinthu chofunikira kwambiri pakati pamakampani opanga mankhwala, kusonyeza kuti imagwiritsidwa ntchito kwambiri komanso kufunika kwake mumakampani opanga mankhwala.
