Octadecenylsuccinic Anhydride CAS 28777-98-2
Octadecenylsuccinic Anhydride (ODSA) ndi mafakitale owala omwe amagwiritsidwa ntchito kwambiri ndi mankhwala opangira mankhwala. M'makampani opanga mapepala, amagwiritsidwa ntchito ngati chosalowerera ndale kuti apititse patsogolo magwiridwe antchito amadzi, kulimba kwamphamvu, kukana ma abrasion, kuyera, kuwala kwa pepala ndikuwongolera chilengedwe chamankhwala popanga mapepala. Nthawi zambiri, njira yomwe imagwiritsidwa ntchito ndikuchotsa ma alpha olefins kenako ndikuchita ndi maleic anhydride kuti apange.

1. Octadecenyl succinic anhydride (ODSA) ndi yotakasuka kwambiri, makamaka yogwiritsidwa ntchito popanga emulsification sizing mu mphero zamapepala. Amakhala ndi mafupa a olefin osatulutsidwa omwe amalumikizidwa ndi succinic anhydride, ndipo nthawi zambiri amapangidwa m'masitepe awiri: choyamba, unsaturated olefin wowongoka kapena nthambi za olefin zimasunthidwa ndi kusamutsidwa kawiri; ndiye, chisakanizo cha isomeric olefin chimachita ndi maleic anhydride, ndipo ASA zopangira zimapezedwa kudzera mukuchita kowonjezera ndi kuyenga kofananira. ASA ndi madzi otentha kutentha ndipo imakhala yosungidwa bwino, zomwe zimachitika chifukwa cha coagulation ndi flocculation zotsatira, zomwe zimatheka kudzera mu lamulo lachiwongola dzanja ndikumanganso ma emulsifiers, stabilizers, olimbikitsa ndi zothandizira posungira. Pofuna kupititsa patsogolo kusungidwa kwa ASA pa ulusi, quaternary ammonium cationic starch, polyacrylamide (retention aid), methylene dithiocyanate (preservative) ndi ma polima a cationic okhala ndi polyamines amagwiritsidwa ntchito ngati othandizira. pa
2. Kuphatikiza apo, octadecenyl succinic anhydride (ODSA) imagwiritsidwanso ntchito ngati mankhwala apakatikati ndipo imagwira ntchito yofunika kwambiri popanga mankhwala. Mankhwala ake akugwira ntchito ndipo amatha kutenga nawo mbali pazochita zosiyanasiyana kuti apange mankhwala ena, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana2. pa
3. Mwachidule, octadecenyl succinic anhydride samangogwiritsidwa ntchito ngati sing agent mumakampani opanga mapepala, komanso ngati gawo lapakati pamakampani opanga mankhwala, kuwonetsa momwe amagwiritsidwira ntchito komanso kufunika kwake mumakampani opanga mankhwala.
