Octadecenylsuccinic Anhydride CAS 28777-98-2
Ko te Octadecenylsuccinic Anhydride (ODSA) he rauemi matū pai e whakamahia whānuitia ana i roto i te umanga māmā. I roto i te umanga hanga pepa, ka whakamahia hei taputapu rahi koretake hei whakapai ake i te mahi ātete wai, te kaha kume, te ātete ki te pakū, te mā, te mārama o te pepa, me te whakapai ake i te taiao matū o te tukanga hanga pepa. Ko te tikanga, ko te tukanga e whakamahia ana ko te whakawehewehe i ngā alpha olefins, kātahi ka tauhohe ki te maleic anhydride hei whakaputa.

1. Ko te Octadecenyl succinic anhydride (ODSA) he matū tauhohe rawa, e whakamahia ana mō te whakapūtanga i roto i ngā mira pepa. Kei roto i tēnei he angaanga olefin kāore i te mākū e hono ana ki te succinic anhydride, ā, e rua ngā taahiraa e hangaia ana: tuatahi, ka whakapūtangahia ngā olefin mekameka tika, peka rānei kāore i te mākū mā te nekehanga hononga takirua; kātahi ka tauhohe te ranunga olefin isomeric ki te maleic anhydride, ā, ka whiwhihia te rauemi mata ASA mā te tauhohenga tāpiri me te whakamahine e rite ana. He wai te ASA i te pāmahana rūma, ā, he pai te pupuri, nā ōna pānga whakapūtanga me te flocculation, e tutukihia ana mā te whakahaere utu me te hononga o ngā emulsifier, ngā whakaū, ngā kaiwhakatairanga me ngā āwhina pupuri. Hei whakarei ake i te pupuri o te ASA ki runga i ngā muka, ko te māngaro cationic ammonium quaternary, te polyacrylamide (āwhina pupuri), te methylene dithiocyanate (kaitiaki) me ngā polymer cationic kei roto ngā polyamines e whakamahia ana hei kaihoko tautoko.
2. Hei tāpiritanga, ka whakamahia hoki te octadecenyl succinic anhydride (ODSA) hei takawaenga matū, ā, he mea nui tana mahi i roto i te hanga matū. He kaha te mahi a ōna āhuatanga matū, ā, ka taea e ia te whai wāhi ki ngā momo tauhohenga matū hei whakaputa i ētahi atu matū, ā, nā reira i whānuitia ai te whakamahinga i roto i ngā momo mara ahumahi rerekē2.
3. Hei whakarāpopototanga, ehara i te mea ka whakamahia noa te octadecenyl succinic anhydride hei taputapu ine i roto i te umanga hanga pepa, engari hei takawaenga nui hoki i roto i te umanga matū, e whakaatu ana i tōna whakamahinga whānui me te hiranga i roto i te umanga matū.
