Sulfoisophthalic Acid Monosodium Salt CAS 6362-79-4
5-Sulfoisophthalic acid monosodium salt (CAS 6362-79-4, dzina la Chingerezi: 5-sulfoisophthalic acid monosodium (mchere) ndi chinthu chofunikira kwambiri chopangidwa ndi organic, chomwe chimachokera ku sulfonated modified aromatic dicarboxylic acid derivatives. Kapangidwe kake ka molekyulu kamachokera ku isophthalic acid ngati gulu lalikulu, ndi gulu la sulfonic acid (-SO₃H) lomwe limayikidwa pamalo 5 a benzene ring ndikupanga mchere wokhala ndi sodium.
Poganizira za mphamvu zakuthupi ndi zamankhwala, mchere wa monosodium wa 5-Sulfoisophthalic acid nthawi zambiri umawoneka ngati ufa woyera, wokhala ndi malo osungunuka a 373℃. Pa 20℃, kuchuluka kwake ndi 1.87, ndipo umasungunuka bwino m'madzi (380g/L). Pa 20℃, acidity coefficient yake (pKa) ndi 4.1, ndipo pa 23℃, LogP yake ndi -1.7. Ponseponse. Sodium m-5-sulfonate ndi yokhazikika ndipo imasungunuka mosavuta m'madzi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'madzi.

1. Munda wa zipangizo za polima
Mchere wa 5-Sulfoisophthalic acid monosodium umagwiritsidwa ntchito ngati copolymer monomer popanga "modified polyester": copolymerized ndi terephthalic acid ndi ethylene glycol, ndipo magulu a sodium sulfonate amayambitsidwa kuti akonze hydrophilicity ndi dyeing ya polyester, yomwe imagwiritsidwa ntchito popanga ulusi wa polyester wosavuta kupakidwa utoto ndi zokutira za polyester zochokera m'madzi.
Kukonzekera "ion exchange resin": Magulu a Carboxyl ndi magulu a sodium sulfonate angagwiritsidwe ntchito ngati magulu osinthira ma ion popanga ma resins ofewetsa madzi ndi ma heavy metal ion adsorption.
2. Malo osindikizira ndi kupaka utoto nsalu
Monga "chothandizira kulinganiza": Popaka utoto wa ulusi wopangidwa monga polyester ndi nayiloni, kuwonjezera sodium isophthalic acid 5-sulfonate kungathandize kuwongolera kuchuluka kwa utoto womwe umabwera, kupewa utoto wosagwirizana, ndikuwonjezera kufanana ndi kulimba kwa utoto wa nsalu.
3. Malo ophikira ndi zomatira.
Pa "zophimba zochokera m'madzi": Monga chowonjezera chogwira ntchito, mchere wa 5-Sulfoisophthalic acid monosodium umathandizira kufalikira ndi kukana madzi kwa chophimbacho, umachepetsa kugawanika kwa chophimbacho, komanso umalimbitsa kumamatirana pakati pa chophimbacho ndi gawo lapansi.
"Gulu lopangidwa ndi madzi" losinthidwa: Lopangidwa ndi acrylate, mchere wa 5-Sulfoisophthalic acid monosodium umathandiza kuti guluu likhale lolimba komanso losasinthasintha, loyenera kugwiritsidwa ntchito pazinthu zomangira monga matabwa ndi pulasitiki.
