DinonylNaphthalenesulfonic Acid (DNNSA) ine Cas 25322-17-2
Dinonylnaphthalenesulfonic acid kana kuti nhamba yeDNNSACAS ndeye 25322-17-2, rudzi rwemakemikari eorganic. Dinonylnaphthalenesulfonic acid solution ine acidic. Boka resulfonic acid (-SO3h) riri mumorekuru yaro rinogona kupa mapurotoni, richiratidza hunhu hwakafanana hweacids uye rinogona kuita nemabhesi, metal oxides, nezvimwewo.
Dinonylnaphthalenesulfonic acid imushonga we cationic surfactant, unogona kushandiswa semushonga wekuisa machira uye sezvinhu zvekugadzira zvinhu zvinotonhodza (zvakavharwa uye zvisina kuvharwa) zvependi yekubika amino.
| Chitarisiko | Mvura ine viscous yebrown yakasviba |
| Akukosha kwecid(KOH/g) | 60-65 |
| Chikamu(g/cm3) | 0.92-0.96 |
| Kusviba(Tu - makapu 4 e20℃) | ≥masekondi makumi maviri nemana |
| Hunyoro | ≤1.0% |
| Zvinhu zvisingachinji | 50-55% |
DNNSA inogona kushandiswa sechinhu chinobatsira pakuputira, uye inogona kushandiswawo sechinhu chikuru chekugadzira zvinhu zvinotonhodza zvemaamino baking paint. Dinonylnaphthalenesulfonic acid solution yakakodzera masisitimu ependi anodic electrophoretic nekuda kwekusagadzikana kwayo. Mumasisitimu emagetsi anodic, dinonylnaphthalenesulfonic acid solution inotamiswa nekuiswa nekukurumidza, uye inokonzeresa kuporesa kwehydroxyl, carboxyl uye amino functional groups ine alkylated amino resins. Yakakodzerawo masisitimu ekudzivirira solvent uye waterborne kuti ivandudze ngura. Nekuda kwemagetsi ayo akasimba. Saka, DNNSA inonyanya kukodzera kupfapfaidza nemagetsi. Dinonylnaphthalenesulfonic acid DNNSA inoshandiswa kusimbi yecoil, can pendi, automobile pendi, general industrial surface uye primer. Huwandu hwekuwedzera i0.5--2%, dinonylnaphthalenesulfonic acid inogona kuderedza tembiricha yekubika uye kupfupisa nguva yekubika. Nguva yekubika, inovandudza kuomarara uye kuramba kwemakemikari kwefirimu rependi.
Kushanda zvakanaka kwe catalytic
Dinonylnaphthalenesulfonic acid yakakodzera esterification, etherification, condensation reaction (senge synthesis yeplasticizer, resin coating, dzimwe nzira dzechinyakare dzesulfuric acid catalyst dzinogona kuderedza mhedzisiro, kuderedza product acid); Panguva imwe chete, inogona kukonzera cross-linking reaction yezvinhu zvepolymer uye kuwedzera hunhu hwemakanika hwezvinhu.
Kudzivirira ngura zvakanaka uye kudzivirira ngura
Mumvura yemafuta ekuzora, simbi inogadzirwa, Dinonylnaphthalenesulfonic acid inonyungudutsa firimu re compact monomolecular pamusoro pesimbi, yobvisa okisijeni, mvura nechinhu chinoparadza (semuenzaniso, munyu, organic acids). Nguva yekudzivirira ngura yesimbi dzakajairika dzakadai sesimbi, mhangura nearuminiyamu inogona kuwedzerwa ka2 kusvika ka5, uye haizoitirwe makemikari pamusoro pesimbi kuti igadzire zvinhu zvinokuvadza.
Kusagadzikana kwakaderera uye kuramba kupisa kwakanyanya
Mushonga weDinonylnaphthalenesulfonic acid pasi pekupisa kwakajairika kwemvura inonamira, inofashaira zvishoma (> 300 ℃), kana tembiricha yakakwira (senge oiri yeinjini, pendi yekupisa yakakwira) kana ikarasika, inogona kuchengetedza kugadzikana kwebasa kwenguva yakareba.
✅Zviri muDNNSA zvinosvika pamusoro pe55%, zvinova zvakakwirira kupfuura avhareji yemusika ye30% kusvika 50%
✅Rudzi rweCationic rune basa rakawanda pamusoro
✅Zviripo uye nguva pfupi yekutumira zvinhu
✅Hunhu hwacho hwakaenzaniswa nerudzi rweAmerican king1050
Dinonylnaphthalene sulfonic acid CAS 25322-17-2 inotengeswa nevatengi.
