Kagwiritsidwe Ntchito
Methanesulfonic acid ndi alkyl sulfonic acid yosavuta kwambiri. Madzi opanda utoto. Osavuta kusungunuka m'madzi, amasungunuka pang'ono mu organic solvents. Acidity yamphamvu yokhala ndi pKa ya -0.6. Sasungunuka m'madzi otentha kapena yankho lotentha la alkaline. Methanesulfonic acid imatha kupangidwa ndi okosijeni wa methyl mercaptan kapena dimethyl disulfide ndi mpweya kapena nitric acid. Itha kukonzedwanso ndi yankho la sodium sulfite ndi dimethyl sulfate m'madzi pa 100 ° C.
Kagwiritsidwe:
Methanesulfonic acid ndi mankhwala ophera tizilombo, omwe amafupikitsidwa kuti MSA, omwe amagwiritsidwa ntchito kwambiri pakupanga ma electroplating ndipo atsimikiziridwa kuti ndi abwino m'malo mwa fluoroboric acid kapena phenolic sulfonic acid. Ndi chinthu chopangira mankhwala ndi mankhwala ophera tizilombo, ndipo chingagwiritsidwenso ntchito ngati chothandizira kuyeretsa madzi, chothandizira kuphimba, chothandizira kuchiza ulusi, chosungunulira, komanso chothandizira kutsuka, kuyeretsa, ndi polymerization reactions.
Kulongedza ndi Kutumiza
250KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ikhoza kuperekedwa ndi nyanja ndi mlengalenga
Malo Osungirako
Methanesulfonic acid ndi mankhwala owononga omwe amafunika njira zodzitetezera panthawi yogwira ntchito, monga kuvala magolovesi oteteza mankhwala, magalasi oteteza, ndi zovala zoteteza.
Mukamagwiritsa ntchito kapena kusunga, sungani kutali ndi zinthu zomwe zimayambitsa moto ndi kutentha kwambiri, ndipo pewani kukhudzana ndi zinthu zowononga ma oxidants.
Mukamagwiritsa ntchito, onetsetsani kuti malo ochitira kafukufuku ali ndi mpweya wabwino ndipo pewani kupuma mpweya wake.
