Ukusetyenziswa
I-Methanesulfonic acid yeyona alkyl sulfonic acid ilula. Ulwelo olungenambala. Kulula ukunyibilika emanzini, lunyibilika kancinci kwi-organic solvents. I-acidity enamandla ene-pKa ye -0.6. Ayifakwanga emanzini ashushu okanye kwisisombululo se-alkaline esishushu. I-Methanesulfonic acid inokwenziwa yi-oxidation ye-methyl mercaptan okanye i-dimethyl disulfide ene-oxygen okanye i-nitric acid. Ingalungiswa nangesisombululo se-sodium sulfite kunye ne-dimethyl sulfate emanzini kwi-100 ° C.
Ukusetyenziswa:
I-Methanesulfonic acid sisithako sekhemikhali esibangela ukonakala, esifinyeziweyo njenge-MSA, esinamathuba amaninzi okusetyenziswa kwicandelo le-electroplating kwaye sibonakaliswe njengesithako esilungileyo endaweni ye-fluoroboric acid okanye i-phenolic sulfonic acid. Sisixhobo esiluhlaza samayeza kunye nezibulali-zinambuzane, kwaye singasetyenziswa njenge-arhente yokudambisa amanzi emzimbeni, i-coating curing promoter, i-fiber treatment agent, i-solvent, kunye ne-catalyst yokuhlamba, i-esterification, kunye neempendulo ze-polymerization.
Ukupakishwa kunye nokuthunyelwa
250KG/Idrama okanye ngokweemfuno zomthengi.
Ingahanjiswa ngolwandle nangomoya
Indawo yokugcina izinto
I-Methanesulfonic acid yikhemikhali ebangela ukubola efuna amanyathelo okhuseleko ngexesha lokusebenza, njengokunxiba iiglavu zokukhusela iikhemikhali, iiglasi zokhuseleko, kunye neempahla zokukhusela.
Xa usebenzisa okanye ugcina, yigcine kude nemithombo yomlilo kunye namaqondo obushushu aphezulu, kwaye uphephe ukudibana nee-oxidants.
Xa usebenzisa, qinisekisa ukuba indawo yokusebenzela ingenisa umoya kakuhle kwaye uphephe ukuphefumla umphunga wayo.
