Ukusetshenziswa
I-Methanesulfonic acid iyi-alkyl sulfonic acid elula kakhulu. I-liquid engenambala. Kulula ukuyincibilikisa emanzini, incibilika kancane ezinyibilikisini eziphilayo. I-asidi enamandla ene-pKa engu--0.6. Ayifakwanga emanzini ashisayo noma esixazululweni se-alkaline esishisayo. I-Methanesulfonic acid ingakhiwa ngokushiswa kwe-methyl mercaptan noma i-dimethyl disulfide ene-oxygen noma i-nitric acid. Ingalungiswa futhi ngesisombululo se-sodium sulfite kanye ne-dimethyl sulfate emanzini ku-100 ° C.
Ukusetshenziswa:
I-Methanesulfonic acid iyikhemikhali ebangela ukuvuvukala, efushaniswe ngokuthi i-MSA, enamathuba amaningi okusetshenziswa emkhakheni we-electroplating futhi ifakazelwe ukuthi iyindawo enhle yokufaka esikhundleni se-fluoroboric acid noma i-phenolic sulfonic acid. Iyinto eluhlaza yemithi kanye nezibulala-zinambuzane, futhi ingasetshenziswa njenge-ejenti yokuqeda amanzi emzimbeni, i-coating curing promoter, i-fibre treatment agent, i-solvent, kanye ne-catalyst yokugeza, i-esterification, kanye ne-polymerization reactions.
Ukupakisha Nokuthumela
250KG/Isigubhu noma ngokwezidingo zamakhasimende.
Ingaletha ngolwandle nangomoya
Isitoreji
I-Methanesulfonic acid iyikhemikhali ebhubhisayo edinga izinyathelo zokuphepha ngesikhathi sokusebenza, njengokugqoka amagilavu okuvikela amakhemikhali, izibuko zokuphepha, kanye nezingubo zokuzivikela.
Uma usebenzisa noma ugcina, gcina kude nemithombo yomlilo kanye namazinga okushisa aphezulu, futhi ugweme ukuthintana nama-oxidants.
Uma usebenzisa, qinisekisa ukuthi indawo yokucwaninga inomoya omuhle futhi ugweme ukuphefumula umusi wayo.
