Isticmaalka
Aashitada Methanesulfonic waa aashitada alkyl sulfonic ugu fudud. Dareere aan midab lahayn. Si fudud ayaa loogu milmi karaa biyaha, xoogaa ku milmi kara dareere dabiici ah. Aashitada xooggan oo leh pKa oo ah -0.6. Lama biyo-shubo biyaha kulul ama xalka alkaline-ka kulul. Aashitada Methanesulfonic waxaa lagu samayn karaa oksaydheynta methyl mercaptan ama dimethyl disulfide oo leh oksijiin ama nitric acid. Waxa kale oo lagu diyaarin karaa xal sodium sulfite iyo dimethyl sulfate oo biyo ah heerkul ah 100 ° C.
Isticmaalka:
Aashitada Methanesulfonic waa walax kiimiko ah oo caustic ah, oo loo soo gaabiyo MSA, taasoo leh fursado ballaaran oo lagu isticmaalo goobta electroplating waxaana la xaqiijiyay inay tahay beddel wanaagsan oo loogu talagalay fluoroboric acid ama phenolic sulfonic acid. Waa walax ceeriin ah oo loogu talagalay daawada iyo sunta cayayaanka, waxaana sidoo kale loo isticmaali karaa sidii wakiil fuuq-baxa, kor u qaadaha daaweynta dahaarka, wakiilka daaweynta faybarka, dareeraha, iyo kicinta dhaqidda, esterification, iyo falcelinta polymerization.
Baakadeynta iyo Rarista
250KG/Durbaan ama sida looga baahan yahay macaamiisha.
Waxaa lagu keeni karaa bad iyo hawada
Kaydinta
Aashitada Methanesulfonic waa kiimiko daxal leh oo u baahan tallaabooyin badbaado inta lagu jiro hawlgalka, sida xirashada galoofyada ilaalinta kiimikada, muraayadaha badbaadada, iyo dharka ilaalinta.
Markaad isticmaaleyso ama kaydineyso, ka fogow ilaha dabka iyo heerkulka sare, iskana ilaali inaad la xiriirto oksaydhiyeyaasha.
Markaad isticmaaleyso, hubi jawi shaybaadh oo hawo fiican leh oo iska ilaali inaad neefsato uumiga.
