Kushandiswa
Methanesulfonic acid ndiyo alkyl sulfonic acid iri nyore. Mvura isina ruvara. Iri nyore kunyungudika mumvura, inonyungudika zvishoma mu organic solvents. Acid yakasimba ine pKa ye -0.6. Haina hydrolyzed mumvura inopisa kana hot alkaline solution. Methanesulfonic acid inogona kugadzirwa nekuoxidation yemethyl mercaptan kana dimethyl disulfide ne oxygen kana nitric acid. Inogonawo kugadzirwa ne sodium sulfite uye dimethyl sulfate mumvura pa 100 ° C.
Mashandisirwo:
Methanesulfonic acid chinhu chinokonzerwa nemakemikari, chakapfupikiswa seMSA, chine mikana yakawanda yekushandiswa mu electroplating uye chakaratidzwa kuti chinotsiva fluoroboric acid kana phenolic sulfonic acid. Chinhu chisina kugadzirwa chemishonga nemishonga yezvipembenene, uye chinogona kushandiswawo semushonga unobvisa mvura mumuviri, mushonga wekudzivirira kusvibiswa, mushonga wekurapa fiber, musanganiswa wezvinhu zvinonyungudutsa, uye musanganiswa wekugadzirisa kusvibiswa, esterification, uye polymerization reactions.
Kurongedza uye Kutumira
250KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Inogona kuendesa negungwa nemhepo
Kuchengetera
Methanesulfonic acid ikemikari inoparadza inoda matanho ekuchengetedza panguva yekushanda, akadai sekupfeka magirovhosi ekudzivirira emakemikari, magirazi ekuchengetedza, uye mbatya dzekudzivirira.
Pakushandisa kana kuchengeta, chengetedza kure nezvinhu zvinokonzera moto uye tembiricha yakakwira, uye dzivisa kusangana nezvinokonzera oxidants.
Paunenge uchishandisa, iva nechokwadi chekuti nzvimbo yekurabhoritari ine mhepo yakakwana uye usafeme mweya wayo.
