Hoʻohana
ʻO ka waikawa Methanesulfonic ka waikawa alkyl sulfonic maʻalahi loa. Wai ʻole kala. Maʻalahi e hoʻoheheʻe i ka wai, hoʻoheheʻe iki ʻia i nā mea hoʻoheheʻe organik. ʻAkika ikaika me ka pKa o -0.6. ʻAʻole i hydrolyzed i ka wai wela a i ʻole ka hopena alkaline wela. Hiki ke hoʻokumu ʻia ka waikawa Methanesulfonic ma ka oxidation o ka methyl mercaptan a i ʻole dimethyl disulfide me ka oxygen a i ʻole ka waikawa nitric. Hiki ke hoʻomākaukau ʻia e kahi hopena o ka sodium sulfite a me ka dimethyl sulfate i loko o ka wai ma 100 ° C.
Hoʻohana:
ʻO ka waikawa Methanesulfonic kahi mea kemika caustic, i hoʻopōkole ʻia ʻo MSA, nona nā manaʻolana hoʻohana ākea ma ke kahua o ka electroplating a ua hōʻoia ʻia he pani maikaʻi no ka waikawa fluororoboric a i ʻole ka waikawa phenolic sulfonic. He mea maka ia no nā lāʻau lapaʻau a me nā pesticides, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaloʻo, mea hoʻolaha hoʻōla uhi, mea mālama fiber, mea hoʻoheheʻe, a me ka mea hoʻoulu no ka holoi ʻana, esterification, a me nā hopena polymerization.
ʻŌpala a me ka Hoʻouna ʻana
250KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Hiki ke hāʻawi ʻia ma ke kai a me ka lewa
Ka Waihona
He kemika ʻino ka methanesulfonic acid e pono ai nā hana palekana i ka wā o ka hana, e like me ke komo ʻana i nā mīkina lima pale kemika, nā goggles palekana, a me nā lole pale.
I ka wā e hoʻohana ai a mālama paha, e mālama ʻia mai nā kumu ahi a me nā mahana kiʻekiʻe, a pale i ka hoʻopili ʻana me nā mea oxidants.
I ka wā e hoʻohana ai, e hōʻoia i kahi wahi hoʻokolohua ea maikaʻi a pale i ka hanu ʻana i kona mahu.
