Whakamahinga
Ko te waikawa methanesulfonic te waikawa alkyl sulfonic māmā rawa atu. He wai kore tae. He ngāwari ki te rewa ki te wai, he paku rewa ki ngā whakarewa waro. He waikawa kaha me te pKa o te -0.6. Kāore e waikuratia ki te wai wera, ki te otinga kawakore wera rānei. Ka taea te hanga waikawa methanesulfonic mā te waikura o te methyl mercaptan, te dimethyl disulfide rānei me te hāora, te waikawa hauota rānei. Ka taea hoki te whakarite mā te otinga o te konutai sulfite me te dimethyl sulfate ki te wai i te 100°C.
Whakamahinga:
Ko te waikawa methanesulfonic he matū kawa, e whakarapopototia ana ko MSA, he whānui ngā tono i roto i te mara o te whakakikorua hiko, ā, kua whakamātauhia he whakakapi pai mō te waikawa fluororoboric, te waikawa phenolic sulfonic rānei. He rauemi mata mō te rongoā me ngā patu pepeke, ā, ka taea hoki te whakamahi hei kaihoko whakamaroke, hei kaiwhakatairanga whakamaroke paninga, hei kaihoko maimoatanga muka, hei whakarewa, hei whakakorikori mō te horoi, te whakaester, me ngā tauhohenga polymerization.
Te Tākai me te Tukunga
250KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Ka taea te tuku mā te moana me te rangi
Rokiroki
He matū waikura te waikawa methanesulfonic e hiahia ana kia whakamahia ngā tikanga haumaru i te wā e whakamahia ana, pērā i te mau karapu tiaki matū, ngā mōhiti tiaki, me ngā kākahu tiaki.
I te wā e whakamahia ana, e rongoa ana rānei, me waiho kia matara atu i ngā pūtake ahi me ngā pāmahana tiketike, ā, kaua e pā ki ngā waikura.
I te wā e whakamahia ana, kia pai te hauhautanga o te taiao taiwhanga, ā, kia kaua e hongihia ōna kohu.
