Kaihanga Utu Pai Dimethyl Sulfoxide (DMSO) CAS 67-68-5

whakaahuatanga poto:

Ko te Dimethyl sulfoxide (e kiia nei ko te DMSO) he matū waro kei roto he whanariki, ko te Dimethylsulfoxide Ingarihi, ko te tātai ngota ko (CH3) 2SO, he wai kore tae, kore kakara, mārama hoki i te pāmahana rūma, he wai mura hygroscopic, ā, he teitei te polarity. , he teitei te kohua, he aprotic, ka taea te whakaranu ki te wai, he tino iti te paitini, he pai te pumau o te wera, kāore e taea te whakaranu ki ngā alkane, ka wairewa i roto i te nuinga o ngā matū waro pēnei i te wai, te etanoru, te propanol, te ether, te benzene me te chloroform, e mōhiotia ana ko te "whakarewa ao".

whakaahuatanga

Ko tētahi o ngā whakarewa rauropi e whakamahia whānuitia ana, ā, ko te wairewatanga tino kaha. Ka taea e ia te whakarewa i te nuinga o ngā mea rauropi, tae atu ki ngā warowaihā, ngā pūmua, ngā peptide, me te maha o ngā tote me ngā hau kore-rauropi. Ka taea e ia te whakarewa i te 50-60% o tōna ake taumaha o te wairewa (ko ētahi atu whakarewa whānui ka taea te whakarewa i te 10-20%) anake, nō reira he mea tino nui i roto i te whakahaere tauira me te tirotiro rongoā tere-tere. I raro i ētahi āhuatanga, ka puta he tauhohenga pahū ina pā te Dimethyl sulfoxide ki te waikawa chloride. He whānuitia te whakamahinga o te Dimethyl sulfoxide hei whakarewa me te matū, inā koa hei whakarewa tukatuka me te whakarewa hurihuri i roto i te polymerization acrylonitrile, hei whakarewa hanga polyurethane me te whakarewa hurihuri, hei whakarewa hanga polyamide, polyimide me te polysulfone resin, ngā matū me ngā hauwaiwaro kakara, ngā whakarewa tango butadiene me ngā whakarewa mō te hanga chlorofluoroaniline, me ētahi atu. Hei tāpiri, i roto i te umanga rongoā, ka whakamahia tika hoki te dimethyl sulfoxide hei rauemi mata me te kawe i ētahi rongoā. He pānga ārai-mumura, whakamamae mamae, diuretic, whakangāwari me ētahi atu pānga anō hoki tō te dimethyl sulfoxide, e mōhiotia ana ko te "panacea", ā, he maha ngā wā ka tāpirihia ki ngā rongoā hei wāhanga hohe o ngā rongoā whakamamae mamae. He āhuatanga motuhake tōna, arā, ko te uru ngāwari ki te kiri, ka puta he reka rite ki te tio ki te kaiwhakamahi. Ka taea e te konutai cyanide i roto i te dimethyl sulfoxide te whakararu i te cyanide mā te pa ki te kiri. Ā, he iti ake te paitini o te dimethyl sulfoxide. Ka whakamahia te dimethyl sulfoxide hei tangohanga e te nuinga o ngā kamupene matū me ngā kamupene rongoā. Heoi, nā te teitei o te pāmahana kohua o te DMSO, he tino teitei te pāmahana whakahaere, ka hua ake te wera o ngā rauemi, ka pā ki te whakaora o te dimethyl sulfoxide me te horoi taputapu. Whakanuia te whakapaunga pūngao. Nō reira, kua noho te whakaora o te DMSO hei arai mō tōna whakamahinga whānui hei tangohanga. Ko te dimethyl sulfoxide he whakarewa rauropi aprotic noa e whakamahia ana hei whakarewa i ngā matū polar me ngā matū nonpolar. Ko te āhua kua wehea, te DMSO-d6 (D479382), e whakamahia ana mō ngā rangahau NMR, he ngāwari te tautuhi mā tōna whānuitanga NMR nā tōna kaha ki te whakarewa i te nuinga o ngā tātaritanga.

Ngā tono o te DMSO

1. E whakamahia ana te DMSO mō te tango hauwai kakara, te reo tauhohenga mō te kapia me te tae, te whakapūhui muka kiriaku, me te whakarewa mō te miro, me ētahi atu.

2. Ka taea te whakamahi i te DMSO hei whakarewa waro, hei reo tauhohenga me te takawaenga hanga waro. He tino maha ngā whakamahinga. He tino kaha te tango whiriwhiri o tēnei hua, e whakamahia ana hei whakarewa polymerization me te condensation o te kapia kiriaku me te kapia polysulfone, hei whakarewa polymerization me te miro o te muka polyacrylonitrile me te acetate, hei whakarewa tango o te wehenga alkane me te warowaihā kakara. He warowaihā kakara, he tango butadiene, he miro muka kiriaku, he whakarewa kirihou me te reo tauhohenga mō ngā tae hanga waro, ngā rongoā me ētahi atu ahumahi. Mō te rongoā, he pānga ārai-mumura me te whakamamae te dimethyl sulfoxide, ā, he kaha te uru ki te kiri, nō reira ka taea e ia te whakarewa i ētahi rongoā i roto i te Chemicalbook, kia taea ai e aua rongoā te uru ki roto i te tinana tangata kia tutuki ai te kaupapa o te maimoatanga. Mā te whakamahi i tēnei āhuatanga kawe o te dimethyl sulfoxide, ka taea hoki te whakamahi hei tāpiri mō ngā patupatu.
