HANGANGA:
Tirohanga Whānui:
Ko te Dimethyl sulfoxide (DMSO) he matū waro kei roto he whanariki; ko te tauira ngota: (CH3) 2SO; Ka whakaatuhia he wai mārama, kore kakara, he wai hygroscopic, he wai mura i te pāmahana rūma. He teitei te polarity me te pāmahana koropupū teitei. He āhuatanga aprotic me te wai-ranu hoki. He iti te paitini, he pai te pumau wera, ā, kāore e uru ki te paraffin. Ka wairewa ki te wai, te etanoru, te propanol, te ether, te benzene me te chloroform me te maha atu o ngā momo matū waro, ā, ka kiia ko te "whakarewa whānui." He whakarewa waro noa e kaha ana ki te wairewa. Ka taea e ia te wairewa i te nuinga o ngā matū waro tae atu ki ngā warowaihā, ngā polymer, ngā peptide, me te maha o ngā tote me ngā hau inorganic. Ka taea e ia te wairewa i tētahi nui o te matū wairewa e rite ana ki te 50-60% o ia anō (ko ētahi atu whakarewa noa ka wairewa noa i te 10-20%), nō reira he mea tino nui ki te whakahaere tauira me te tirotiro tere o ngā rongoā. I raro i ētahi āhuatanga, ka taea e te pānga i waenga i te dimethyl sulfoxide me te chloride te arahi ki tētahi tauhohenga pahū.

Whakamahinga
1. Ka taea te whakamahi mō te tango i te arene, hei reo tauhohenga hoki mō ngā kapia me ngā tae, ā, ka whakamahia ki te polymerization kiriaku me te whakarewa miro.
2. Ka taea te whakamahi hei whakarewa waro, hei reo tauhohenga, hei takawaenga hoki mō te hanga waro. He tino maha ngā whakamahinga. He tino whiriwhiri te kaha o tēnei hua ki te tango, ā, ka taea te whakamahi hei whakarewa whakapūhui me te whakapūmau o te kapia kiriaku me te kapia polysulfone, hei whakarewa whakapūhui me te hurihuri o te polyacrylonitrile me te cellulose acetate, hei whakarewa tango mō te wehewehe i ngā alkane me ngā arene, hei reo tauhohenga hoki mō ngā arene, te tango butadiene, te muka kiriaku, ngā whakarewa kirihou, ngā tae waro me ngā tae hangai, me ngā ahumahi rongoā. I roto i te mara rongoā, he pānga ārai-mumura me te whakamamae te dimethyl sulfoxide me te kaha kaha ki te uru mā roto i te kiri, ā, ka taea te whakarewa i ētahi rongoā me te whakanui ake i tō rātou uru ki roto i te tinana tangata kia tutuki ai ngā kaupapa rongoā. Mā te tango i tēnei āhuatanga kawe o te dimethyl sulfoxide ka taea te whakamahi hei tāpiri patu pepeke. Mā te tāpiri i te iti o te dimethyl sulfoxide ki roto i ētahi patu pepeke ka taea te whakahaere i te uru o ngā patu pepeke ki roto i te tipu hei whakapai ake i te whai huatanga. Ka taea hoki te whakamahi i te dimethyl sulfoxide hei whakarewa tae, hei tango tae, hei kawe tae mō ngā muka hangai. Ka taea hoki te whakamahi hei mimiti i te hangarua o te acetylene me te whanariki hauhā, me ngā whakarerekētanga o te muka hangai, te ātete huka me te pūnga hiko, te hinu parai, me te tango i ngā konganuku onge.
3. Ka taea te whakamahi hei whakarewa tātari me te kaihoko whakatika o te chromatography hau me te whakarewa mō te tātari i ngā hihi UV.
