Ko te Dimethylformamide (whakarāpopototanga DMF), e mōhiotia ana ko N,N-dimethylformamide, he whakakapinga dimethyl o te formamide, ā, kei runga i ngā ngota N (hauota) ngā rōpū methyl e rua, koia te ingoa. Hei rauemi mata matū nui me te whakarewa pai rawa atu, ka whakamahia whānuitia te DMF i roto i te polyurethane, te acrylic, ngā tāpiringa kai, te rongoā, ngā patupatu pepeke, ngā tae, ngā hikohiko me ētahi atu ahumahi.

He wai mārama, kore tae te DMF, he nui te kohua, he iti te hukapapa, he pai te pumau matū me te wera, ā, ka taea te whakaranu ki te wai me te nuinga o ngā whakarewa waro. He whakarewa e whakamahia whānuitia ana mō ngā tauhohenga matū, ā, e kiia ana ko te "whakarewa whānui": Ka whakamahia te DMF. Ko te muka kiriaku i hangaia e te tukanga miro maroke o te muka kiriaku whakarewa he āhuatanga o te pai o te wai, te kaha hipoki kaha, te kakano ngawari, me te kaha o te pa ki te ringa; i roto i te hanga hiako hangai polyester maku, ka taea te whakamahi i te DMF hei horoi me te rongoā mō te kapia polyurethane. Ka whakamahia mō te paninga i ngā rauemi toronga, ā, ina whakamahia mō te tae hiako, ka taea e ia te hanga i te tae o te hiako kia ōrite, kia kore e memeha; nā te kaha o te rewa, ka whakamahia te DMF hei whakarewa i roto i ngā tae, ā, ka whakamahia mō te tae i ngā muka hangai, ka taea te whakapai ake i te ōritetanga o te hiako. Ngā āhuatanga tae; hei whakarewa whiriwhiri e whakamahia ana i roto i ngā tukanga wehenga, ka taea te whakamahi i te DMF mō te mimiti whiriwhiri o ngā momo warowaihā me ngā hau kore-waro. Hei tauira, ka whakamahia te DMF hei horoi i te ethylene hei tango i te acetylene, kia purea ai te ethylene. Ka taea hoki te whakamahi i te DMF hei tango i te isoprene, te piperylene, me ētahi atu mai i te hau putanga o te tipu ethylene hei hanga i te kapia kore-mākū; ka taea hoki te whakamahi i te DMF hei whakarewa whiriwhiri mō ngā tukanga tango i roto i te mara o te tukatuka hinu. Hei tauira: i roto i ngā pūnaha waikawa polycarboxylic he rite ngā āhuatanga, ā, he uaua ki te wehe, pērā i te waikawa isophthalic me te waikawa terephthalic, ka taea te wehe ngāwari mā te tango whakarewa DMF, te whakahou-whakaata rānei i ia taahiraa.

I roto i ngā tauhohenga rauropi, ehara i te mea he whakarewa tauhohenga anake te dimethylformamide, engari he takawaenga nui hoki i roto i te hanganga rauropi. I roto i te umanga rongoā, hei takawaenga rongoā hangai, e whakamahia whānuitia ana i roto i te hanga o te doxycycline, cortisone, me ngā rongoā sulfonamide; i roto i te umanga patu pepeke, e whakamahia ana hei hanga patu pepeke me ngā patu pepeke whai hua me te iti te paitini.

Hei reo tauhohenga mō te hanga matū, ka taea te whakamahi i te DMF hei whakarewa tioata mō te purenga o ngā rongoā. I roto i te umanga hikohiko, ka taea te whakamahi hei whakatika i te matotoru o te kaihoko whakaora mō ngā papa parahi. Ka taea hoki te whakamahi i te DMF hei whakarewa kawe hei hanga i te tioata polymeric me te BF3 (boron trifluoride), ka huri te BF3 mai i te hau ki te totoka, ā, ka ngāwari ki te kawe. Hei whakarewa aprotic polar (hydrophilic) me te ira kohua teitei, ka taea e ia te whakatairanga i te tikanga tauhohenga whakakapinga nucleophilic bimolecular (SN₂). Hei tāpiri, he pānga catalytic tō te dimethylformamide i roto i ngā tauhohenga hydrogenation, dehydrogenation, dehydration me te dehydrohalogenation, e whakaiti ana i te pāmahana tauhohenga me te whakapai ake i te parakore o te hua.

Te āhua nei he tika te taitara o te DMF hei "whakarewa whānui". E kore e roa ka uaua ki te hipa i tēnei momo whakamahinga.
