Polokelo
Joaloka Dibethyl formamide (DMF) ke lik'hemik'hale tsa manyolo ka mefuta e metle le e sa tloaelehang, lintlha tse latelang li lokela ho hlokomeloa nakong ea polokelo:
1. Tikoloho ea polokelo: DMF e lokela ho bolokoa tikolohong e pholileng, e omileng le e nang le moea o futhumetseng, qoba khanya ea letsatsi le mocheso o phahameng. Sebaka sa polokelo se lokela ho ba hole le mollo, mocheso le oxidant, litloaelo tse phatlohang.
2. Ho boloka: DMFS e lokela ho bolokoa ka lijana tsa moea oa moea oa moea o tsitsitseng, joalo ka botlolo ea khalase, libotlolo tsa polasetiki kapa meropa ea tšepe. Ho tšepahala le ho tiea ha lijana ho lokela ho hlahlojoa khafetsa.
3. Thibela pherekano: DMF ha ea lokela ho tsoakoa ka matla a matla a oxidant, acid e matla le lintho tse ling tse lokelang ho qoba karabelo e kotsi. Ts'ebetsong ea polokelo, ho jarolla, ho laolla le ho e sebelisa, ho lokela ho lefuoa ho thibela ho thulana, likhohlano le ho sisinyeha, ho qoba ho tlola le likotsi.
4. Thibela motlakase oa ho emisa: ho polokelo ea DMF, ho kenya, ho laolla le ho sebelisa tšebetso, e lokela ho thibela moloko oa motlakase oa lipalo. Mehato e loketseng e lokela ho nkuoa, joalo ka ho ipehela, ho koaheloa, lisebelisoa tsa khalemente, joalo-joalo,
5. Barapeli ba ngola: Litsebi tsa DMF li lokela ho tšoauoa ka mabitso a hlakileng le tsebiso, ho bontša letsatsi la polokelo, lebitso, le tsepamiso, e le hore u tsebe ho tsamaisa taolo le tlhaiso-leseling.
