Polokelo
Kaha Dimethyl Formamide (DMF) ke k'hemik'hale ea tlhaho e nang le thepa e tukang le e feto-fetohang, 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 kenang hantle, ho qoba khanya ea letsatsi le mocheso o phahameng. Sebaka sa polokelo se lokela ho ba hole le mollo, mocheso le libaka tse thibelang ho phatloha.
2. Sephutheloana: DMFS e lokela ho bolokoa ka har'a lijana tse sa keneng moea tsa boleng bo tsitsitseng, joalo ka libotlolo tsa khalase, libotlolo tsa polasetiki kapa meropa ea tšepe. Botšepehi le ho tiea ha lijana li lokela ho hlahlojoa khafetsa.
3. Thibela pherekano: DMF ha ea lokela ho kopanngoa le oxidant e matla, asiti e matla, motheo o matla le lintho tse ling ho qoba likarabelo tse kotsi. Nakong ea polokelo, ho kenya, ho theola le ho sebelisa, tlhokomelo e lokela ho lefshoa ho thibela ho thulana, khohlano le ho thothomela, ho qoba ho lutla le likotsi.
4. Thibela motlakase o sa fetoheng: Mokhoeng oa polokelo, ho kenya, ho laolla le ho sebelisa DMF, ho lokela ho thibela tlhahiso ea motlakase o sa fetoheng. Mehato e nepahetseng e lokela ho nkuoa, joalo ka ho thella fatše, ho koahela, lisebelisoa tse thibelang ho fetoha ha mocheso, jj.
5. Ho tsebahatsa mabitso: Dijana tsa DMF di lokela ho tshwauwa ka mabitso a hlakileng le boitsebiso, ho bontsha letsatsi la polokelo, lebitso, kgokahanyo, bongata le tlhahisoleseding e nngwe, e le ho nolofatsa tsamaiso le boitsebiso.
