Intshayelelo
I-Tetramethylguanidine, ekwabizwa ngokuba yi-N,N-dimethylformamide, yinto eqinileyo yecrystalline engenambala. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-tetramethylguanidine:
Umgangatho:
- I-Tetramethylguanidine i-alkaline enamandla kwaye inokwenza isisombululo esinamandla se-alkaline kwisisombululo esinamanzi.
- Isiseko esibuthathaka esilingana nesisombululo se-anhydrous, kwaye sinokusetyenziswa njengomamkeli we-hydrogen ion.
- Iqinile kwiqondo lobushushu begumbi, kodwa inokujika ngokukhawuleza ibe yirhasi engenambala xa ishushu.
- Yikhompawundi ene-hygroscopicity eyomeleleyo.
Sebenzisa:
-I-Tetramethylguanidine isetyenziswa ikakhulu njenge-alkali catalyst kwi-organic synthesis reactions.
- Inokusetyenziswa kwakhona kumashishini afana ne-dayi intermediates, i-electroplating, i-flexible polyurethane foams, njl.
Indlela:
- I-Tetramethylguanidine inokulungiswa ngokuphendula kwe-N, N-dimethylformamide kunye negesi ye-ammonia kuxinzelelo oluphezulu.
- Le nkqubo idla ngokufuna ukufudumeza kwaye iqhutywe phantsi kokukhuselwa kwegesi ye-inert.
Ulwazi ngoKhuseleko:
- I-Tetramethylguanidine yityhefu kwaye kufuneka ithintelwe ngokudibana nolusu kunye namehlo. Nxiba iiglavu zokukhusela kunye nezibuko xa usebenzisa.
- Inokubangela ukucaphuka kwamehlo kunye nolusu, kwaye ibangele ubunzima bokuphefumla kunye neempawu zetyhefu.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa ne-oxidants, i-acids kunye nezinto ezinokutsha ngexesha lokusetyenziswa kunye nokugcinwa.
- Xa uphethe i-tetramethylguanidine, iinkqubo ezifanelekileyo zokusebenza zelabhoratri kunye nemigaqo yokuphatha ngokukhuselekileyo kufuneka ilandelwe.
