Intangiriro
Tetramethylguanidine, izwi kandi nka N, N-dimethylformamide, ni kirisiti itagira ibara. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya tetramethylguanidine:
Ubwiza:
- Tetramethylguanidine ni alkaline ikomeye kandi irashobora gukora igisubizo gikomeye cya alkaline mumuti wamazi.
- Ni ishingiro ridakomeye rihwanye n'umuti wa anhydrous, kandi urashobora gukoreshwa nkuwakiriye hydrogene ion.
- Irakomeye mubushyuhe bwicyumba, ariko irashobora guhita ihindagurika muri gaze itagira ibara iyo ishyushye.
- Ni uruganda rufite hygroscopicity ikomeye.
Koresha:
- Tetramethylguanidine ikoreshwa cyane nka catalizike ya alkali muri reaction ya synthesis.
- Irashobora kandi gukoreshwa mu nganda nko guhuza irangi, amashanyarazi, amashanyarazi ya polyurethane yoroheje, nibindi.
Uburyo:
- Tetramethylguanidine irashobora gutegurwa nigisubizo cya N, N-dimethylformamide hamwe na gaze ya amoniya kumuvuduko mwinshi.
- Ubu buryo busanzwe busaba ubushyuhe kandi bukorwa mukurinda gaze ya inert.
Amakuru yumutekano:
- Tetramethylguanidine ni uburozi kandi bugomba kwirindwa guhura nuruhu n'amaso. Wambare uturindantoki two kurinda hamwe na gogles mugihe ukoresha.
- Irashobora gutera uburibwe bwamaso nuruhu, kandi bigatera ingorane zo guhumeka nibimenyetso byuburozi.
- Hagomba kwitonderwa kugirango wirinde guhura na okiside, acide nibintu byaka mugihe cyo gukoresha no kubika.
- Mugihe ukoresha tetramethylguanidine, hagomba gukurikizwa uburyo bukwiye bwo gukora laboratoire hamwe na protocole ikora neza.
