Mawu Oyamba
Tetramethylguanidine, yomwe imadziwikanso kuti N,N-dimethylformamide, ndi kristalo wopanda mtundu wolimba. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha tetramethylguanidine:
Ubwino:
- Tetramethylguanidine ndi wamchere kwambiri ndipo imatha kupanga njira yamphamvu yamchere mumchere wamadzi.
- Ndi maziko ofooka ofanana ndi yankho la anhydrous, ndipo atha kugwiritsidwa ntchito ngati wolandila ma ayoni a haidrojeni.
- Ndiwolimba kutentha firiji, koma amatha kusinthasintha mwachangu kukhala mpweya wopanda mtundu ukatenthedwa.
- Ndi gulu lolimba la hygroscopicity.
Gwiritsani ntchito:
- Tetramethylguanidine amagwiritsidwa ntchito makamaka ngati chothandizira zamchere muzochita za organic synthesis.
- Itha kugwiritsidwanso ntchito m'mafakitale monga dye intermediates, electroplating, flexible polyurethane thovu, etc.
Njira:
- Tetramethylguanidine ikhoza kukonzedwa ndi zomwe N,N-dimethylformamide ndi mpweya wa ammonia pamphamvu kwambiri.
- Njirayi nthawi zambiri imafuna kutentha ndipo imachitika motetezedwa ndi mpweya wa inert.
Zambiri Zachitetezo:
- Tetramethylguanidine ndi mankhwala oopsa ndipo sayenera kukhudzana ndi khungu ndi maso. Valani magolovesi oteteza ndi magalasi mukamagwiritsa ntchito.
- Zimayambitsa kuyabwa m'maso ndi pakhungu, ndikupangitsa kupuma movutikira komanso zizindikiro za poizoni.
- Chisamaliro chiyenera kutengedwa kuti musakhudzidwe ndi okosijeni, zidulo ndi zinthu zoyaka moto mukamagwiritsa ntchito ndikusunga.
- Pogwira ntchito ya tetramethylguanidine, njira zoyenera zogwirira ntchito mu labotale ndi njira zoyendetsera bwino ziyenera kutsatiridwa.
