Hoʻolauna
ʻO Tetramethylguanidine, i ʻike ʻia ʻo N, N-dimethylformamide, he paʻa kalakala kala ʻole. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka tetramethylguanidine:
ʻAno maikaʻi:
- He alkaline ikaika ka Tetramethylguanidine a hiki ke hana i ka hopena alkaline ikaika i ka wai.
- He kumu nāwaliwali ia e like me ka hopena anhydrous, a hiki ke hoʻohana ʻia e like me ka loaʻa ʻana o nā ion hydrogen.
- Paʻa ia ma ka lumi wela, akā hiki ke hoʻololi koke i loko o ke kinoea kala ʻole ke hoʻomehana ʻia.
- He hui ia me ka hygroscopicity ikaika.
E hoʻohana:
- Hoʻohana nui ʻia ʻo Tetramethylguanidine ma ke ʻano he catalyst alkali i nā hopena synthesis organik.
- Hiki ke hoʻohana ʻia i nā ʻoihana e like me ka dye intermediates, electroplating, flexible polyurethane foams, etc.
Hanana:
- Hiki ke hoʻomākaukau ʻia ʻo Tetramethylguanidine e ka hopena o N,N-dimethylformamide me ke kinoea amonia ma ke kaomi kiʻekiʻe.
- Pono kēia kaʻina hana i ka hoʻomehana a hana ʻia ma lalo o ka pale o kahi kinoea inert.
ʻIke palekana:
- ʻO Tetramethylguanidine kahi mea ʻawaʻawa a pono e pale ʻia i ka pili ʻana me ka ʻili a me nā maka. E hoʻohana i nā mīkina lima pale a me nā maka aniani ke hoʻohana.
- Hiki iā ia ke hōʻeha i ka maka a me ka ʻili, a me ka pilikia o ka hanu a me nā hōʻailona make.
- Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā waikawa a me nā mea hiki ke ahi i ka wā o ka hoʻohana ʻana a me ka mālama ʻana.
- I ka lawelawe ʻana i ka tetramethylguanidine, pono e hahai ʻia nā kaʻina hana hoʻokolohua kūpono a me nā protocol mālama palekana.
