Okwu mmalite
Tetramethylguanidine, nke a makwaara dị ka N, N-dimethylformamide, bụ kristal siri ike na-enweghị agba. Ihe na-esonụ bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke tetramethylguanidine:
Ogo:
- Tetramethylguanidine bụ alkaline siri ike ma nwee ike ịmepụta ngwọta alkaline siri ike na ngwọta mmiri.
- Ọ bụ ntọala na-adịghị ike ya na ngwọta anhydrous, enwere ike iji ya dị ka onye na-enweta ion hydrogen.
- Ọ siri ike na ụlọ okpomọkụ, mana ọ nwere ike ịbanye ngwa ngwa n'ime gas na-enweghị agba mgbe ọ na-ekpo ọkụ.
- Ọ bụ ngwakọta nwere hygroscopicity siri ike.
Jiri:
- A na-ejikarị Tetramethylguanidine mee ihe dị ka ihe na-akpata alkali na mmeghachi omume njikọ organic.
- A pụkwara iji ya mee ihe na ụlọ ọrụ ndị dị ka intermediates agba agba, electroplating, polyurethane foams na-agbanwe agbanwe, wdg.
Usoro:
- Enwere ike ịkwadebe Tetramethylguanidine site na mmeghachi omume nke N, N-dimethylformamide na gas amonia na nrụgide dị elu.
- Usoro a na-achọkarị ikpo ọkụ ma na-eme ya n'okpuru nchebe nke gas inert.
Ozi nchekwa:
- Tetramethylguanidine bụ ihe na-egbu egbu ma ekwesịrị izere ya na kọntaktị na akpụkpọ ahụ na anya. Yiri gloves nchebe na anya mgbe ị na-eji.
- O nwere ike ịkpasu anya na mgbakasị anụ ahụ, na-ebutekwa nsogbu iku ume na mgbaàmà nsi.
- Ekwesịrị ịkpachara anya ka ị ghara ịkpọtụrụ oxidants, acids na ihe ndị na-ere ọkụ n'oge eji na nchekwa.
- Mgbe ị na-eji tetramethylguanidine eme ihe, ekwesịrị ịgbaso usoro ọrụ ụlọ nyocha kwesịrị ekwesị yana ụkpụrụ njikwa nchekwa.
