Okwu mmalite
Acetone aldehyde dimethanol, nke a makwaara dị ka acetone methanol. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke acetone aldehyde dimethanol:
Ogo:
Acetone aldehyde dimethanol bụ mmiri mmiri na-acha odo odo na-esi ísì ụtọ. Ọ bụ ngwakọta organic nke na-agbaze na mmiri, alcohols, na ethers. Acetone aldoldehyde methanol adịghị eguzosi ike, na-adị mfe hydrolyzed na oxidized, ọ dị mkpa ka echekwara ya na oyi na ọchịchịrị ebe, na-na na-adịghị oxygen, okpomọkụ na mgbanye isi mmalite.
Jiri:
A na-ejikarị acetone aldoldehyde dimethanol eme ihe dị ka onye etiti na njikọ organic. Enwere ike iji ya na nkwadebe nke esters, ethers, amides, polymers, na ụfọdụ ogige organic. A na-ejikwa Pyrudaldehyde methanol mee ihe dị ka ihe mgbaze, mmiri mmiri na ihe mgbakwunye na mkpuchi na ụlọ ọrụ plastik.
Usoro:
Enwere ụzọ dị iche iche iji kwadebe acetone aldehyde dimethanol. A na-enweta usoro a na-ahụkarị site na mmeghachi omume condensation nke methanol na acetone. Na nkwadebe, methanol na acetone na-agwakọta n'otu akụkụ nke molar ma meghachi omume n'ihu ihe na-akpata acidic, nke na-achọkarị ikpokọta ngwakọta mmeghachi omume. Mgbe emechara mmeghachi omume ahụ, a na-enweta acetone aldoldehyde dimethanol dị ọcha site na distillation, crystallization ma ọ bụ ụzọ nkewa ndị ọzọ.
Ozi nchekwa:
Acetone aldoldemic methanol bụ ihe na-akpasu iwe na ekwesịrị izere ya na kọntaktị na akpụkpọ ahụ, anya, na akpụkpọ anụ mucous. Ekwesịrị ịme ikuku ikuku dị mma n'oge a na-arụ ọrụ, yana uwe mkpuchi na anya mkpuchi kwesịrị iyi. Mgbe a na-edozi na nchekwa, a ga-emechi akpa ahụ nke ọma na okpomọkụ, mgbanye na oxidants. Ọ bụrụ na etinyere ya ma ọ bụ kuruo ume, chọọ nlekọta ahụike ozugbo.
