Okwu mmalite
2,2-Bis (hydroxymethyl) 1,3-propanediol, nke a makwaara dị ka TMP ma ọ bụ trimethylalkyl triol, bụ ngwakọta organic. Ndị a bụ mmalite nke akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: 2,2-Bis (hydroxymethyl) 1,3-propanediol bụ mmiri na-enweghị isi na-acha odo odo.
- Solubility: Ọ na-agbaze na mmiri yana ọtụtụ ihe mgbaze organic dị ka ethers, alcohols, na ketones.
- Nkwụsi ike: Ọ na-akwụsi ike n'okpuru ọnọdụ oxidation, ma ọ ga-emebi n'okpuru ọnọdụ okpomọkụ na ọnọdụ acidic.
Jiri:
- Isi ihe: 2,2-bis (hydroxymethyl) 1,3-propanediol bụ ihe dị n'etiti kemịkalụ na ihe eji eme ihe, nke enwere ike iji mee ka ihe ndị ọzọ na-emepụta ihe.
- Nkwụsị ọkụ: Enwere ike iji ya dị ka ọkụ ọkụ na njikọ nke polyurea polymer material na polymer coatings.
- Nkwadebe nke ogige ester: 2,2-Bis (hydroxymethyl) 1,3-propanediol nwere ike iji kwadebe ogige ester, dị ka polyol polyesters na polyester polymers.
Usoro:
Enwere ike ịkwadebe ya site na mmeghachi omume condensation nke formaldehyde na methanol: nke mbụ, formaldehyde na methanol na-emeghachi omume na methanol n'okpuru ọnọdụ alkaline iji mepụta methanol hydroxyformaldehyde, na mgbe ahụ 2,2-bis (hydroxymethyl) 1,3-propanediol na-emepụta site na mmeghachi omume condensation nke bimolecules na methanol n'okpuru ọnọdụ acidic.
Ozi nchekwa:
- 2,2-Bis (hydroxymethyl) 1,3-propanediol bụ n'ozuzu mma n'okpuru nkịtị ọnọdụ ojiji, ma ndị na-esonụ kwesịrị ịrịba ama:
- Enwere ike imetọ: 2,2-bis (hydroxymethyl) 1,3-propanediol dị na azụmaahịa nwere ike ịnwe obere ihe adịghị ọcha ma ọ bụ ihe na-adịghị ọcha, yabụ kpachara anya ịlele akara ma zụta ngwaahịa sitere n'aka ndị na-eweta ntụkwasị obi mgbe ị na-eji ha.
- mgbakasị ahụ akpụkpọ: Ọ nwere ike ịkpasu iwe na akpụkpọ ahụ na anya, na ekwesịrị ịme ihe nchekwa dị mkpa mgbe a na-emetụ ya aka, dị ka iyi uwe kemịkal na enyo enyo, na izere kọntaktị kpọmkwem.
- Ọnọdụ nchekwa: Ekwesịrị ịchekwa ogige ahụ n'ebe gbara ọchịchịrị, akọrọ na nke ọma, pụọ na ọkụ, okpomọkụ dị elu, na oxidants.
- Nsi: 2,2-Bis (hydroxymethyl) 1,3-propanediol bụ obere ihe na-egbu egbu, ma a ka kwesịrị izere maka ntinye ma ọ bụ iku ume.
