Selelekela
2,2-Bis(hydroxymethyl)1,3-propanediol, e tsejoang hape e le TMP kapa trimethylalkyl triol, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:
Boleng:
- Ponahalo: 2,2-Bis(hydroxymethyl)1,3-propanediol ke mokelikeli oa viscous o se nang 'mala ho ea mosehla.
- Solubility: E qhibiliha ka metsing le mefuta e fapaneng ea lihlapolli tsa tlhaho tse kang ethers, alcohols, le ketones.
- Botsitso: E batla e tsitsitse tlas'a maemo a tloaelehileng a oxidation, empa e tla bola tlas'a mocheso o phahameng le maemo a acidic.
Sebelisa:
- Ntho ea motheo: 2,2-bis(hydroxymethyl)1,3-propanediol ke lik'hemik'hale tse mahareng le tsa motheo tse tala, tse ka sebelisoang ho kopanya metsoako e meng ea tlhaho.
- Retardant ea malakabe: E ka sebelisoa e le ntho e thibelang lelakabe ha ho qaptjoa thepa ea polyurea polymer le liphahlo tsa polymer.
- Ho lokisetsa metsoako ea ester: 2,2-Bis (hydroxymethyl) 1,3-propanediol e ka sebelisoa ho lokisa metsoako ea ester, e kang polyol polyester le polyester polymers.
Mokhoa:
- E ka lokisoa ke karabelo ea condensation ea formaldehyde le methanol: pele, formaldehyde le methanol li sebetsanoa le methanol tlas'a maemo a alkaline ho theha methanol hydroxyformaldehyde, ebe 2,2-bis(hydroxymethyl)1,3-propanediol e thehoa ke karabelo ea condensation ea li-bimolecules le methanol tlas'a maemo a asiti.
Lintlha tsa Tšireletseho:
- 2,2-Bis(hydroxymethyl)1,3-propanediol hangata e bolokehile tlas'a maemo a tloaelehileng a tšebeliso, empa tse latelang li lokela ho hlokomeloa:
- E ka 'na ea e-ba le litšila: 2,2-bis(hydroxymethyl)1,3-propanediol e fumanehang khoebong e ka' na ea e-ba le litšila tse nyenyane kapa litšila, kahoo e-ba hlokolosi ho hlahloba leibole le ho reka lihlahisoa ho tsoa ho barekisi ba tšepahalang ha u li sebelisa.
- Ho halefa ha letlalo: E ka 'na ea e-ba le phello e senyang letlalong le mahlo,' me mehato e hlokahalang ea tšireletso e lokela ho nkoa ha e ama, e kang ho roala li-gloves tsa lik'hemik'hale le likhalase, le ho qoba ho kopana ka ho toba.
- Maemo a polokelo: Motsoako o lokela ho bolokoa sebakeng se lefifi, se omeletseng le se nang le moea o motle, hole le mollo, mocheso o phahameng le li-oxidants.
- Chefo: 2,2-Bis(hydroxymethyl)1,3-propanediol ha e na chefo e fokolang, empa e ntse e lokela ho qojoa bakeng sa ho kenngoa kapa ho hema.
