Meatotino oloa:
1. Pa'epa'e po'o sina samasama manino vai ma le manogi manogi. Solu i le vai; ethanol; eteru ma chloroform, ma isi, le mautu, pala pe a fegalegaleai ma alkali po'o fa'amama i le mamafa o le ea. E le mautu, pala pe a fegalegaleai ma alkali pe fa'amama i le mamafa o le ea.
2.O le oloa e maualalo le oona, foloina le oloa e matua faʻasaina, e tatau i le tagata faʻapipiʻi ona ofuina ni mea e puipui ai.
3.Chemical meatotino: Diacetone alcohol o loʻo i ai carbonyl ma hydroxyl i le mole, faʻatasi ai ma le vailaʻau o le ketone ma le ava malosi. O le pala e tupu pe a vevela i le 130°C poʻo luga atu ma le alkali, e maua ai 2 mole o le acetone. Pe a faʻavevela ile sulfuric acid poʻo le tele ole iodine, e faʻamama le vai e fai ai le isopropylidene acetone. Fegalegaleai ma le sodium hypobromite e maua ai le 2-hydroxyisovaleric acid. Catalytic hydrogenation gaosia 2-methyl-2,4-pentanediol.
4. O lenei oloa e faʻafefe ai mata, paʻu ma mucous membranes o le manava. E ulu atu i totonu o le tino e ala i le manava ma le digestive tracts, e aʻafia ai le neura ma faʻaleagaina ai le ate ma le manava. O le inhalation o le maualuga maualuga o le ausa e mafai ona fausia ai le edema pulmonary ma e oʻo lava i le koma. O le faʻaalia umi e mafai ona oʻo atu ai i le dermatitis.
5. Maua i le taoina o tapaa, tapaa ivi papa'e, tapaa manogi, ma le asu sikaleti.
Talosaga o Mea:
1.Diacetone alcohol e mafai ona faʻaaogaina e avea o se faʻamama uʻamea, faʻasao fafie, faʻasao mo ata tifaga ma vailaʻau, antifreeze, solvent mo vai faʻafefe, extractant ma fiber finish agent.
2.Diacetone ava malosi o loʻo faʻaaogaina lautele e avea o se solvent mo paʻu eletise eletise, celluloid, nitrocellulose, gaʻo, suauu, waxes ma resins. O le 'ava malosi o le diacetone ose so'o fa'apalapala maualuga. O le viscosity e maualalo ma o le aafiaga o le vevela i le viscosity e laʻititi. Fa'aaogaina e pei o le solvent ma le vali vali mo vali ester cellulose, vaitusi lolomi, vali resini gaosia ma isi.
3.Widely faʻaaogaina e avea o se solvent mo resins, paʻu eletise eletise, celluloid, fibre nitro, gaʻo, suauu ma waxes. E fa'aaogaina fo'i e pei o le fa'amama u'amea, fa'asao fafie, fa'asao mo ata tifaga ma vaila'au, fa'ama'iisaisa, suau'u suau'u fa'asuavai, mea fa'apipi'i ma fiber fa'auma sui. O se ituaiga fo'i fa'atasiga fa'ale-aganu'u.
4.Cosmetic solvent, e masani ona faʻaaogaina e pei o fao fao ma isi mea faʻalelei o le mea faʻafefe maualuga. E masani ona faʻapipiʻiina i soʻomea faʻapalapala maualalo ma mea faʻapipiʻi faʻapipiʻi i totonu o solvents fefiloi, ina ia maua ai le fua faatatau evaporation talafeagai ma le viscosity.
Oloa Teuina Faamatalaga:
1. Teu i totonu ose faleteuoloa malulu, fa'aalili.
2. Taofi ese mai le afi ma le vevela, aloese mai le susulu o le la.
3. Faamau le koneteina.
4.It e le corrosive i uʻamea, ma e mafai ona teuina i uʻamea, uamea vaivai po o koneteina alumini, ae o loʻo i ai se aafiaga erosive i le tele o ituaiga o palasitika.
5. Teu ma felauaiga i fafo mai oxidizing agents ma acids.
6. pakete u'amea po'o fagu tioata o lo'o fa'apipi'iina i mea fa'apipi'i pusa laupapa.
