Tau Lelei a le Kamupani Gaosi Triphenylmethane tolu isocyanate (fofo ethyl acetate) CAS: 141-78-6 Fa'ailoga: Desmodur_RE

1. E fa'aaogaina le Ethyl acetate o se vaila'au fa'amamā mo varnishes, lacquers, ma nitrocellulose; o se tofo fuala'au fa'apitoa; i le fa'amamāina o ie; ma i le gaosiga o silika fa'apitoa ma pa'u, mea manogi, ma ata tifaga ma ipu (Merck 1996). E masani ona fa'aaogaina le Ethyl Acetate o se vaila'au fa'amamā i tali fa'alenatura. Mea leaga o le siosiomaga; Mea leaga o mea'ai.

2. O le Ethyl acetate e fa'aaogaina tele o se vaila'au fa'amama ma se vaila'au fa'amama, e fiafia i ai ona o lona taugofie, maualalo le o'ona, ma le manogi manaia. Mo se fa'ata'ita'iga, e masani ona fa'aaogaina e fa'amama ai laupapa eletise ma nisi o vaila'au e aveese ai vali fao (e fa'aaogaina fo'i le acetone ma le acetonitrile). O pi kofe ma lau lauti e aveese le kafeini i lenei vaila'au fa'amama. E fa'aaogaina fo'i i vali o se mea fa'agaoioi po'o se mea fa'ama'a'a. [mana'omia se fa'amatalaga] O le Ethyl acetate o lo'o iai i mea suamalie, mea manogi, ma fuala'au 'aina. I mea manogi, e vave ona mago, ma na'o le manogi o le mea manogi e totoe i le pa'u.
3 – 1 - Fa'aaogāga i le fale su'esu'e
I totonu o le fale su'esu'e, o paluga o lo'o i ai le ethyl acetate e masani ona fa'aaogaina i le chromatography o le koluma ma le fa'amamāina. E seasea filifilia le Ethyl acetate e fai ma vaila'au fa'amama ona e faigofie ona fa'a-hydrolysis ma trans esterification.
3 – 2 - O le iai i uaina
O le Ethyl acetate o le ester sili ona taatele i le uaina, o le oloa lea o le volatile organic acid sili ona taatele - acetic acid, ma le ethyl alcohol e gaosia i le taimi o le fermentation. O le manogi o le ethyl acetate e sili ona manino i uaina talavou ma e fesoasoani i le iloa lautele o le "fua" i le uaina.
3 – 3 - Mea e fasioti ai iniseti
I le matata o le entomology, o le ethyl acetate o se vailaʻau e faʻamama ai le manava mo le faʻaaogaina i le aoina ma le suʻesuʻeina o iniseti. I totonu o se fagu fasioti tagata ua faʻatumuina i le ethyl acetate, o le a vave ona fasiotia e le ausa le iniseti ua aoina (e masani lava o le matua) e aunoa ma le faʻaumatiaina. Talu ai e le hygroscopic, o le ethyl acetate e faʻamalūlūina ai foʻi le iniseti ina ia mafai ai ona faʻapipiʻi lelei mo se aoina.

3. Fesoasoani i vailaʻau (tofo); mea manogi faʻapitoa o fualaʻau; vailaʻau faʻamamā mo le nitrocellulose, varnish, lacquers, ma vailaʻau faʻamamā mo vaʻalele; gaosiga o le pauta e leai se asu, paʻu faʻapitoa, ata tifaga ma ipu ata, silika faʻapitoa, mea manogi; ie faʻamamā, ma isi mea faʻapena.
