Umkhiqizi Intengo Emihle I-Triphenylmenethane ezintathu isocyanate (ethyl acetate solution) Cas: 141-78-6 brand: desmodur_re

Incazelo emfushane:

I-Organic Compact ngeFomula Ch3Cooch2ch3. I-Ethy Acetate Solution Uketshezi olungenamibala lunephunga elimnandi lobuhle (elifana namaconsi ethayini) futhi lisetshenziselwa amaconsi, lisuselwa itiye nekhofi (ukubona ugwayi (nogwayi (bona ugwayi (ubone ugwayi wezithasiselo ku-Cigarete). Isixazululo se-Ethy Acetate singu-Ester we-ethanol ne-acetic acid; kwenziwa isixazululo se-ethyl acetate senziwa ngezinga elikhulu ukuze lisetshenziswe njenge-solvent. Ukukhiqizwa okuhlangene ngonyaka ngo-1985 kweJapan, eNyakatho Melika, naseYurophu kwakungamathani angama-400,000. Ngo-2004, kwakhiqizwa amathani ayi-1.3m emhlabeni wonke.

Izinja

I-1.Ethyl acetate isetshenziswa njenge-solvent yama-varnish, ama-lacquers, ne-nitrocellulose; njengokunambitheka kwezithelo okwenziwe; ekuhlanzeni izindwangu; nasekwenziweni kwesilika kasilika wokufakelwa, amakha, kanye nezithombe zama-filmsland amapuleti (Merck 1996). I-Ethy Acetate ngokuvamile isetshenziswa njenge-solvent ekuphendukeni okuphilayo. Ukungcola kwemvelo; Ukungcola kokudla.

I-2.Ethyl acetate isetshenziswa ngokuyinhloko njenge-solvent kanye ne-dillunt, ethandwa ngenxa yezindleko zayo eziphansi, ubuthi obuphansi nephunga elivumayo. Isibonelo, kuvame ukusetshenziselwa ukuhlanza amabhodi wesifunda futhi kwezinye izipikili ezisusa izipikili (i-acetone ne-acetonitritle nazo zisetshenziswa). Ubhontshisi wekhofi kanye namaqabunga etiye anamaqabunga afakiwe ngale solvent.it nawo asetshenziswa kumapende njengesishoshovu noma i-hartiner. Kumakha amakha, kuyaphuma ngokushesha, kushiya iphunga lamakha esikhunjeni.
3 - 1 - Ukusetshenziswa Kwelabhoratri
Elebhu, ukuhlanganiswa okuqukethe i-ethyl acetate kuvame ukusetshenziswa kwikholamu i-chromatography kanye nokukhishwa. I-Ethyl Acetate ayivamile ikhethwa njenge-solvent yokusabela ngoba ithambekele ku-hydrolysis kanye ne-trans desterication.
I-3 - 2 - isenzakalo ewayini
I-Ethyl Acetate yi-Ester evame kakhulu ewayinini, engumkhiqizo we-organic acid evame kakhulu - i-acetic acid, kanye notshwala be-ethyl elenziwe ngesikhathi sokuvutshelwa. Iphunga le-ethyl acetate licacile kakhulu ewanini lezingane futhi linomthelela ekuboneni okujwayelekile kokuthi "izithelo" ewayinini.
3 - 3 - Umenzeli wokubulala okubonakalayo
Emkhakheni we-Entomology, i-Ethyl Acetate iyi-askyciant ephumelelayo yokusetshenziswa ekuqoqweni kwezinambuzane nokutadisha. Embizeni ebulalayo ekhokhiswa i-ethyl acetate, ama-vapors azobulala abaqoqiwe (imvamisa) izinambuzane ngokushesha ngaphandle kokuzicekela phansi. Ngoba akulona i-hygroscopic, i-ethyl acetate ibuye iqhubeke nezinambuzane ithathe ngokwanele ukuvumela ukufakwa okufanele kufanelekile iqoqo.

Usizo lwe-3.pharmaceutic (ukunambitheka); izithelo zokufakelwa; solvent for nitrocellose, ama-varnish, ama-lacquers, nezindondo zezindiza; Kwenziwa i-powder ebhemayo, isikhumba sokufakelwa, amafilimu wezithombe namapuleti, usilika wokufakelwa, amakha; Ukuhlanza izindwangu, njll.
