Umkhiqizi Intengo Enhle I-Triphenylmethane i-isocyanate emithathu (isixazululo se-ethyl acetate) I-CAS: 141-78-6 Uhlobo: Desmodur_RE

1. I-ethyl acetate isetshenziswa njengesinyibilikisi sama-varnish, ama-lacquer, kanye ne-nitrocellulose; njengokunambitheka kwezithelo okwenziwa; ekuhlanzeni izindwangu; kanye nasekukhiqizweni kwesilika yokwenziwa kanye nesikhumba, amakha, kanye namafilimu ezithombe kanye namapuleti (Merck 1996). I-ethyl acetate ngokuvamile isetshenziswa njengesinyibilikisi ekuphenduleni kwezinto eziphilayo. Izinto ezingcolisayo zemvelo; Izinto ezingcolisayo zokudla.

2. I-ethyl acetate isetshenziswa ngokuyinhloko njengesinyibilikisi kanye nesixubisi, ithandwa ngenxa yezindleko zayo eziphansi, ubuthi obuphansi, kanye nephunga elimnandi. Isibonelo, ivame ukusetshenziswa ukuhlanza amabhodi wesekethe kanye nakwezinye izisusa ze-nail varnish (i-acetone ne-acetonitrile nazo ziyasetshenziswa). Ubhontshisi wekhofi namaqabunga etiye angena-caffeine ngalesi sinyibilikisi. Iphinde isetshenziswe kupende njenge-activator noma i-hardenener.[Kudingeka ukucashunwa] I-ethyl acetate ikhona kuma-confectionery, amakha, kanye nezithelo. Kumakha, iyahwamuka ngokushesha, ishiye iphunga lekhambi esikhumbeni kuphela.
3 – 1 - Ukusetshenziswa kwelebhu
Elabhorethri, izingxube eziqukethe i-ethyl acetate zivame ukusetshenziswa ku-chromatography yekholomu kanye nokukhipha. I-ethyl acetate ayikhethwa kakhulu njenge-reaction solvent ngoba ithambekele eku-hydrolysis kanye ne-trans esterification.
3 – 2 - Ukuvela kwamawayini
I-ethyl acetate iyi-ester evame kakhulu ewayinini, njengoba ingumkhiqizo we-volatile organic acid evame kakhulu — i-acetic acid, kanye ne-ethyl alcohol ekhiqizwa ngesikhathi sokubilisa. Iphunga le-ethyl acetate likhanya kakhulu emawayinini amancane futhi lisiza ekuboneni "ukuthela izithelo" ewayinini.
3 – 3 - Isidakamizwa sokubulala izinambuzane
Emkhakheni we-entomology, i-ethyl acetate iyi-asphyxiant ephumelelayo yokusetshenziswa ekuqoqweni nasekufundweni kwezinambuzane. Ebhodweni lokubulala eligcwele i-ethyl acetate, umhwamuko uzobulala isinambuzane esiqoqiwe (ngokuvamile esikhulile) ngokushesha ngaphandle kokusibhubhisa. Ngenxa yokuthi asiyi-hygroscopic, i-ethyl acetate igcina isinambuzane sithambile ngokwanele ukuvumela ukufakwa okufanele kuqoqwe.

3. Usizo lwemithi (ukunambitheka); izinto zokwenziwa zezithelo; isixazululo se-nitrocellulose, ama-varnish, ama-lacquer, nama-airplane dopes; ukwenziwa kwempuphu engenantuthu, isikhumba sokwenziwa, amafilimu ezithombe namapuleti, usilika wokwenziwa, amakha; izindwangu zokuhlanza, njll.
