Umvelisi ofanelekileyo kwi-Therihenylmenete yesithathu (i-Ethyl Acetate) I-CASS: 141-78-6 Brand: Desmoodur_re

Inkcazo emfutshane:

I-organic ye-organic kunye nefomula ch3coch2C3. I-Ethyl Acetate isisombululo se-allue engenabala iphunga elinemifanekiso (efana nepere) kwaye isetyenziswa kwi-glues, isikhonkwane, kunye nekofu kunye necuba, jonga uluhlu lweekomiti kwicuba). Isisombululo se-Ethyl Acetate sisisombululo se-ethanol kunye ne-acetic acid; Isisombululo se-Ethyl Acetate senziwe kwinqanaba elikhulu lokusetyenziswa njengesinyibilikisi. Imveliso yonyaka edibeneyo ngo-1985 yeJapan, iMantla Melika, naseYurophu yayimalunga nama-400,000 eetoni. Ngo-2004, iitoni ze-1.3m zenziwa kwihlabathi liphela.

Izicelo

I-1.thyl Acetate isetyenziswa njengenyibilikisi yevarnies, i-lacquers, kunye neNitrocellulose; njengokucofa i-incause yeziqhamo. ekuhlambululeni izitayile; kwaye ekwenzeni ukwenziwa kwe-articieather, iziqholo, kunye neefilimu zefonti (i-Merck 1996). I-Ethyl Acetate isetyenziswa njengesinyibilikisi kwi-solvent yokuphendula. Ukungalawulwa kokusingqongileyo; Ukutya okungcolileyo.

I-2thyl Acetate isetyenziselwa ikakhulu njengenyibilikisi kwaye inyani, ithandelwe ngenxa yeendleko zayo eziphantsi, ityhefu ephantsi kakhulu, kunye ne-odor enobuchule. Umzekelo, iqhelekile isetyenziselwa ukucoca iibhodi zesekethe kwaye kwezinye izipikili zangaphantsi (i-acetone kunye ne-acetotirle ziyasetyenziswa). Iimbotyi zekofu kunye namagqabi iti zidibaniwe kunye ne-solvent.it ikwasetyenziswa kwi-paints njengeyona nto ifunekayo kwi-confetate, iziqholo kunye neziqhamo. Kwiziqholo, iyaphula ngokukhawuleza, ishiya kuphela ivumba lesiqholo kulusu.
I-3-1-I-Laboratri isebenzisa
Elabhoratri, imixube equkethe i-ethyl acetate isetyenziswa kwikholamu yekholamu kunye nokukhutshwa. I-Ethyl Acetate ayifane ikhethwe njengenkqubo yokuphendula ngenxa yokuba iqhelekile kwi-hydrolysis kunye ne-trans standation.
I-3-2 - YAYIKHONA
I-Ethyl Acetate yeyona nto ixhaphakileyo kwi wayini, ukuba yimveliso ye-acid exhaphakileyo exhaphakileyo ye-Acid - i-acetic acid, kunye notywala obutyhilo lwe-gathyl luvelisiwe ngexesha lokubiyela. Ivumba le-icetate licace kakhulu kwiiwayini ezincinci kwaye linegalelo ekuqondeni ngokubanzi 'kokuziswa "kwi wayini.
I-3-3 - i-entomological arhente
Kwicandelo le-ettomology, i-ethyl i-ethyl yi-asphyxiant esebenzayo ukuba isetyenziswe kwi-insect yokuqokelela nokufunda. Kwi-jar yokutsala i-Ethyl Acetate, iimpuphu ziya kubulala i-themed (ihlala inesinambuzane) ngaphandle kokutshabalalisa. Kuba ayisiyo hygroscopic, i-Ethyl Acetate nayo igcina inambuzane ithambile ngokwaneleyo ukuvumela ukuphakanyiswa okufanelekileyo kufanelekile ukuba ingqokelela.

I-3.pharmarmarmarmarutic noncedo (i-flavor); Iziqhamo zeziqhamo zokufakelwa; I-Solvent yeNitrocellulose, i-Varnish, i-lacquers, kunye neenqwelomoya; ukwenziwa komgubo ongatshayiyo, isikhumba esingesosikhumba, iifilimu kunye neepleyiti, isilika yokufakelwa, iziqholo; Ukucoca izibalo, njl.
