Chigadzirwa Zita:Ethyl acetate

Molecular Fomati:C4h8o2

CAT HAPANA:141-78-6

Chigadzirwa Molecular chimiro:

Zvemakemikari zvivakwa:

Ethyl Acetate (chimiro chinoratidzwa pamusoro) ndiyo inozivikanwa ester kune vazhinji vekemikistry vadzidzi uye vangangoita ester neyakawedzera mashandisiro ekushandisa. Esters yakarongedzwa zvakarongeka kubva kuCarboxyllic acids nekutsiva iyo acidic hydrogen neAlkyl kana ARYL GROUP. Ethyl acetate pachayo ndeye isina ruvara mvura pamhepo tembiricha ine inonakidza "kunhuhwirira, bp 77 ° C.

Ethyl Acetate ine zvakawanda zvinoshandiswa, zvakadai sechibereko chekunyepedzera uye chinonhuwira zvekunhuhwirira, zvine miti yakawanda kugadzirwa kwekudhinda inks uye zvinonhuhwirira.

Chikumbiro:

Ethyl acetate inoshandiswa zvakanyanya se solvent uye duliuent, kuve inofarirwa nekuda kwemutengo wayo wakaderera, uye nekunhuhwirira kwakadzika. Semuenzaniso, zvinowanzoshandiswa kuchenesa mabhodhi ematunhu uye mune mamwe zvipikiri zvipikiri zvinopfura (aceton uye acetonitrile zvinoshandiswawo). Bhinzi yekofi uye tii mashizha anogadziriswa neiyi solvent zvakare mune pendi semutambi kana kuomesa. [Kuongorora kunodiwa] Mune zvinonhuhwirira, inobuda nekukurumidza, ichisiya kunhuhwirira kwezvinonhuwira paganda.
3 - 1 - Rabhoritari Inoshandisa
MuBabhoritari, musanganiswa une ethyl acetate zvinowanzoshandiswa muColumn chromato edzidzo uye kuwedzerwa. Ethyl Acetate haawanzo kusarudzwa seyakagadziriswa solvent nekuti inowanzoita hydrolysis uye trans estation.
3 - 2 - kuitika mumasaini
Etiral Acetate ndiyo yakajairika ester in the waini, kuve chigadzirwa cheanonyanya kujairika organic acid - acetic acid, uye iyo ethyl doro rakagadzirwa panguva yekufemerwa. Kunhuhwirira kweTevyl Acetate kwakanyanya kujeka mumasaini madiki uye kunobatsira kune iwo maonero e "chibereko" muwaini.
3 - 3 - Instological Kuuraya Mumiriri
Mumunda weIntomology, Ethyl Acetate ndeye Aspaphyxiant inoshanda yekushandisa muchidimbu kuunganidza uye kudzidza. Mukuuraya chirongo chakabhadharwa neEthyl acetate, maVapris anouraya akaunganidzwa (kazhinji munhu mukuru) nekukurumidza pasina kukuparadza. Nekuti haisi hygroscopic, ethyl acetate zvakare inochengeta zvipembenene zvakapfava zvakakwana kuti ubvume kukwenya kwakakodzera kuti uunganidzwe.
