Umenzi weXabiso eliLungileyo I-Triphenylmethane emithathu isocyanate(isisombululo se-acetate ye-ethyl) CAS: 141-78-6 Brand: Desmodur_RE

I-1.I-ethyl acetate isetyenziswa njenge-solvent ye-varnishes, i-lacquers, kunye ne-nitrocellulose; njengencasa yeziqhamo ezingaqhelekanga; ekucoceni amalaphu; nasekwenzeni isilika nesikhumba eyenziweyo, iziqholo, kunye neepleyiti zemifanekiso yeefilimu kunye neefoto (Merck 1996). I-Ethyl Acetate isetyenziswa ngokubanzi njenge-solvent kwi-organic reactions. Izinto ezingcolisa indalo; Ungcoliseko lokutya.

I-2.I-acetate ye-Ethyl isetyenziswe ngokuyinhloko njenge-solvent kunye ne-diluent, ithandwa ngenxa yeendleko zayo eziphantsi, i-toxicity ephantsi, kunye nephunga elimnandi. Ngokomzekelo, ngokuqhelekileyo isetyenziselwa ukucoca iibhodi zeesekethe kwaye kwezinye izikhonkwane zokususa i-varnish (i-acetone kunye ne-acetonitrile nazo zisetyenziswa). Iimbotyi zekofu kunye namagqabi eti anecaffeinated kunye nale solvent.Ikwasetyenziswa kwiipeyinti njenge activator okanye i-hardener. Kwiziqholo, iphuma ngokukhawuleza, ishiya kuphela ivumba le-perfume esikhumbeni.
3 – 1 - Ukusetyenziswa kweLebhu
Kwilabhoratri, imixube equkethe i-ethyl acetate isetyenziswa ngokuqhelekileyo kwikholamu yechromatography kunye ne-extractions. I-acetate ye-Ethyl ayifane ikhethwe njenge-solvent yokuphendula ngenxa yokuba ithanda ukuhlanjululwa kwe-hydrolysis kunye ne-trans esterification.
3 – 2 - Ukwenzeka kwiiwayini
I-acetate ye-Ethyl yeyona ester ixhaphakileyo kwiwayini, iyimveliso ye-asidi eguquguqukayo eqhelekileyo - i-acetic acid, kunye ne-ethyl alcohol eyenziwa ngexesha lokuvutshelwa. Ivumba le ethyl acetate licace kakhulu kwi wayini ezincinci kwaye linegalelo kwimbono jikelele "yeziqhamo" kwi wayini.
I-3 - 3 - i-entomological kill agent
Kwinkalo ye-entomology, i-ethyl acetate yi-asphyxiant esebenzayo yokusetyenziswa ekuqokeleleni izinambuzane kunye nokufunda. Kwingqayi yokubulala ehlawuliswe nge-ethyl acetate, umphunga uya kubulala inambuzane eqokelelweyo (ngokuqhelekileyo ikhulile) ngaphandle kokuyitshabalalisa. Ngenxa yokuba ingeyo-hygroscopic, i-ethyl acetate ikwagcina isinambuzane sithambile ngokwaneleyo ukuvumela ukunyuswa okufanelekileyo kulungele ukuqokelela.

3.Uncedo lwamayeza (incasa); iziqhamo ezenziweyo; i-solvent ye-nitrocellulose, i-varnishes, i-lacquers, kunye ne-dopes yendiza; ukwenziwa komgubo ongenamsi, ngethwathwa, iifilim zeefoto kunye neepleyiti, isilika yokwenziwa, iziqholo; ukucoca impahla, njl.
