organicum Esther compositis

Ethyl Acetate est organicum estens compositum cum formula hypothetica C4H8O2 (vulgo abbreviata ut EtOAc vel EA), sicut liquidum sine colore apparet. Valde miscibilia cum omnibus communibus solventibus organicis (alcoholis, ketones, glycols; esters), quae commune solvendo ad purgandum, fucum remotionem faciunt coatingit.
Ethyl acetas in alcoholicis potionibus, sacrificiis, raphanis, fructibus succos, cerevisiam, vinum, spiritus etc. Fructum habet proprium odoris qui est vulgo in glutinat, clavum nitorem Aufero, tea decaffeinating and capulus, ac hispanas. Ob odorem suavissimum et humile pretium, hoc chemica communiter adhibita et magna in mundo fabricata, ut supra 1 decies centena millia talentorum annuatim.

Purificationis et aquae remotionis modi

Ethyl acetate plerumque habet contentum 95% ad 98% continens parvam quantitatem aquae; ethanol et aceticum aceticum. Purificari potest ut sequenti: 100mL . add anhydridis aceticae in 1000mL acetatis ethyl; addere X guttae acidi sulphurici concentrati, caloris et refluxus 4h ad immunditias removendas ut ethanol et aqua, et postea sub- distillationibus. Distillare est oscillatum per 20~ 30g carbonas potassii anhydroi et ulterioris subjecti re- distillationis. Productum ferveret punctum 77 ° C et puritas super XCIX%.

Productio

Industriae productio ethyl acetatis in tribus processibus maxime indicatur.

Prima classica est processus Fischer esterificationis ethanolicae cum Acidum aceticum in praesentia acidi catalyst. Hic processus requirit acidum catalyst2 ut acidum sulphuricum, acidum hydrochloridum, acidum ptoluene sulfonic mixtura conversis ad Esther circiter 65% cede ad locus temperatus. 
CH3CH2OH + CH3COOH CH3COOC2H5 + H2O
Reactio accelerari potest per catalysin acidum et aequilibrium transfertur ad dextram per remotionem aquae.

Secunda est Tishchenko Reactio acetaldehydi utendi aluminii triethoxide sicut catalyst. In Germania et Iaponia, acetas maxime ethyla est productus per processum Tishchenko. 
2 CH3CHO → CH3COOC2H5
Haec ratio duobus itineribus contendit; (i) dehydrogenative processus, qui cupro vel palladio utitur, catalyst et subnixus (ii) oxidative una, quae utitur, PdO catalysts sustinetur.

Tertia, quae nuper mercatus est, addita acetici est Acidum ethylene argilla et heteroploy acid7 ut catalyst. 
CH2= CH2 + CH3COOH → CH3COOC2H5 
Processus autem quaedam incommoda habent; et conventional esterificatio et additamentum acidi acetici ad ethylene egent lacus et lacus apparatu aliquot lignorum cibarium. Utuntur autem acetico acetico causante apparat corrosionem. Licet Teshchenko Reactio utitur una tantum feed et materia mordax non-est, difficile acetaldehyde tractare, quia extra aream industrialem petrochemicam praesto non est.
Talibus in adiunctis, productio acetatis ethyl melioris processus est vehementer exoptata.

Descriptio

Ethyl acetate (systematice, ethyl ethanoate, vulgo abbreviatum EtOAc vel EA) est the organici compositi cum formula CH3COOCH2CH3. Hoc hyalina liquor habet proprium odoris (similis piro guttae) et in glutinat, clavum nitorem removentes, tea decaffeinating et capulus, ac cigarette (vide Indicem additivorum in Montibus). Ethyl acetate esten ethanol et aceticum; in magnis conficitur ad usum solvendo. Composita productio annua in 1985 Iaponiae, Septentrionalis America, et Europa circiter 400,000 millia talentorum fuit. In 2004, extimationis 1.3M tons productae sunt.

Chemical Properties

Ethyl acetas habet a fruetus aethereus amoenus, odoris sublimatus, pineapple simile; aliquantum nauseam in alta intentione. Fructus dulce saporem, cum recenter aqua dilutum. Ethyl acetas verisimile est unus ex quibus imitandis omnis sapor oeconomiae a volumine. Ethyl acetas tardius resolutum est humorem acquirit et inde statum acidum ob aceticum acidum formatum est.

Corporalis proprietatibus

Clarum, sine colore; mobilis liquor amoeno, suavis fructuoso odore. Experimento determinari deprehensio et agnitio odoris liminis concentratione erant 23 mg/m3 (6.4 ppmv) et 48 mg/m3 (13.3 ppmv); respectively (Hellman and Small, 1974). Cometto-Mu?iz and Cain (1991) nuntiata mediocris acrimonia nasi limen concentratio 67,300 ppmv.

usus

Ethyl acetas primario usus est ut solvens et diluens, propter humilitatem suam sumptus, humilis ebrietas, suavis odor. Verbi gratia, vulgo usurpatur to . mundum circa tabulas et in aliquo clavo illitus auferentes (acetone et acetonitrile quoque usus est). Fabam et folia tea capulus cum decaffeinated hoc solvent.Ita etiam in fucis ut activator vel hardener opus] Ethyl acetas in dulcibus, unguentis, et fructuum. In unguentis cito euanescit, odore tantum relicto unguentum in cute.
3 - 1 - Laboratorium usus
In officina mixturae ethyl acetatis continentur communiter in columnae fina et extractiones. Raro ethyl acetas electa ut a reactionem solvendo, quia prona est ad hydrolysim et trans- esterificationem.
3 - 2 - Occurrentia in vinis
Ethyl acetas niensis in vino frequentior est, quia ex lutulentissimis nascitur commune volatile acidum organicum - aceticum aceticum et ethyl alcohol generatum in fermentum. Odor ethyl acetatis vividissimus in junioribus vino et confert ad communem perceptionem "fructus" in vino. 
3 - 3 - Entomologica occisio agentis
In campo entomologiae ethyl acetas asphyxians efficax est ad usum in insecto colligendis et studendis. In cado ethylo accusatus acetas; vapores collectas interficiet (plerumque adultum) sine cito animal delendum. Quia hygroscopicum non est, ethyl acetas etiam custodit insectum molle satis est, ut adscendens aptam collectionem propriis concedas.

usus

Ethyl acetas solver pro varnis, lacqueribus, et nitrocellulosis; as fructus saporis anartificialis; Purgato textorum et in armorum of artificialis sericum andleather, unguentum, et laminae photographicae membranae (Merck 1996).

usus

Auxilia pharmaceutica (flavor); fructus essentiae artificialis; solventibus nitrocellulosis, varnishes; lacquers, scapha dapes; ACAPNOS fabricare pulveris, artificialis corium, membrana photographica et laminae, sericum artificiale, unguenta; Purgato textorum, etc.

Productio Methodi

Ethyl acetas esse potest confici per distillationem tardam mixturam ethanoli et acetici acidi coram acido sulphurico attenti. Etiam ex ethylene utens aluminio alkoxide catalyst.

Productio Methodi

Ethyl acetas summa industria summa via classic Fischer esterification reactio ethanoli et acidi acetici. Haec mixtura convertitur ad Esther in de LXV% cede ad locus temperatus:
CH3CH2OH + CH3COOH ? CH3COOCH2CH3 + H2O
Reactio accelerari potest per catalysin acidum et aequilibrium transfertur ad dextram per remotionem aquae. Etiam in industria paratur per reactionem Tishchenko, iungendo duo adumbrari acetaldehyde coram alkoxide catalyst:
2 CH3CHO → CH3COOCH2CH3.

Praeparatio

Ethyl acetas facta per æstimationem acidi acetici cum ethanolo, ab acetaldehyde, seu by de ethylene directo ad aceticum acidum. BP incepit 220,000 tonne/annum in 2001 plantum novissimum horum processuum agunt, qui notus est AVADA. Ethylene et acidum aceticum agere coram heteropolyacid sedibus dare ethyl acetate ad petita alta selectivity et 99,97% pudicitiam. Haec est maxima ethyl acetatis mundi planta et moveatur eius usus crescens ut plus "accepti" solvendo quam hydrocarbonum.
In nonnullis regionibus, ubi ethanol carus est vel superfluum est acetaldehyde capacitas, ethyl acetas facta per reactionem Tishchenko. Sasol in Africa Australi dicebatur talem processum in primis investigare 2000s. Ethanol solvens est superficiei coatingis, praeparationibus purgandis, et uterentur. Industriae ethanolum aerobically fermentatum est album vinegar (Acidum aceticum dilutum) generis usus ad servantur. COMEDUS aceta-vinum acetum, cider acetum, et sic porro, per fermentationem alcoholici potiones-sunt etiam available. Decem cento productionis ethanoli industrialis acetum in Civitatibus Foederatis in MMI adhibitum est.

Reactiones

Ethyl acetas esse potest hydrolyzata in conditionibus acidicis vel basics ad aceticum aceticum et ethanolum reducendum. Usus acidi catalysti hydrolysin accelerat, quae subiecta est de aequilibrio Fischer, de quo supra. In elit ac usitas for tantum proposita illustrativa, ethyl esters typice hydrolyzed in duobus gradus processus incipiens a moles stoichiometrica basi fortis, ut sodium. Haec reactio dat ethanolum et sodium acetatem, quae est ethanol praeservatum in unreactive;
CH3CO2C2H5 + Na OH → C2H5OH + CH3CO2Na
Rate constans est 0.111 dm3 / mol.sec in 25 °C.
