Ethyl acetoacetate Synthesis Synthesis

Descriptio	Compositum organicum ethyl acetoacetatum (EAA) est ethyl niensis acidi acetoacetici. Praecipue adhibetur ut medium chemicum in varietate compositorum producenda, ut amino acida, analgesica, antibiotica, agentia antimalaria, antipyrine et amino pyrine et vitaminum B1; necnon fucorum, atramentorum, atramentorum, unguentorum, materiarum, ac flavorum pigmentorum. Solus, pro sapore pro cibo ponitur.
Chemical Properties	Ethyl acetoacetate proprium habet aetherem similem, fructuosum, amoenum, refrigerium odoris.
Chemical Properties	Ethyl 3-Oxobutanoate liquor est hyalinus cum fructuoso , aethereo , suavi odore simile pomorum viridium . Solet creare recentes, frugiferas notas in foemineis suavissimis odoribus. Ethyl acetoacetate contingit in saporibus materiarum naturalium, ut capulus, fraga, et fructus passionis lutei.
Productio Methodi	Ethyl acetoacetate fabricatur per reactionem altae puritatis ethyl acetatis cum sodio, quam sequitur neutralisatio cum acido sulphurico.
Praeparatio	Ethyl acetoacetate industrialiter tractando diketen cum ethanolo nascitur. Praeparatio ethyl acetoacetatis est processus officinarum classicarum. Praeparata per condensationem ethyl acetatis Claisen. Duae talpae ethyl acetatis condensant molam unamquamque ex ethyl acetoacetatis et ethanoli formant.
Aroma limina values	Deprehensio: 520 ppb. Aroma proprietatum ad 10%: pomum dulce pomiferum, fermentatum, leviter fusel-simile et rummy, fixa fructuosa cum nuances tropica.
Gustus limina values	Gustus characteres in 100 ppm: Musa fructuosa, pomi et uvae albae cum estry viridis et tropicae nuances. Taste characteres 300 ppm: esterus, pinguis, fructuosus et tutti-frutti
General Description	A hyalina liquore cum fructu odoris. Flash punctus 185°F. Fervens 365°F. Potest facere adversa valetudo effectus, si ingestum vel attractum. Ad cutem, oculos et membranulas mucosae. Adhibentur organice synthesi et in lacquers et fucis.
Purificationis Methodi	Excutere niensis cum exiguis saturis aqueis NaHCO3 (usque ad nullam ulteriorem effervescentiam), deinde aqua. MgSO4 vel CaCl2 eam excoquatur et eam sub pressione reducat. [Beilstein 3 IV 1528.]
