usus

Benzaldehyde adhibetur sicut mediumin productione condiendi oeconomiae, ut cinnamaldehyde, cinnamalalcohol, et amyl- et hexylcinnamldehyde pro unguentum, sapo, et cibus sapor; synthetica penicillin, ampicillin et ephedrine; et sicut araw materia pro herbicide Vindice. Itoccurs in natura in seminibus amygdalarum, persicorum, cerasorum, persicorum. Occurrit intrace sextaria frumenti olei.

usus

Tincturae fabricare; unguentaria, acida cinnamica et mandelica solvendo; in saporibus.

usus

Benzaldehyde est a CONDITIO agentis, quod est liquidum et sine colore, et habet odorem amygdalinum. is calidum (ardentem) saporem habet. benzoic acidum expositum est oxidized aer et corrumpitur sub luce. miscibile est in oleis volatilibus, fixis olea, aetheris, alcohol; est in aqua spar- lorum solutum. fit per synthesin chemica et naturali eventui in oleis amygdalae amarae; persici et nucleum persicum. item benzoic aldehyde nuncupatur.

Definition

A flavo organicum oleum distincto amygdalae odoris. Benzenecarbaldehyde motus subit proprium aldehydes et in officina perstringi potest usitatis modis synthesin aldehyde. Ponitur in cibo condito et in tincturarum et antibioticorum fabrica, et facile confici potest de chlorinatione methylbenzene et hydrolysi subsequentis benzene: C6H5CH3 + Cl2 →C6H5CHCl2 C6H5CHCl2 + 2H2O →C6H5CH(OH)2+ 2HCl C6H5CH(OH)2  →C6H5CHO + H2O.

General Description

Patet hyalina to flavus liquor cum amaro amygdali odore. Mico punctum circa 145°F. Densior quam aqua et insolubilis in aqua. Hinc mergitur aqua. Vapores graviores sunt quam aer. Periculum primarium est ambitus. Immediata gradus sit capta ad circumscribere propagationem ad environment. Facile solo penetrat contaminare groundwater ac prope rivi. Usus in condito et unguento faciendi.

Aer & aqua Reactiones

Oxidizes in aere to formant acidum benzoicum, quod mediocriter toxicum per ingestionem est. Insolubilis in aquam.

Reactividad Profile

A nontoxic, liquor combustibilis, cum reagentia oxidizing reflectitur. Benzaldehyde oportet omni tempore cum Benzaldehyde est oxidized in gas iners stratum libenter ex aere ad acidum benzoicum [Kirk-Othmer, 3rd ed., vol. III, 1978, p. 736]. In contactu cum validis acida vel basibus Benzaldehyde exothermica subibit condensatio reactio [Sax, 9th ed., 1996, p. 327]. A vehementi reactionem est observata in contactu cum peroxyacidis (acidi peroxyformici) [DiAns, J. et al. Ber., 1915, 48, p. 1136]. Explosio facta est cum pyrrolidine; Benzaldehyde et acidum propionicum calefactum ad formandum porphyrinum.

Periculum salutis

Benzaldehyde exhibetur humili ad moderandam toxicityin experimento animalium, veneficii effectdepending dosis. Ingestio 50-60 mLmay hominibus perniciosa erit. Oral attractio largedose potest tremorem facere, dolor gastrointestinalis et renibus damno. Animalia experimenta indicantur quod ingestion of this compoundby Guineae sues tremorem, sanguinem ex intestino parvo, et augmentum urinae Volumen, in mures inclusi somnolenceand coma effecit.
Valor LD50, oralis (Guineae porcorum): 1000 mg/kg
Valor LD50, oralis (mures): 1300 mg/kg
A D-mg moles ad XXIV-hora periodresulted in mediocri cute irritatio in Lepores.Because toxicity humilis, altum ferveret, humilis vapor pressura, salubria hominibus a nuditate ad benzaldehydeis valde humilis.

Ignis Discrimen

FLAMMABILIS: A calore, scintillae vel flammae facile accendentur. Vapores formare potest explosive mixtura aeris. Vapores ad fontem ignitionis et retro micare possunt. Plurimi vapores aere graviores sunt. Expandent per humum et collect in humilibus vel angustiis ( cloacas, basements, lacus). Vapor explosio aleam intus, foris, vel cloacis. Runoff cloaca ut creare ignem vel CREPITUS aleam. Vasa calefacta explodere possunt. Multi liquores leviores sunt aquam.

Synthesis chemica

Natural benzaldehyde obtinetur per extractionem et subsequentem fracti distillationis ex fontes botanici; synthetically, a benzyl chloride et calcis vel by oxidatio toluene

Potentialis expositio

In officinis unguenta, tincturas, acetum cinnamicum; quasi solvendo; in saporibus.

repono

Benzaldehyde debet conservari in arcte clauso vase et munitum contra physicam damno. Repono substantiae chemica extra aut in area detracta est malle, cum intus in repositione liquores flammabiles vexillum esse debere cella vel scrinium. Benzaldehyde separari debet ab oxidizing materiae. Item, repositio et usus arearum fumigantium arearum non debent esse. Continentes de hac materia periculosum esse potest, cum vacuum sit, cum productum retineat residua (vapor, liquidus); omnia monita et cautiones enumerantur factum

Purificationis Methodi

Ad minuendam suam rate oxidationis, benzaldehydae plerumque continet additiva ut hydroquinone vel catechol. Purgari potest per bisulfitum suum adiectionem compositi, sed plerumque distillationis (sub nitrogen ad pressuram reducta) satis est. Ante to distillation lavatur cum NaOH vel X% Na2CO3 (donec amplius CO2 is evolvitur), dein saturatis Na2SO3 et H2O, dein exsiccatis cum CaSO4; MgSO4 vel CaCl2. [Beilstein 7 IV 505.]
