Description

Furfural est renewable essential, non PETROLEUM-fundatur, praesertim is, qui ex variis eget feedstock agriculturae byproducts, inter oat siliquis, triticum furfures, corncobs et SCOBIS. Chemica, quae in aldehyde compositum organicum furfural est ex odore furan in amygdalas deformati sunt. Quod est typically industriae produci ob proposita, quae potest esse sicut electionem selectivam, solvendo est in processus conflans olea et lubricating exercendis armorum officinis usus est ut amplio translationem fuels Diesel fuel et proprietates catalytic cracker redivivus strinxit ligno. Praeter, est late in producendo furfural resina infecto, religata continent abrasive butadiene opus rotae purificavit umbra exercendis armorum officinis synthetica rubber. Et factum est, ut solebat alias furan aquis alchimicis, sicut acidum et furoic furan ipsum. Other products includit in furfural interfectorem viriditas, fungicide, et aliis mediis solventibus etc.

Description

Furfural electri, velut pinguis umor est sine colore est quasi in nucis modum per odoris suavissimi componendum. Aspirante luce caeli ferrugineae evenit. Furfural quod facis in aquis alchimicis, sicut nariae PETROLEUM conflans, et fungicide, viriditas, et ad interfectorem. Repugnat enim fortem acida, oxidisers et alcalia validus. Contactus cum extra Polymerisation non est fortis et fortis alcalia acida. Fit per commercium acido Furfural hydrolysa pentosan polysaccharides cibum non ex residua edulia ligna consumit. Hoc est late usus est, qui menstrui in PETROLEUM conflans, phenolic et resinam proposuerunt in productio, et aliud in variis applications. Accidit in humanis furfural proferendo expositione uti ex multis res naturales cibi et carbones combustione lignorum.

Properties eget

hyalinae vel rufo-brunneis oleum fluidi odor amygdalus, impinguabitur locusta

Properties eget

Sine colore flavo est aromaticum, ut Furfural het cum erocyclic aldehyde quasi in nucis modum odoris suavissimi componendum. Lux et aer alternis aspirante electri.

Properties eget

Furfural perspicax natura est divinum odorem spirare. De sacrificiis quae in pentosans Furfural paratur industrially Bruns et avenae; haec sunt materiae digeri ante est adeo dilutos esse H2S04 et fumus generatur per sublimationem furfural formatae.

Properties eget

Perspicax natura est typical of cyclic aldehydes Furfural suavitatis.

Spermatophyta

Sine colore flavo est quasi in nucis modum per fluidi odor. Rufescit, brunneis aspirante et lucem caeli. Odor illi saporque et IV 0.4 sunt superliminaria: ppm, respectively (allata sunt, ut et Thomas, MCMXCII). Shaw et al. (MCMLXX) relata LXXX aquam in limine ad gustum ppm.

usibus

In armorum officinis furfural phenol plastics, sicut Durite; uritur in solvendo petroleum unguento Acidum pyromucic ad parandum. Ut a solvendo pro nitrated bombacio, Cellulose acetate, dentem atque russam defricare; Varnishes in armorum officinis; vulcanization ad accelerato; et Insecta, fungicide, germicide; tenui literature quod sunt analytica. In synthesim doctrinae furan derivationes.

Ratio purificatione

Furfural obvenit instabile est, ut aer, lux atque acida. Formic acid includit immundis:. Et acidum-formylacrylic furan-II-acid. Fluat et in balneum oleum de VII% (w / w) Na2CO3 (checked corrumpebant acida, acidum maxime pyromucic). Redistil est a II% (w / w) Na2CO3 et tum tandem, fluat fractionally sub ea vacuo movebitur. Non conditur in tenebras. [Lat Cham Indos Friedrich Kritz & Evans (ed ani) XXIV 1926. XVIII] Impurities ab inde remota ab repono posse iter ulli per gradus chromatographic ALUMEN. Furfural potest separari a sordibus suis Revolutionibus componit quam carbonyl bisulfite etiam in compositis. A aldehyde vapor est volatile. Non autem per destillationem per illam purificatus (Claisen usus capite) sub pressura reducitur. Quod maximi est momenti est ut usum olei lotus est non altius quam cum temperaturis 130o, quae enixe commendantur. Atmosphaerae pressura generatur per sublimationem a cum furfural (iaceant in flumine, et N2 Tandem explosa), vel reducitur sub pressura flammae et libera (cavendum est, quia fomes aldehyde), et oleum, hyalinis, adeptus est. Paucis post diebus, et interdum a paucis horis et ut ei paulatim oleum involvens et tandem fit nigrum. Hoc lumen fit per mutationem acceleratum tardius cum posita sit in medio brunneis utrem. Sed cum in vacuo generatur per sublimationem aldehyde et balneum temperatus 130o infra tenentur per destillationem, et oleum modice develops expositae, cum color directam sunlight per dies aliquot. Non debet esse nimis immundorum destillationem adgressus aeris vis materialis; aliter ab ipso cursim productum tenebrescit. Postquam autem per destillationem vacui a distillation peragi possint in atmosphaericae pressionis sunt sine compositione et nigrantem nimis. Liquor mucosae concitet. Condite in vasis in tenebris N2 Tandem explosa, obsignatorum completam praesertim per ampoules. [Org Synth Voorhees Adams & Media MCMXLI CCLXXX Volume I: 292 V Beilstein 17/9]
