Butyraldehyde (CAS#123-72-8)

Hordhac

sifooyinka kiimikada

Dareere gubanaya oo aan midab lahayn oo leh ur aldehyde asphyxiating. Waxoogaa ku milmay biyaha. Isku-dhafan oo leh ethanol, ether, ethyl acetate, acetone, toluene, noocyo kala duwan oo dareerayaasha kale ee dabiiciga ah iyo saliidaha.

Isticmaal

Loo isticmaalo isku-dhafka dabiiciga ah iyo walxo ceeriin ah oo lagu sameeyo uunsiga

Isticmaal

GB 2760-96 wuxuu qeexayaa uunsiga la cuni karo ee loo ogol yahay in la isticmaalo. Inta badan waxaa loo isticmaalaa diyaarinta muuska, karamell iyo khudaarta kale.

Isticmaal

butyraldehyde waa dhexdhexaad muhiim ah. n-butanol waxaa lagu soo saari karaa hydrogenation of n-butanal; 2-ethylhexanol waxaa lagu soo saari karaa fuuqbaxa uumi ka dibna hydrogenation, iyo n-butanol iyo 2-ethylhexanol waa alaabta ceeriin ee ugu weyn ee balaastikada. n-butyric acid waxaa lagu soo saari karaa oksaydhka n-butyric acid; trimethylolpropane waxaa lagu soo saari karaa uumi leh formaldehyde, kaas oo ah balaastiiste loogu talagalay isku dhafka alkyd resin iyo alaabta ceeriin ee saliidda qalajinta hawada; uumi leh phenol si ay u soo saaraan resin saliid-milmi leh; Uumiga leh urea waxay soo saari kartaa xabagta alkohol- milmi; Alaabooyinka lagu shubay alkolada polyvinyl, butylamine, thiourea, diphenylguanidine ama methyl carbamate waa alaabta ceeriin iyo, uumiga leh aalkolo kala duwan ayaa loo isticmaalaa sida dareeraha celluloid, resin, caag iyo alaabta dawooyinka; warshadaha dawooyinka waxaa loo isticmaalaa in lagu sameeyo "Mianerton", "pyrimethamine", iyo amylamide.

Isticmaal

Xabagta caagga ah, xawaaraha caagga ah, ester resin synthetic, butyric acid oo soo saara, iwm. Loo isticmaalo sida dareere loogu talagalay lipids, sidoo kale loo isticmaalo diyaarinta dhadhanka iyo udgoonka iyo sida ilaalinta.

Habka wax soo saarka

Waqtigan xaadirka ah, hababka wax soo saarka ee butyraldehyde waxay qaataan hababka soo socda: 1. Habka propylene carbonyl synthesis propylene iyo gaaska synthesis waxay fuliyaan falcelinta carbonyl synthesis in joogitaanka Co ama Rh kicinta si loo dhaliyo n-butyraldehyde iyo isobutyraldehyde. Sababo la xiriira kicinta kala duwan iyo xaaladaha habka loo isticmaalo, waxa loo qaybin karaa cadaadiska sare ee carbonyl synthesis la cobalt carbonyl sida kicinta iyo cadaadiska hoose ee carbonyl synthesis la rhodium carbonyl phosphine adag sida kicinta. Habka cadaadiska sare wuxuu leeyahay cadaadis sare oo falcelin ah iyo waxyaabo badan oo ka soo baxa, sidaas darteed kordhinta qiimaha wax soo saarka. Habka isku-dhafka carbonyl-ka hooseeya wuxuu leeyahay cadaadis falcelin hooseeya, saamiga isomer-ka togan ee 8-10: 1, wax-soo-saarka yar, heerka beddelka sare, alaabta ceeriin ee hooseeya, isticmaalka tamarta yar, qalabka fudud, habka gaaban, oo muujinaya saameyn dhaqaale oo aad u fiican iyo horumar degdeg ah. 2. Habka uumiga Acetaldehyde. 3. Habka fuuq-baxa ee Butanol waxa ay u isticmaashaa qalin si kaaljiye ah, butanol waxa ay hawo oksidhisay hal tallaabo, ka dibna fal-celiyeyaasha ayaa la isku ururin, la kala saarayaa, lana saxayaa si ay u helaan alaabta dhammaatay.

Habka wax soo saarka

Waxaa lagu helaa qallayl qallalan oo ah kalsiyum butyrate iyo qaabka calcium.

Uumiga waxaa lagu helaa fuuq-baxa kicinta.
