Butyraldehyde (CAS # 123-72-8)

Intangiriro

imiterere yimiti

Amazi adafite ibara ryaka umuriro hamwe nimpumuro ya aldehyde. Gushonga buhoro mumazi. Ntibisanzwe hamwe na Ethanol, ether, Ethyl acetate, acetone, toluene, andi mashanyarazi atandukanye hamwe namavuta.

Koresha

Ikoreshwa muri synthesis organic nibikoresho fatizo byo gukora ibirungo

Koresha

GB 2760-96 yerekana ibirungo biribwa byemewe gukoreshwa. Ahanini bikoreshwa mugutegura ibitoki, karamel nibindi biryoha byimbuto.

Koresha

butyraldehyde ni intera ikomeye. n-butanol irashobora kubyazwa umusaruro na hydrogenation ya n-butanal; 2-Ethylhexanol irashobora kubyazwa umusaruro wa dehidrasi ya condensation hanyuma hydrogenation, na n-butanol na 2-Ethylhexanol nibikoresho fatizo byingenzi bya plasitiki. aside n-butyric irashobora kubyara okiside ya aside n-butyric; trimethylolpropane irashobora kubyazwa umusaruro hamwe na fordehide, ikaba ari plasitike ya synthesis ya alkyd resin hamwe nibikoresho fatizo byamavuta yumisha ikirere; kwegeranya hamwe na fenol kugirango ikore amavuta-soluble resin; kondegene hamwe na urea irashobora kubyara alcool-soluble resin; ibicuruzwa byegeranye n'inzoga za polyvinyl, butylamine, thiourea, diphenylguanidine cyangwa methyl karbamate ni ibikoresho fatizo kandi, guhuza hamwe na alcool zitandukanye bikoreshwa nk'umuti wa selile, resin, reberi n'ibicuruzwa bya farumasi; uruganda rwa farumasi rukoreshwa mugukora "Mianerton", "pyrimethamine", na amylamide.

Koresha

Rubber glue, yihuta ya reberi, resin estetique, gukora aside butyric, nibindi. Igisubizo cyayo cya hexane ni reagent yo kumenya ozone. Ikoreshwa nk'umuti wa lipide, ikoreshwa kandi mugutegura uburyohe n'impumuro nziza kandi ikingira.

Uburyo bwo gukora

kuri ubu, uburyo bwo gukora butyraldehyde bukoresha uburyo bukurikira: 1. propylene carboneyl synthesis uburyo bwa propylene na gaze ya synthesis ikora reaction ya carboneyl imbere ya catalizike ya Co cyangwa Rh kugirango itange n-butyraldehyde na isobutyraldehyde. Bitewe na catalizator zitandukanye hamwe nuburyo bukoreshwa, birashobora kugabanywamo synthesis yumuvuduko mwinshi wa karubone hamwe na cobalt carboneyl nka catalizator hamwe na synthesis ya carboneyl hamwe na rhodium carboneyl fosifine nka catalizator. Uburyo bwumuvuduko mwinshi bufite umuvuduko mwinshi hamwe nibicuruzwa byinshi, bityo byongera igiciro cyumusaruro. Uburyo bwa carboneyl synthesis yumuvuduko muke bifite umuvuduko muke wa reaction, igipimo cyiza cya isomer cya 8-10: 1, ibicuruzwa bitari bike, igipimo kinini cyo guhindura, ibikoresho bike, gukoresha ingufu nke, ibikoresho byoroshye, inzira ngufi, byerekana ingaruka nziza mubukungu kandi iterambere ryihuse. 2. Uburyo bwa acetaldehyde. 3. Uburyo bwa Butanol oxyde dehydrogenation bukoresha ifeza nka catalizator, kandi butanol ihindurwamo umwuka mukirere kimwe, hanyuma reaction ikaregeranya, igatandukana, kandi igakosorwa kugirango ibone ibicuruzwa byarangiye.

Uburyo bwo gukora

Iraboneka mugukata byumye bya calcium butyrate na calcium ikora.

Umwuka uboneka na dehydrogenation ya catalizator.
