Inqubo

SiyakhiqizaI-Formic Acidnge-Methyl Formate ethuthuke kakhulu

ubuchwepheshe. Okokuqala, i-Methyl Formate ikhiqizwa yi-CO ne-Methanolwith isenzo se-catalyst. Ngaphansi kwezinga lokushisa elithile nokucindezela, i-Methyl Formate igaywa nge-hydrolyzed ibe yi-Formic Acid. Ukuhlanzeka okuphansi kwe-Formic Acidsolution kuzogxilwa kweziphakeme ukuze kuhlangatshezwane nezidingo ezahlukene-

amakhasimende.

Okuvutha umlilo. Ingaxubana namanzi, i-ethanol, i-ether ne-glycerol, kanye nezinyibilikisi eziningi ze-polar eziphilayo, futhi ibe nokuncibilika okuthile kuma-hydrocarbon.

Ukuminyana kwesihlobo (d204) kungu-1.220. Inkomba ye-refractive

1.3714. Ukushisa komlilo kungu-254.4 kJ/mol, izinga lokushisa elibalulekile lingu-306.8 ℃, futhi ukucindezela okubalulekile ngu-8.63 MPa. Iphoyinti le-Flash 68.9 ℃ (inkomishi evuliwe). Ukuminyana 1.22, ukuminyana komhwamuko okuhlobene 1.59 (umoya =1), ukucindezela komhwamuko ogcwele (24℃) 5.33kPa.

Ukugxila okuphezulu kwe-formic acid kuvame ukuba yiqhwa ebusika.

Izinhlanganisela ezingavunyelwe: i-oxidant enamandla, i-alkali enamandla, impushana yensimbi esebenzayo.

Izici eziyingozi: umhwamuko nomoya kwakha ingxube eqhumayo, ebangela ukusha nokuqhuma uma kuba nomlilo ovulekile namandla okushisa aphezulu. Isabela nama-oxidants aqinile.

Ukuncibilika: kuxubene namanzi, akuncibiliki kuma-hydrocarbon, kuxubene otshwaleni.

Kuma-hydrocarbons nasezifundeni ezinegesi, i-formic acid yenzeka njengama-dimers aboshwe ngamabhondi e-hydrogen. Esimeni segesi, i-hydrogen bonding iholela ekuphambukeni okukhulu phakathi kwegesi ye-formic acid kanye ne-equation yegesi efanelekile yendawo. Uketshezi kanye ne-solid formic acid iqukethe ama-molecule e-formic acid eqhubekayo aboshwe ngamabhondi e-hydrogen.

I-Formic acid ibola ibe yi-CO ne-H2O ngaphansi kwe-catalysis ye-concentrated sulfuric acid:

Ngenxa yesakhiwo esikhethekile se-formic acid, enye yama-athomu ayo e-hydrogen ixhumeke ngokuqondile eqenjini le-carboxyl. Noma ungayibuka njenge-hydroxyformaldehyde. Ngakho-ke, i-formic acid inezinto zombili ze-asidi ne-aldehyde.

I-asidi ye-formic inezinto ezifanayo njengamanye ama-carboxylic acid amaningi, nakuba ngaphansi kwezimo ezijwayelekile i-asidi ye-formic ayenzi i-acyl chloride noma i-anhydride. Ukuphelelwa amanzi emzimbeni kubola i-formic acid ibe yi-carbon monoxide namanzi. I-Formic acid inezinto zokunciphisa ezifanayo kuma-aldehydes. Ingakwazi ukuqalisa ukusabela kwesibuko esisiliva, inciphise ama-ion esiliva ku-ion esiliva ye-ammonia ibe insimbi eyisiliva, futhi yona ngokwayo ifakwe i-carbon dioxide namanzi:

I-Formic acid iyona kuphela i-carboxylic acid engezwa kuma-olefin. I-Formic acid esenzweni sama-asidi (njenge-sulfuric acid, i-hydrofluoric acid), nama-olefin asabela ngokushesha ukuze akhe amafomu. Kodwa-ke, ukusabela okuseceleni okufana nokusabela kwe-Koch nakho kungenzeka, ngomkhiqizo ongaphezulu kwe-carboxylic acid.

Ivelu yokubhanqa ye-octanol/i-partition ye-coefficient yamanzi: -0.54, umkhawulo wokuqhuma okuphezulu % (V/V) : 57.0, umkhawulo wokuqhuma ophansi % (V/V) : 18.0.

I-Formic acid iyi-ejenti yokunciphisa enamandla futhi ukusabela kwesibuko esisiliva kungenzeka. I-acidic kakhulu ku-saturated fatty acids, futhi i-dissociation constant yi-2.1 × 10-4. Iqhekeka kancane ibe yi-carbon monoxide namanzi asezingeni lokushisa elijwayelekile. Ishiselwa ku-60~80℃ nge-concentrated sulfuric acid ukuze ibole futhi ikhulule i-carbon monoxide. Uma i-formic acid ishisa ngaphezu kuka-160 ° C, iyabola ukuze ikhiphe i-carbon dioxide ne-hydrogen. Usawoti wensimbi we-alkali we-formic acid ushiselwa ku-400 ° C ukuze akhe ama-oxalate.
