Inkqubo
SivelisaFormic Acidngeyona iphambili iMethyl Formate
iteknoloji. Okokuqala, i-Methyl Formate iveliswa kwi-CO kunye ne-Methanolwith isenzo se-catalyst. Phantsi kobushushu obuthile kunye noxinzelelo, iMethyl Formate ifakwa emanziniFormic Acid. Ukucoceka okuphantsi kwe-Formic Acidsolution kuya kugxininiswa kwiindawo eziphezulu ukuhlangabezana neemfuno ezahlukeneyo-
izinto zabathengi.

Ukutsha. Iyakwazi ukuxutywa ngamanzi, i-ethanol, i-ether kunye ne-glycerol, kunye neninzi ye-solvents ye-polar organic, kwaye ine-solubility ethile kwi-hydrocarbons.
Ubuninzi bobuninzi (d204) yi-1.220. Isalathiso sokuqhafaza
1.3714. Ukushisa okuvuthayo ngu-254.4 kJ / mol, ukushisa okubalulekileyo ngu-306.8 ℃, kunye noxinzelelo olunzima ngu-8.63 MPa. Indawo edanyazayo 68.9 ℃ (indebe evulekileyo). Uxinaniso 1.22, ukuxinana komphunga 1.59 (umoya =1), uxinzelelo lomphunga ogcweleyo (24℃) 5.33kPa.
Uxinzelelo oluphezulu lwe-asidi ye-formic luthanda ukuba ngumkhenkce ebusika.
Iikhompawundi ezingavumelekanga: i-oxidant eyomeleleyo, i-alkali enamandla, umgubo wesinyithi osebenzayo.
Iimpawu ezinobungozi: umphunga kunye nomoya zenza umxube oqhumayo, obangela ukutsha kunye nokudubula kwimeko yomlilo ovulekileyo kunye namandla okushisa aphezulu. Isebenza kunye nee-oxidants ezinamandla.
Ukunyibilika: kuxubene namanzi, akunyibiliki kwiihydrocarbons, kuxubene etywaleni.
Kwii-hydrocarbons kunye ne-gaseous states, i-asidi ye-formic ivela njenge-dimers eziboshwe ngeebhondi ze-hydrogen. Kwimeko yegesi, ukudityaniswa kwehydrogen kukhokelela kunxaxhi olukhulu phakathi kwerhasi yefomic acid kunye nerhasi efanelekileyo equation yelizwe. Ulwelo kunye ne-slid formic acid iqulethe iimolekyuli ze-asidi yefomi eqhubekayo edityaniswe ziibhondi ze-hydrogen.
I-asidi ye-formic ibolile ibe yi-CO kunye ne-H2O phantsi kwe-catalysis ye-asidi ye-sulfuric concentrated:
Ngenxa yesakhiwo esikhethekileyo se-asidi ye-formic, enye yee-athom zayo ze-hydrogen ziqhagamshelwe ngokuthe ngqo kwiqela le-carboxyl. Okanye unokuyibona njengehydroxyformaldehyde. Ngaloo ndlela i-asidi ye-formic inezo zombini iimpawu ze-asidi kunye ne-aldehyde.
I-asidi ye-formic ineempawu ezifanayo kunye nezinye i-carboxylic acids ezininzi, nangona phantsi kweemeko eziqhelekileyo i-asidi ye-formic ayifaki i-acyl chloride okanye i-anhydride. Ukuphelelwa ngamanzi emzimbeni kutshabalalisa i-asidi ye-formic kwi-carbon monoxide kunye namanzi. I-asidi ye-formic ineempawu ezifanayo zokunciphisa kwi-aldehydes. Inokuqalisa ukusabela kwesipili sesilivere, inciphisa i-ion zesilivere kwi-amonia yesilivere ye-ammonia ukuya kwisinyithi sesilivere, kwaye yona ngokwayo ifakwe kwi-carbon dioxide kunye namanzi:
I-asidi ye-Formic kuphela kwe-asidi ye-carboxylic enokongezwa kwi-olefins. I-asidi ye-formic kwisenzo se-acids (njenge-asidi ye-sulfuric, i-hydrofluoric acid), kunye ne-olefins zisabela ngokukhawuleza ukwenza iifomathi. Nangona kunjalo, ukusabela okusecaleni okufana nempendulo ye-Koch kunokwenzeka, kunye nemveliso ibe yi-carboxylic acid ephezulu.
Ixabiso lesibini le-octanol/i-coefficient ye-partition coefficient: -0.54, umda wokudubula okuphezulu % (V/V) : 57.0, umda wokudubula osezantsi % (V/V): 18.0.
I-asidi ye-formic yi-arhente yokunciphisa eyomeleleyo kunye nempendulo yesipili sesilivere ingenzeka. Yeyona acidic kakhulu kwi-fatty acids acids, kwaye i-dissociation constant yi-2.1 × 10-4. Ngokucothayo iqhekeka ibe yicarbon monoxide namanzi akwiqondo lobushushu begumbi. Ifudunyezwa kwi-60 ~ 80℃ kunye ne-asidi yesulfuric egxininisiweyo ukubola kunye nokukhulula i-carbon monoxide. Xa i-asidi ye-formic ishushu ngaphezu kwe-160 ° C, iyabola ukuze ikhuphe i-carbon dioxide kunye ne-hydrogen. Iityuwa zesinyithi ze-alkali ze-formic acid zifudunyezwa kwi-400 ° C ukwenza i-oxalates.
