TimapangaFormic Acidndi Methyl Formate wapamwamba kwambiri

luso. Choyamba, Methyl Formate amapangidwa kuchokera ku CO ndi Methanolwith zochita za chothandizira. Pansi pa kutentha ndi kupanikizika kwina, Methyl Formate imapangidwa ndi hydrolyzed kukhala Formic Acid. Low purity Formic Acidsolution idzakhazikika kwa apamwamba kuti akwaniritse zofunikira zosiyanasiyana-

makasitomala.

10.Fix-er for microscopic analysis.Kupanga formate.chemical cleaningagent, Formic acid alibe CL, angagwiritsidwe ntchito kuyeretsa zipangizo zosapanga dzimbiri.

Zoyaka. Zitha kukhala miscible ndi madzi, Mowa, etha ndi glycerol, ndi zambiri polar organic solvents, komanso ali ndi solubility zina mu hydrocarbon.

Kachulukidwe wachibale (d204) ndi 1.220. Refractive index

1.3714. Kutentha kwamoto ndi 254.4 kJ / mol, kutentha kwakukulu ndi 306.8 ℃, ndipo kupanikizika kwakukulu ndi 8.63 MPa. Kung'anima mfundo 68.9 ℃ (chikho lotseguka). Kachulukidwe 1.22, kachulukidwe ka nthunzi 1.59 (mpweya = 1), kuthamanga kwa nthunzi (24 ℃) 5.33kPa.

Kuchuluka kwa formic acid kumaundana m'nyengo yozizira.

Mankhwala oletsedwa: oxidant wamphamvu, alkali wamphamvu, ufa wachitsulo wogwira ntchito.

Makhalidwe owopsa: mpweya ndi mpweya zimapanga chisakanizo chophulika, chomwe chimayambitsa kuyaka ndi kuphulika ngati moto wotseguka ndi kutentha kwakukulu. Imakhudzidwa ndi ma okosijeni amphamvu.

Kusungunuka: kusakanikirana ndi madzi, kosasungunuka mu ma hydrocarbons, kusakanikirana ndi mowa.

Mu hydrocarbons ndi gaseous states, formic acid imapezeka ngati dimers omangidwa ndi hydrogen bond. Munthawi ya mpweya, kugwirizana kwa haidrojeni kumabweretsa kupatuka kwakukulu pakati pa gasi wa formic acid ndi ma equation abwino a gasi. Madzi amadzimadzi ndi olimba a formic acid amakhala ndi mamolekyu osalekeza a formic acid omwe amamangidwa ndi ma hydrogen bond.

Formic acid imawola kukhala CO ndi H2O pansi pa catalysis ya sulfuric acid yokhazikika:

Chifukwa cha mapangidwe apadera a formic acid, imodzi mwa maatomu ake a haidrojeni imalumikizidwa mwachindunji ndi gulu la carboxyl. Kapena mutha kuwona ngati hydroxyformaldehyde. Chifukwa chake formic acid imakhala ndi asidi ndi aldehyde.

Formic acid ili ndi zinthu zofanana ndi zina zambiri za carboxylic acid, ngakhale kuti nthawi zonse formic acid sapanga acyl chloride kapena anhydride. Kutaya madzi m'thupi kumawola formic acid kukhala carbon monoxide ndi madzi. Formic acid ili ndi zochepetsera zofanana ndi ma aldehydes. Itha kuyambitsa mawonekedwe a galasi lasiliva, kuchepetsa ayoni asiliva mu ma ion ammonia asiliva kukhala chitsulo chasiliva, ndipo iwowo amapangidwa kukhala carbon dioxide ndi madzi:

Formic acid ndiye carboxylic acid yokhayo yomwe imatha kuwonjezeredwa ku olefins. Formic acid mu zochita za zidulo (monga sulfuric acid, hydrofluoric acid), ndi olefins zimachita mwachangu kupanga mawonekedwe. Komabe, kuchitapo kanthu kofanana ndi kachitidwe ka Koch kumatha kuchitika, pomwe mankhwalawo amakhala okwera kwambiri a carboxylic acid.

Mtengo wa octanol/gawo logawa madzi: -0.54, malire a kuphulika kwapamwamba % (V/V) : 57.0, malire ophulika apansi % (V/V): 18.0.

Formic acid ndi amphamvu kuchepetsa wothandizila ndi siliva galasi anachita. Ndiwo acidic kwambiri mumafuta odzaza mafuta, ndipo dissociation yokhazikika ndi 2.1 × 10-4. Pang'onopang'ono amaphwanyidwa kukhala carbon monoxide ndi madzi kutentha kutentha. Imatenthedwa mpaka 60 ~ 80 ℃ yokhala ndi sulfuric acid yokhazikika kuti iwononge ndikutulutsa mpweya wa monoxide. Formic acid ikatenthedwa pamwamba pa 160 ° C, imawola ndikutulutsa mpweya woipa ndi haidrojeni. Mafuta amchere amchere a formic acid amatenthedwa mpaka 400 ° C kuti apange oxalates.
