ʻAikika Formic physicochemical substance

ʻO ka waika formic physicochemical,
ʻAka Formic, Mea Hana Waiwai Formic, Kumukuai ʻAka Formic, Mea Hoʻolako ʻAka Formic,

Kaʻina hana

Hana mākouʻAka Formice ka Methyl Formate kiʻekiʻe loa

ʻenehana.ʻO ka mea mua, hana ʻia ka Methyl Formate mai CO a me Methanol me ka hana o ka catalyst.Ma lalo o kekahi mahana a me ke kaomi, ua hydrolyzed ka Methyl Formate i Formic Acid.ʻO ka hoʻomaʻemaʻe haʻahaʻa Formic Acidsolution e hoʻopili ʻia i nā mea kiʻekiʻe e hoʻokō i nā koi like ʻole-

nā mea kūʻai aku.

Hoʻohālikelike ʻia: HCOOCH3+H2O HCOOH+CH3OH Hoʻohua

7. ʻO nā mea ʻē aʻe: Hiki iā ia ke hana i ka paʻi ʻana a me ke kala ʻana i ka mordant.Coloring

a me ka mea hoʻopau no ka Fiber a me ka pepa, Plasticizer, Food freshkeeping, Feed additive, etc

8. E hana ana i ka cO:Hui kemika: HCOOH=(H mānoanoa, So4catalyze) wela=CO+H，O

9.Deoxidizer: E ho'āʻo e like me ，Bi，Al，Cu，Au，Im,Fe,Pb, Mn, Hg ，Mo，Ag,Zn, etc.Test Ce, Re, Wo.Test aromatic primary amine, secondary amine.dis- mea hoʻoheheʻe no ka hoʻāʻo ʻana i ka molecular WT a me ka crystallization.E hoʻāʻo i ka methoxyl.

10.Fix-er for microscopic analysis.Producing formate.chemical cleaningagent, Formic acid he manuahi ka CL, hiki ke hoʻohana no ka hoʻomaʻemaʻe ʻana i nā mea hana stainlesssteel.

Hiki ke ahi.Hiki ke hoʻopili ʻia me ka wai, ethanol, ether a me glycerol, a me ka hapa nui o nā mea hoʻoheheʻe polar, a loaʻa pū kekahi solubility i nā hydrocarbons.

ʻO ka mānoanoa pili (d204) he 1.220.Hōʻike hōʻike

1.3714.ʻO ka wela wela he 254.4 kJ/mol, ʻo ka wela koʻikoʻi he 306.8 ℃, a ʻo ke kaomi koʻikoʻi he 8.63 MPa.Ke kiko uila 68.9 ℃ (ke kīʻaha hāmama).Māmā 1.22, mānoanoa mahu pili 1.59 (ea =1), kaomi mahu māhu (24 ℃) 5.33kPa.

ʻO ka nui o ka waika formic e maloʻo i ka hoʻoilo.

ʻO nā pūhui i pāpā ʻia: oxidant ikaika, alkali ikaika, pauka metala ikaika.

ʻO nā hiʻohiʻona weliweli: ʻo ka mahu a me ka ea e hana i kahi hui pahū, kahi e hoʻopau ai a pahū i ke ahi ākea a me ka ikehu wela kiʻekiʻe.Hoʻopili pū me nā mea ʻokikene ikaika.

Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia me ka wai, hiki ʻole ke hoʻoheheʻe ʻia i loko o ka hydrocarbons, hiki ke komo i loko o ka waiʻona.

I loko o ka hydrocarbons a me ke kinoea mokuʻāina, puka ka waika formic ma ke ʻano he dimer i hoʻopaʻa ʻia e nā paʻa hydrogen.Ma ke kinoea, hoʻopaʻa hydrogen ka hopena ma waena o ke kinoea ʻakika formic a me ka hoʻohālikelike kinoea maikaʻi o ka mokuʻāina.ʻO ka wai a me ka waika formic paʻa he mau molekala formic acid mau i hoʻopaʻa ʻia e nā paʻa hydrogen.

Hoʻoheheʻe ʻia ka ʻakika Formic i CO a me H2O ma lalo o ka catalysis o ka sulfuric acid concentrated:

Ma muli o ke ʻano kūikawā o ka waika formic, ua pili pololei kekahi o kāna mau hydrogen i ka hui carboxyl.A i ʻole hiki iā ʻoe ke nānā iā ia he hydroxyformaldehyde.No laila, loaʻa i ka ʻakika formic nā waiwai ʻelua a me nā waiwai aldehyde.

Ua like ka waiwai o ka waika formic me ka nui o na waika carboxylic e ae, oiai nae ma ke ano ma'amau, aole i hana ka waika formic i acyl chloride a i ole anhydride.Hoʻoheheʻe ka wai maloʻo i ka waika formic i carbon monoxide a me ka wai.ʻO ka waika Formic ka waiwai hoʻohaʻahaʻa like me nā aldehydes.Hiki iā ia ke hoʻomaka i kahi pane aniani kālā, e hōʻemi ana i nā ion kālā i loko o nā kinikona paʻakikī ammonia kālā i metala kālā, a ua hoʻoheheʻe ʻia ʻo ia i kalapona a me ka wai:

ʻO ka waika Formic wale nō ka waikawa carboxylic hiki ke hoʻohui ʻia i nā olefins.ʻO ka waika Formic i ka hana ʻana o nā ʻakika (e like me ka sulfuric acid, hydrofluoric acid), a me nā olefins e hana koke i nā formates.Eia nō naʻe, hiki ke hana ʻia kahi hopena ʻaoʻao e like me ka hopena Koch, me ka huahana he ʻakika carboxylic kiʻekiʻe.

Maikaʻi paʻa o ka octanol/wai ʻāpana ʻāpana: -0.54, ka palena pahū luna % (V/V): 57.0, ka palena pahū haʻahaʻa % (V/V): 18.0.

ʻO ka waika Formic kahi mea hoʻemi ikaika a hiki i ka hopena aniani kālā ke hiki mai.ʻO ia ka ʻakika loa i loko o nā ʻakika momona saturated, a ʻo ka dissociation mau ʻo 2.1 × 10-4.Wehe malie ia i carbon monoxide a me ka wai ma ka lumi wela.Ua wela ia i 60 ~ 80 ℃ me ka sulfuric acid concentrated e decompose a hoʻokuʻu i ka carbon monoxide.Ke hoʻomehana ʻia ka waika formic ma luna o 160 ° C, hoʻoheheʻe ia e hoʻokuʻu i ka carbon dioxide a me ka hydrogen.Hoʻomaʻamaʻa ʻia nā paʻakai metala alkali o ka formic acid i 400 ° C e hana i nā oxalates.
