Icrystalline calcium ifomathi yolusu lwesikhumba

Indlela yokuvelisa:

1. Indlela yokungathathi hlangothi

Formic acid ayithatyathwe nge-hydrated lime ukuvelisa i-calcium formate, kwaye i-calcium formate yorhwebo ifunyanwa ngokusulungekiswa.

2. Indlela yokubola komdibaniso

Phambi kwe-catalyst, i-sodium formate kunye ne-nitrate ye-calcium ifumana impendulo yokubola kabini ukufumana i-calcium formate kunye nokuvelisa i-nitrate ye-sodium. Ifomati ye-calcium yorhwebo yafunyanwa ngokucokiswa.

3. Indlela yemveliso ye-epoxy fatty acid methyl ester

Ukuveliswa kwe-epoxy fatty acid methyl ester ikhula ngokukhawuleza, kwaye isixa esikhulu se-asidi ye-formic yemveliso iveliswa kwinkqubo yokuvelisa. Esinye sezicwangciso zokusetyenziswa kwale mveliso ye-asidi ye-asidi kukuvelisa i-calcium formate.

4. Indlela yokuzalwa

Kwinkqubo yokuvelisa, i-calcium hydroxide isetyenziselwa ukubonelela ngeemeko zokuphendula ezisisiseko, kwaye i-asidi ye-formic yongezwa kwi-reaction elandelayo kunye nenkqubo ye-calcium hydroxide neutralization ngexesha elifanayo ukuvelisa i-calcium formate.

I-asidi ye-Formic yi-asidi ye-carboxylic enokongezwa kwi-olefins.Formic acid 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 elidityanisiweyo le-octanol/i-coefficient yolwahlulo lwamanzi: -, umda wokudubula okuphezulu % (V/V) :, umda osezantsi wokudubula % (V/V) :.

I-asidi ye-formic yi-arhente yokunciphisa eyomeleleyo kunye nempendulo yesipili sesilivere ingenzeka. I-Acidic kwi-saturated fatty acids, i-dissociation constant is×10-4. Ngokucothayo iqhekeka ibe yicarbon monoxide namanzi akwiqondo lobushushu begumbi. Ifudunyezwa ukuya kuma-60~80℃kunye ne-asidi yesulfuric egxininisiweyo yokubola kunye nokukhulula i-carbon monoxide. Xa i-asidi ye-formic ifudunyezwa ngaphezu kwe-160° C, iyabola ukuze ikhuphe ikharbon diokside kunye nehydrogen. Iityuwa zesinyithi zealkali zefomiic acid zifudumeza ukuya kuma-400° C ukwenza i-oxalates.

Isetyenziswa kwi-architecture. I-ejenti yokuseta ngokukhawuleza, i-lubricant kunye ne-arhente yamandla yangethuba kwisamente. Isetyenziswe kwisakhiwo sodaka kunye nekhonkrithi eyahlukeneyo, khawuleza isantya sokuqina kwesamente, unciphise ixesha lokumisa, ngakumbi kulwakhiwo lwasebusika, ukuphepha isantya sokumisa ubushushu obuphantsi bucotha kakhulu. Ukudilizwa ngokukhawuleza, ukuze isamente ngokukhawuleza kunokwenzeka ukuphucula amandla asetyenziswe. Ukusetyenziswa kwefomati yeCalcium: zonke iintlobo zodaka oluxubeneyo olomileyo, zonke iintlobo zekhonkrithi, izixhobo ezinganxibiyo, ishishini lomgangatho, ishishini lokutya, ukusukwa.Ifomati yecalcium Isixa sentatho-nxaxheba kunye nezilumkiso Ubungakanani bodaka olomileyo kunye nekhonkrithi ngetoni nganye malunga ne- ~%, kwaye isixa-mali esongezelelweyo yi-%. Isixa se-calcium formate sinyuswa kancinci kancinci ngokuhla kweqondo lobushushu, nokuba isixa se-0.3-% sisetyenziswa ehlotyeni, siya kudlala isiphumo samandla sakwangoko.

Xa ishushu, i-sodium fomati iqhekeka ibe yi-hydrogen kunye ne-sodium oxalate, ethi emva koko yenze i-sodium carbonate. I-sodium formate isetyenziswa kakhulu kwimveliso yomgubo we-inshurensi, i-oxalic acid kunye ne-asidi ye-formic. Kwishishini lesikhumba, lisetyenziswa njenge-asidi kwinkqubo yokutshisa i-chromium, njenge-catalyst kunye nokuzinzisa i-agent synthetic, kunye ne-arhente yokunciphisa kwishishini lokuprinta kunye nokudaya. I-sodium formate ayinabungozi emzimbeni womntu kwaye inokucaphukisa amehlo, inkqubo yokuphefumla kunye nolusu.
