Nzira dzekugadzira: 1, neutralization ye formic acid uye hydrated lime kuti ibudise calcium formate, yakanatswa kuti iwane yekutengesa calcium formate.2, kuparara kwechidimbu che sodium formate uye calcium nitrate muhupo hwekugadzirisa kuwana calcium formate, kubatanidzwa kwe sodium nitrate.
Nzira yekugadzira:
1. Neutralization nzira
Formic acid inoderedzwa ne hydrated lime kuti ibudise calcium formate, uye yekutengesa calcium formate inowanikwa nekunatsa.
2. Compound decomposition method
Muhupo hwechigadziriso, sodium formate uye calcium nitrate inopinda kaviri decomposition reaction kuti iwane calcium formate uye inogadzirisa sodium nitrate. Commercial calcium formate yakawanikwa nekunatswa.
3. Ne-chigadzirwa nzira ye epoxy fatty acid methyl ester
Kugadzirwa kwe epoxy fatty acid methyl ester inokura nekukurumidza, uye huwandu hukuru hwe-chigadzirwa formic acid inogadzirwa mukugadzira maitiro. Chimwe chezvirongwa zvekushandisa zveiyi-chigadzirwa formic acid kugadzira calcium formate.
4. Nzira yekuzvarwa nayo
Mukugadzira, calcium hydroxide inoshandiswa kupa mamiriro ekutanga maitiro, uye formic acid inowedzerwa mune inotevera reaction uye calcium hydroxide neutralization process panguva imwe chete kugadzira calcium formate.
Formic acid is carboxylic acid inogona kuwedzerwa kune olefins.Formic acid mukuita kweasidhi (senge sulfuric acid, hydrofluoric acid), uye olefins inokurumidza kuita kuti iite mafomu. Nekudaro, kuita kwepadivi kwakafanana nekuita kweKoch kunogonawo kuitika, nechigadzirwa chiri chepamusoro carboxylic acid.
Pair value ye octanol/water partition coefficient: -, yekumusoro kuputika muganho % (V/V) :, yakaderera kuputika muganhu % (V/V) :.
Formic acid ndeye yakasimba yekudzikisa mumiriri uye sirivheri girazi reaction inogona kuitika. Asidhi mu saturated fatty acids, iyo dissociation inogara iripo×10-4. Inoputsika zvishoma nezvishoma kuita kabhoni monoxide uye mvura pane tembiricha yekamuri. Iyo inopisa kusvika ku60 ~ 80℃ine concentrated sulfuric acid kuti iparadze uye ibudise kabhoni monoxide. Kana formic acid ichipisa kupfuura 160° C, inoora kuti ibudise kabhoni dhaikisaidhi nehydrogen. Iyo alkali simbi yemunyu yefomic acid inodziya kusvika ku400° C kugadzira oxalates.
Inoshandiswa mukuvaka. Inokurumidza kuseta agent, lubricant uye yekutanga simba mumiriri we simende. Inoshandiswa mukuvaka dhaka nekongiri yakasiyana-siyana, kurumidza kuomesa simiti, kupfupisa nguva yekuisa, kunyanya mukuvaka kwechando, kudzivirira kuderera kwekushisa kwekumisa kukurumidza kunonoka. Fast demoulding, kuitira kuti simende nokukurumidza sezvinobvira kuvandudza simba kuisa mukushandisa. Calcium formate inoshandisa: marudzi ese edhaka rakaomarara musanganiswa, marudzi ese ekongiri, zvinhu zvinopfekwa, indasitiri yepasi, indasitiri yezvekudya, kusukuta.Calcium formate uwandu hwekutora chikamu uye chenjedzo Huwandu hwedhaka rakaoma nekongiri patani inenge ~%, uye huwandu hwekuwedzera i%. Huwandu hwecalcium formate hunowedzerwa zvishoma nezvishoma nekudzikira kwetembiricha, kunyangwe huwandu hwe0.3-% hukaiswa muzhizha, hucharidza yakakosha simba rekutanga.
Kana ichipisa, sodium formate inoputsika kuita hydrogen uye sodium oxalate, iyo inobva yagadzira sodium carbonate. Sodium formate inonyanya kushandiswa mukugadzira inishuwarenzi hupfu, oxalic acid uye formic acid. Muindasitiri yematehwe, inoshandiswa seasidhi mune chromium tanning process, secatalyst uye inodzikamisa synthetic agent, uye sechinhu chinoderedza muindasitiri yekudhinda nekudhaya. Sodium formate haina ngozi kumuviri wemunhu uye inogona kutsamwisa maziso, kufema system uye ganda.
