Chikamu Chechina: Kushandiswa
Ammonium Formate (HCOONH4) CAS: 540-69-2 inogona kushandiswa muindasitiri yemishonga kana kushandiswa seanalytical reagents.
Chikamu Cheshanu: Ungachiwana sei
1. Yakatorwa kubva kune neutralization ye formic acid uye ammonia. Isai iyo formic acid nemvura, simbisai ammonia gasi kuita kuti pH kukosha ive 7-7.5, dzikisa tembiricha kusvika -5â uye spin-sefa kuti uiwane.
2. Mune 90% formic acid solution, pfuura ammonia gasi.
Mushure mekunge huwandu hwakakwana hweammonia gasi hwaunzwa, tembiricha inokwira uye kupisa kunoburitswa kunogona kukurudzira kunaya kwayo. Makristasi acho akapepetwa, akagadziridzwa kubva kune absolute ethanol, uye akaomeswa mune vacuum desiccator ine 99% sulfuric acid.
3. 100 zvikamu zve methyl formate, 100 zvikamu zvemvura, 0.1 chikamu che formic acid, gadzirisa pH kusvika 2.5, kupisa kusvika 70 ° C nekukurudzira, kuwedzera 20 zvikamu zveammonia mvura, chengetedza pH pa 2 ~ 3, mushure mechinguva. 1h, 70% formic acid Iyo methyl ester yakave hydrolyzed. Internal steaming inoitwa. Kana tembiricha yemusoro we distillation iri 10 ° C, isina kubatwa methyl formate uye methanol inobviswa, ichisiya ine acidic solution yayo mu evaporator. Neutralize neammonia uye bvisa zvakare kuti uiwane ne98% yemukati
