Nhanganyaya

formic acid) imvura isina ruvara uye inonhuwa. Izvi zvinotevera zvinhu zvikuru zve formic acid:

 

Physical properties: Formic acid inonyanya kunyungudika uye inonyungudika mumvura uye yakawanda organic solvents.

 

Chemical properties: Formic acid inhengo inoderedza iyo inonyoreswa nyore nyore kucarbon dioxide nemvura. Mushonga wacho unopindirana nehwaro hwakasimba kuti ugadzire fomu.

 

Iko kushandiswa kukuru kwe formic acid ndeiyi inotevera:

 

Semishonga inouraya utachiona uye inochengetedza, formic acid inogona kushandiswa mukugadzira dhayi nematehwe.

 

Formic acid inogona zvakare kushandiswa seaizi yekunyungudusa uye muurayi we mite.

 

Pane nzira mbiri huru dzekugadzirira formic acid:

 

Nzira yechinyakare: Distillation nzira yekugadzira formic acid nechidimbu oxidation yehuni.

 

Nzira yemazuva ano: formic acid inogadzirwa ne methanol oxidation.

 

Chengetedzo yekushandiswa zvakachengeteka kwe formic acid ndeiyi inotevera:

 

Formic acid ine kunhuwa kunhuhwirira uye inoparadza zvinhu, saka unofanirwa kupfeka magirovhosi ekudzivirira nemagirazi paunenge uchiishandisa.

 

Dzivisa kufemesa formic acid mhute kana guruva, uye chengetedza mhepo yakanaka paunenge uchishandisa.

 

Formic acid inogona kukonzera kupisa uye inofanira kuchengetwa kure nemoto uye zvinhu zvinobvira.
