Txoj Kev Siv Gas-Theem Formic Acid

Txoj kev siv roj-theem yog ib txoj hauv kev tshiab dua rau kev tsim cov kua qaub formic. Cov txheej txheem ntws yog raws li nram no:

 

(1) Kev Npaj Khoom Siv Raw:

Methanol thiab huab cua raug npaj, nrog rau methanol raug ntxuav thiab qhuav.

 

(2) Kev Tshuaj Xyuas Oxidation ntawm Theem Gas:

Methanol uas tau kho ua ntej lawm yuav ua rau cov pa oxygen sib xyaws ua ke thaum muaj cov tshuaj catalyst, ua rau muaj formaldehyde thiab cov pa dej.

 

(3) Cov tshuaj tiv thaiv kua-theem catalytic:

Formaldehyde ntxiv mus catalytic hloov pauv mus rau hauv formic acid hauv cov kua-theem tshuaj tiv thaiv.

 

(4) Kev Sib Cais thiab Kev Ntxuav:

Cov khoom lag luam tshuaj tiv thaiv raug sib cais thiab ntxuav siv cov txheej txheem xws li distillation lossis crystallization.

Cov lus hais luv nqi ntawm Formic acid txij lub Yim Hli mus txog rau lub Kaum Hli, nyem qhov no kom tau txais nws.
