Peb feem ntau npaj los tsim kev sib raug zoo ntev thiab ruaj khov nrog txhua tus neeg yuav khoom hauv cov teb cuam tshuam.













1. Txoj Cai ntawm Kev Ua Tshwm Sim:
Cov pa roj carbon monoxide (CO) ua rau cov tshuaj sodium hydroxide (NaOH) ntawm 160–200°C thiab 2 MPa siab los ua sodium formate (HCOONa). Cov khoom no ces raug acidolyzed nrog sulfuric acid thiab distilled kom tau txais formic acid ua cov khoom kawg.
2. Cov Lus Piav Qhia Txog Kev Ua Haujlwm:
Cov txheej txheem no siv coke ua cov khoom siv raw, uas dhau los ntawm kev ua roj, tshem tawm plua plav, ntxuav, decarbonization, thiab ntxiv kev ntxuav kom tau txais cov pa roj carbon monoxide (CO) uas xav tau. Tom qab ntawd CO raug cua sov, nias, thiab cuam tshuam nrog sodium hydroxide los tsim cov tshuaj sodium formate, uas tom qab ntawd tau evaporated, sib cais, thiab ziab kom tau cov khoom sodium formate khov.
