Isingeniso

formic acid) uketshezi olungenambala olunephunga elimnandi. Lokhu okulandelayo yizinto eziyinhloko ze-formic acid:

 

Izakhiwo zomzimba: I-Formic acid incibilika kakhulu futhi inyibilika emanzini kanye nezincibilikisi eziningi eziphilayo.

 

Izici zamakhemikhali: I-Formic acid iyi-ejenti enciphisayo efakwa kalula kwi-carbon dioxide namanzi. Inhlanganisela isabela ngesisekelo esiqinile ukuze ikhiqize ifomethi.

 

Ukusetshenziswa okuyinhloko kwe-formic acid imi kanje:

 

Njengesibulala-magciwane nesilondolozi, i-formic acid ingasetshenziswa ekulungiseni odayi nesikhumba.

 

I-Formic acid ingasetshenziswa futhi njenge-ejenti encibilikisa iqhwa kanye nombulali wezibungu.

 

Kunezindlela ezimbili eziyinhloko zokulungiselela i-formic acid:

 

Indlela yendabuko: Indlela yokukhishwa kwe-distillation yokukhiqiza i-formic acid nge-oxidation yengxenye yokhuni.

 

Indlela yesimanje: i-fomic acid ilungiswa nge-methanol oxidation.

 

Izinyathelo zokuqapha ukusetshenziswa okuphephile kwe-formic acid zimi kanje:

 

I-Formic acid inephunga elimnandi kanye nezakhiwo ezibolayo, ngakho kufanele ugqoke amagilavu ​​okuzivikela kanye nezibuko lapho uyisebenzisa.

 

Gwema ukuhogela umhwamuko we-formic acid noma uthuli, futhi uqinisekise ukungena komoya okuhle uma usebenzisa.

 

I-Formic acid ingabangela ukuvutha futhi kufanele igcinwe kude nomlilo nezinto ezivuthayo.
