Formic acid ke e 'ngoe ea lisebelisoa tsa mantlha tsa organic lik'hemik'hale tse tala, tse sebelisoang haholo ho chefo e bolaeang likokoanyana, letlalo, dae, meriana le liindasteri tsa rabara.Asiti ea formic e ka sebelisoa ka kotloloho ts'ebetsong ea masela, letlalo la ho tantša, khatiso ea masela le ho daea le polokelo ea lijo tse tala, hape e ka sebelisoa e le moemeli oa kalafo ea tšepe holim'a tšepe, rabara e thusang le solvent ea indasteri.Ka organic synthesis, e sebelisetsoa ho kopanya lifomate tse fapaneng, lidae tsa acridine le letoto la li-intermediate tsa bongaka tsa formamide.Lihlopha tse khethehileng ke tse latelang:

1. Indasteri ea meriana:

E ka sebelisoa bakeng sa ho sebetsana le caffeine, aminopyrine, aminophylline, theobromine borneol, vithamine B1, metronidazole le mebendazole.

2. indasteri ea chefo:

e ka sebelisoa bakeng sa mafome a phofo, triazolone, tricyclozole, triazole, triazolium, triazolium, polybulozole, tenobulozole, insecticide, dicofol processing.

3. Indasteri ea lik'hemik'hale:

lisebelisoa tse tala bakeng sa ho etsa liforomo tse fapaneng, formamide, pentaerythritol, neopentanediol, oli ea soya ea epoxy, epoxy octyl soybean oleate, valeryl chloride, ho tlosa pente le phenolic resin.

4. indasteri ea letlalo:

e sebelisoa e le litokiso tsa ho suha letlalo, liemeli tsa ho chesoa ha letlalo le li-neutralizing agents.

5. indasteri ea rabara:

bakeng sa ts'ebetso ea li-coagulants tsa tlhaho tsa rabara, tlhahiso ea rabara ea antioxidant.

6. tlhahiso ea laboratori CO. Chemical reaction formula:
