i-esidi ye-formic, lephindze ibitwe ngekutsi yi-methanoic acid, i-CAS No.64‐18‐6, yi-aliphatic carboxylic esidi lelula kakhulu, lebonakala njengemanti lafutfumalako labonakalako langanambala laneliphunga lelicasulako lelibuhlungu. Ingahlanganiswa ngalokuphelele nemanti, i-ethanol kanye ne-glycerol. I‐formic acid yetfu yesigaba setimboni ifinyelela ku 85% lokuncane, lefaka kwakheka lokucinile kanye nekungcola lokuphansi kwetinsimbi letisindzako, lokube yintfo lebalulekile yemakhemikhali leluhlata yemikhakha yekucubungula sikhumba kanye nerabha.- Emkhakheni wekukhicita sikhumba, i-formic acid isetjentiswa kakhulu ekuphekeni kanye nenchubo yekushukela. Ingalungisa kahle linani le pH ye tjwala bekushisa, ikhutsate kungena kwe tanning agent etikhumbeni tetilwane, kwenta ncono kutsamba kwesikhumba kanye nelizinga letinhlavu. Kukhicitwa kwerabha, isebenta njenge coagulant lesetulu‐lesebenta kahle ye latex yemvelo, kusita kucinisa ludzaka lwe latex kutfola emabhulokhi erabha lafanako lanetinkhomba leticinile temtimba. Ngaphandle kwekusetjentiswa lokungenhla lokuyinhloko, lomkhicito ungasebenta njenge esidi yekuhlanta i-ejenti yekuhlanta indzawo yensimbi, kususa lucwencwe lwe-oxide kanye nekubola etulu ensimbi ngaphambi kwekutsi kusetjentiswe i-electroplating.
- Ludzaka lwetfu lwe-formic acid lupakishwa esigubhini sepulasitiki lesingu 25kg, esigubhuni sepulasitiki lesingu 250kg noma ethangini le-IBC lekutfunyelwa elwandle. Njengekhemikhali leyingoti legugako, onkhe emaphakheji ahambisana ngalokuphelele nelizinga lekutfumela timphahla letiyingoti te-UN. Njalo licembu litawuhlolwa endlini ngaphambi kwekuletsa, umbhalo we-COA uyatfolakala ngesicelo semtsengi. Siphakela imitfwalo lemikhulu yetindzawo tekushuka, emafemu erabha kanye nebatsengisi bemakhemikhali emhlabeni wonkhe. Kwemukela batsengi labaphesheya kwetilwandle kutsi babute ngentsengo ye-FOB, umthamo wekulayisha kanye nemibhalo yekutfumela ngaphandle kwe-oda lenyenti.
