He mura ahi. Ka taea te miscible ki te wai, te waiwaro, te etera me te glycerol, me te nuinga o nga whakarewa pararopi polar, me te mea he whakarewatanga kei roto i te waiwaro.

Ko te kiato whanaunga (d204) he 1.220. Taupū Refactive

1.3714. Ko te wera ngingiha he 254.4 kJ/mol, ko te pāmahana tino nui ko te 306.8 ℃, ko te pehanga nui he 8.63 MPa. Ira hiko 68.9 ℃ (kapua tuwhera). Kiato 1.22, kiato kohu whanaunga 1.59 (hau =1), pehanga kohu kukū (24℃) 5.33kPa.

Ko te nui o te waikawa formic ka tio i te takurua.

Pūhui rāhuitia: hāora kaha, alkali kaha, paura whakarewa kaha.

Ko nga ahuatanga kino: ko te kohu me te hau ka hanga he ranunga pahū, ka puta te ngingiha me te pahū ki te ahi tuwhera me te kaha wera nui. Ka tauhohe ki nga waiora kaha.

Te whakarewatanga: he miscible ki te wai, he kore e rewa ki te waiwaro, he misible ki te waipiro.

I roto i te hauwai me te hau, ka puta te waikawa puka hei dimer e herea ana e nga here hauwai. I roto i te ahua haurehu, ka hua te hononga hauwai i te ine nui i waenga i te hau waikawa formic me te wharite hau pai o te ahua. Ko te wē me te waikawa pūkawa totoka kei roto i ngā rāpoi ngota waikawa pūmau tonu e herea ana e ngā here hauwai.

Ka tihorea te waikawa Formic ki te CO me te H2O i raro i te catalysis o te waikawa pungatara puri:

Na te hanganga motuhake o te waikawa formic, ka hono tika tetahi o ona ngota hauwai ki te roopu carboxyl. Ka taea ranei e koe te tiro hei hydroxyformaldehyde. No reira ko te waikawa formic he waikawa me te aldehyde.

He rite tonu nga ahuatanga o te waikawa puka ki te nuinga atu o nga waikawa warowairaka, ahakoa i raro i nga ahuatanga noa karekau te waikawa formic e hanga hei acyl chloride, anhydride ranei. Ko te matewai ka tihorea te waikawa puka ki te waro haukura me te wai. He rite nga ahuatanga whakaheke o te waikawa Formic ki te aldehydes. Ka taea e ia te timata i te tauhohenga whakaata hiriwa, ka whakaheke i nga katote hiriwa i roto i nga katote matatini ammonia hiriwa ki te whakarewa hiriwa, a ka waikuratia ano ki te warowaiha me te wai:

Ko te waikawa Formic anake te waikawa carboxylic ka taea te taapiri atu ki nga olefins. Ko te waikawa Formic i roto i te mahi o te waikawa (pērā i te waikawa pungatara, waikawa pūhāwai), me te olefins tere te tauhohenga ki te hanga hōputu. Heoi ano, ka puta ano he tauhohenga taha e rite ana ki te tauhohenga Koch, me te hua he waikawa carboxylic teitei ake.

Uara takirua o te octanol/wai whakarea wehewehe: -0.54, runga tepe pahūtanga % (V/V) : 57.0, raro tepe pahū % (V/V): 18.0.

Ko te waikawa Formic he kaihoko whakaheke kaha, ka puta pea te tauhohenga whakaata hiriwa. Ko te tino waikawa i roto i nga waikawa ngako kukū, a ko te 2.1x10-4 te tauwehenga. Ka pakaru ata ki te waro haukura me te wai i te pāmahana rūma. Ka whakamahana ki te 60 ~ 80 ℃ me te waikawa pungatara kaha ki te pirau me te tuku waro monoxide. Ka whakawerahia te waikawa formic ki runga ake i te 160 ° C, ka pirau ki te tuku i te hauhā me te hauwai. Ko nga tote whakarewa alkali o te waikawa formic ka whakamahana ki te 400 ° C hei hanga oxalates.
