99.5% CAS 75-12-7 Formamide
Formamide99.5% CAS 75-12-7
-Ubume bemolekyuli
Ifomula yemolekyuli: HCONH2
Ubunzima bemolekyuli: 45.041
Iipropati: ulwelo olungenambala kunye nolubonakalayo, i-ammonia encinci. Indawo yokunyibilika 2.55 ℃, Indawo yokubilisa 210-212 ℃ (ibolile ngokuyinxenye ngo-180 ℃), indawo yokudanyaza154 ℃, Umxhuzulane okhethekileyo 1.1334 (20 ℃). IHygroscopic, ixubene namanzi kunye ne-ethanol, inyibilika kancinane kwi-benzene, i-chloroform kunye ne-ether.
Ukusetyenziswa: izinto ekrwada amayeza Synthetic, iziqholo, idayi kunye nabanye, kwakhona njengesinyibilikisi ukusonta imicu zokwenziwa, processing zeplastiki, imveliso yeinki casein ngamaplanga. Ikwasetyenziswa njengearhente yokulungisa amaphepha, icoagulant yokomba ioyile kunye neshishini lokwakha, i-carburizing nitriding agent kwishishini le-Foundry, isithambisa seglu yezilwanyana kunye ne-polar solvent ye-organic synthesis.
Ukupakishwa, ukugcinwa kunye nokuthutha: i-220L idrum yeplastiki okanye i-steel-plastic composite barrel. Isivalo kufuneka sivalwe ukuthintela ukuvuza kwaye uphephe ukudibana namanzi. Igcinwe kwindawo epholileyo, eyomileyo, kude nomlilo kunye nobushushu.
