99.5% CAS 75-12-7 Formamide

Fa'amatalaga Puupuu:

99.5% CAS 75-12-7 Formamide
faʻaaogaina mo mea mataʻutia o vailaʻau faʻasolosolo, mea manogi, vali ma isi, faʻapea foʻi ma se solvent mo le viliina o alava faʻapipiʻi, gaosiga palasitika, le gaosiga o le vaitusi laupapa. Fa'aaogaina fo'i e fai ma sui o le fa'againa o pepa, fa'ameamea o le suau'u suau'u ma fale faufale, carburizing nitriding agent i fale faufale, fa'amalulu kelu manu ma polar solvent of organic synthesis.

Meatotino: vai e leai se lanu ma manino, sina amonia. Liu liusuavai 2.55 ℃, Mea fa'apuna 210-212 ℃ (vaega fa'apala i le 180 ℃), Fa'asao moli154 ℃, Kalave fa'apitoa 1.1334 (20 ℃). Hygroscopic, fa'afefiloi i le vai ma le ethanol, e mafai ona solu i le benzene, chloroform ma le eter.

Fa'aoga: mea mata o vaila'au fa'afoma'i, mea manogi, vali ma isi, fa'apea fo'i ma se solvent mo le viliina o alava synthetic, gaosiga palasitika, le gaosiga o le vaitusi casein laupapa. Fa'aaogaina fo'i e fai ma sui o le fa'againa o pepa, fa'ameamea o le suau'u suau'u ma fale faufale, carburizing nitriding agent i fale faufale, fa'amalulu kelu manu ma polar solvent of organic synthesis.

afifiina, teuina ma felauaiga: 220L palasitika pa'u po'o le sila-palasitika paelo tu'ufa'atasi. E tatau ona tapuni le tapuni ina ia puipuia ai le tafe ma aloese mai le pipii i le vai. Teu i se nofoaga malulu, matutu, mamao ese mai le afi ma le vevela.
