I-99.5% CAS 75-12-7 IMformamide
Formamide 99.5% CAS 75-12-7
-Isakhiwo samangqamuzana
Ifomula yamangqamuzana: HCONH2
Isisindo molecular: 45.041
Izakhiwo: Uketshezi olungenamibala nasobala, i-ammonia kancane. I-Melting Point 2.55 ℃, i-Boiling Photo 210-212 ℃ (ngokwengxenye ebolile ngo-180 ℃), i-Flash Point154 ℃, amandla athile adonsela phansi 1.1334 (20 ℃). I-Hygroscopic, engazinzi ngamanzi ne-ethanol, incibilika kancane e-benzene, chloroform ne-ether.
Isebenzisa: Izinto eziluhlaza zokwenziwa umuthi wokwenziwa, izinongo, udayi kanye nabanye, futhi njenge-solvent yokuxubha kwemicu yokwenziwa, ukucubungula ipulasitiki, ukukhiqizwa kwe-ink yepulasitiki. Ibuye isetshenziswe njenge-ejenti yokucubungula amaphepha, ubumbano lwemboni yokwakha uwoyela kanye nezokwakha, ukuvumelanisa i-ejenti ye-nitriding embonini ethosiwe, i-animar glue softvener ye-organic synthersis.
Ukuwowapha, Isitoreji nokuhamba: I-220L DRUM DRUM noma i-Steel-Plastice Composite Barrel. Isembozo kufanele ivalwe ukuvikela ukuvuza futhi igweme ukuxhumana namanzi. Igcinwe endaweni epholile, eyomile, kude nomlilo nokushisa.
Ukucaciswa: Q / 320412 xY204-2008
