99.5% CAS 75-12-7 Formamide
Formamide 99.5% CAS 75-12-7
-Molecular structure
Molecular formula: HCONH2
Molecular uremu: 45.041
Properties: isina ruvara uye yakajeka mvura, zvishoma ammonia. Melting point 2.55 ℃, Boiling point 210-212 ℃ (yakaora zvishoma pa180 ℃), Flash point154 ℃, Specific gravity 1.1334 (20 ℃). Hygroscopic, yakasanganiswa nemvura uye ethanol, inonyungudika zvishoma mubenzene, chloroform uye ether.
Zvishandiso: mbishi zvinhu zveSynthetic mushonga, zvinonhuhwirira, dhayi uye nezvimwe, zvakare sechinhu chinonyungudutsa chekugadzira fibers, kugadzirwa kwepurasitiki, kugadzirwa kwehuni inki. Inoshandiswawo semugadziri wekugadzira mapepa, coagulant yekuchera mafuta uye indasitiri yekuvaka, carburizing nitriding agent muindasitiri yekugadzira, mhuka glue softener uye polar solvent yeorganic synthesis.
Packaging, kuchengetedza uye kutakura: 220L plastiki dhiramu kana simbi-plastiki inoumba mbiya. Chivharo chinofanira kuvharwa kudzivirira kubuda uye kudzivirira kusangana nemvura. Kuchengetwa munzvimbo inotonhorera, yakaoma, kure nemoto uye kupisa.
Zvinodiwa: Q / 320412 XY204-2008
