Methacrylamide
katundu wa mankhwala
Fomula ya mankhwala :C4H7NO Kulemera kwa maselo :85.1 CAS:79-39-0 EINECS:201-202-3 Malo osungunuka :108 ℃ Malo owira: 215 ℃
Chiyambi cha malonda ndi zinthu zake
Methacrylamide ndi mankhwala achilengedwe okhala ndi formula ya molekyulu C4H7NO. Amadziwikanso kuti 2-methylacrylamide (2-methyl-propenamide), 2-methyl-2-propenamide (2-propenAMID), α-propenamide (α-methylpropenamide), Alpha-methyl acrylic amide). Pa kutentha kwa chipinda, methylacrylamide ndi kristalo woyera, zinthu zamafakitale zimakhala zachikasu pang'ono. Zimasungunuka mosavuta m'madzi, zimasungunuka mu mowa, methylene chloride, zimasungunuka pang'ono mu ether, chloroform, sizisungunuka mu petroleum ether, carbon tetrachloride. Pa kutentha kwakukulu, methylacrylamide imatha kupanga polymer ndikutulutsa kutentha kwambiri, zomwe zimakhala zosavuta kuyambitsa kuphulika kwa mitsempha yamagazi ndi kuphulika. Pakakhala moto wotseguka, methylacrylamide yotentha kwambiri, kuwonongeka kwa kuyaka, kutulutsidwa kwa carbon monoxide woopsa, carbon dioxide, nitrogen oxide ndi mpweya wina wa nitrogen oxide. Chogulitsachi ndi mankhwala oopsa. Chimatha kukwiyitsa maso, khungu ndi nembanemba ya mucous. Chiyenera kutsekedwa ndikusungidwa kutali ndi kuwala. Methylacrylamide ndi gawo lapakati pakupanga methyl methacrylate.
gwiritsani ntchito
Amagwiritsidwa ntchito makamaka pokonzekera methyl methacrylate, organic synthesis, polymer synthesis ndi zina. Kuphatikiza apo, methylacrylamide kapena silika degumming, dyeing isanayambe kuonda.
phukusi ndi mayendedwe
B. Chogulitsachi chingagwiritsidwe ntchito, 25KG，BAGES.
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
