Khoom Description
Kev taw qhia thiab kev siv CAS:2724-69-8|1-Methyl-3-phenyl-2-thiourea
Cov khoom siv tshuaj: Cov khoom no yog flake crystal, mp113 degree, soluble hauv ethanol thiab ether, thiab soluble hauv dej. Kev Siv: 1-Methyl-3-phenylthiourea tuaj yeem siv los npaj 2-methylaminobenzothiazole, qhov nruab nrab ntawm cov tshuaj tua kab mob methylbenthiuron. Kev tsim cov txheej txheem kev npaj yog ntxiv sodium carbonate tov rau lub reactor, ntxiv cov pa roj carbon disulfide tov ntawm aniline rau lub reactor, tswj cov tshuaj tiv thaiv kub ntawm 40 mus rau 50 degree los tsim sodium anilinodithiocarbamate (PhNHCS2Na), thiab ces ntxiv formazan. Cov tshuaj amine yog nplawm tas li kom tau cov khoom siv lead ua, uas tau lim thiab ntxuav kom tau txais cov khoom tiav.
