Zoo siv
N, n'-diphenylurea, tseem hu ua DPU, yog ib hom tshuaj pleev xim rau cov tshuaj c13h12n2o. Nws yog cov khoom dawb, crystalline uas yog sparingly soluble hauv dej tab sis soluble hauv ethanol thiab acetone. N, n'-diphenylurea muaj ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb.000 ntawm lub ntsiab siv roj hmab hauv lub ntsuas hluav taws xob hauv cov txheej txheem volcanization. Nws ua raws li tus neeg sib koom ua ke nrog cov txiv lws suav nrog cov txiv lws suav nrog rau kev kho kom nrawm nrawm, tshwj xeeb yog cov log tsheb ntau lawm. N, n'-diphenylenea yuav pab txhim kho lub zog tensile, hardness, thiab lwm yam tshuaj ntawm cov tshuaj tua roj hmab kuj tseem pom cov kev siv tshuaj lom neeg hauv ntau yam organic syntheses. Nws tuaj yeem siv rau hauv kev npaj ntawm carbamates, Isocyanates, thiab urethanes, thiab agnemicals. N, n'-diphenylurea tseem muaj kev cuam tshuam nrog synthesis ntawm antioxidants yuav muaj kev phom sij rau kev noj qab haus huv, thiab kev ceev faj txog kev nyab xeeb thaum tuav cov compound no. Nws raug nquahu kom siv cov khoom tiv thaiv tus kheej, xws li hnab looj tes thiab goggles, thiab ua haujlwm hauv qhov chaw muaj cua zoo. Kev saib xyuas yuav tsum tau noj kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij thiab nqus tau cov khoom siv. Kev siv tshwj xeeb, kev ceev faj, thiab cov cai yuav sib txawv raws li cov ntsiab lus teb thiab cov ntawv thov.
