Translation - urea characteristic The urea is one kind of achromatic color, tasteless, the odourlessness acicular or the orthogonal prism build crystallizes, in the actual production is granulated for the white or the tint; The granularity may be possible to be small greatly according to enterprise's characteristic; When heats up to 132.7℃ starts to melt, the solid urea density is 1.335g/cm 3, dissolves in the water and the few organic reagents, the urea assumes the alkalescency, may live the salifying with the acid function, when the temperature surpasses 60℃, the urea in the acid, the alkalinity or the neutral solution has the hydrolisis.

问题补充：尿素是一种无色、无味、无臭的针形或正交棱柱体形结晶，实际生产中为白色或浅色颗粒状；粒度则根据企业的特点可大可小；当加热到132.7℃开始熔化，固体尿素密度为1.335g/cm 3，溶于水和少量的有机试剂，尿素呈微碱性，可与酸作用生成盐，当温度超过60℃时，尿素在酸、碱性或中性溶液中发生水解。
