【摘要】 含脲反应物在有惰性载体液态烃的情况下（惰性载体液态烃之沸点在指定反应温度内）在１００－１５０℃控制温度的条件下进行热解，由此可得到一个高产率的缩二脲自动缩合产物而未反应的尿素含量却相对很低。更多还原

【Abstract】 A urea - containing reactant is pyrolyzed under controlled temperature conditions of from 100 to 150℃ in the presence of an inert hydrocarbon carrier liquid having a boding point at about the predetermined reaction temperature thereby providing an autocondensation product mass rich in biuret and having a relatively low residual content of unconverted urea.更多还原
