专利号:US-10487048-B2 优先权日:2015-03-13 标 题:Configuration and its use in process for synthesis of alkyl carbamates from alkyl alcohol and urea in a tubular reactor 发明人:RANADE VIVEK VINAYAK; KELKAR ASHUTOSH ANANT; RANE VILAS HARI; KINAGE ANIL KISAN; MOTE DHANANJAY RAVINDRA; SHINGOTE SAVITA KIRAN; ROY LALITA SANJIB 权利人:COUNCIL SCIENT IND RES 摘要:The present invention discloses an improved catalyst free process for synthesis of alkyl carbamates in an integrated system comprising a tubular reactor and a striper. The process comprises reacting urea and an alcohol in said tubular reactor under autogeneous pressure; wherein said process provides >90% selectivity towards alkyl carbamate. The mixture of urea and alcohol is N fed to the tubular reactor at a particular feed rate. The tubular reactor is heated externally under autogeneous pressure to carry out a synthesis reaction producing alkyl carbamate and ammonia. The ammonia is removed from the tubular reactor by the striper. The tubular reactor and the stripper are arranged in series to reduce the equilibrium limitations of the reaction and drive the reaction in forward direction.
