Abstract (en)
[origin: DE10102172A1] The invention relates to a method for the synthesis of cellulose carbamate and a transport device (1) for transporting a cellulose slurry (4) dissolved in an organic reaction carrier. Until now, series of stirred-tank reactors were used for the synthesis of cellulose carbamate. Said series of stirred-tank reactors are complex and cause irregularities in the quality of the cellulose carbamate due to a wide range of retention time of the cellulose slurry in the series of stirred-tank reactors. According to the invention, a transport device (1) is used as a reactor system to carry out the continuous synthesis of cellulose carbamate or to enable said synthesis to be carried out. To this end, a cellulose slurry (4) suspended in an inert organic reaction carrier is heated in the continuous transport device (1) by means of a heating device (25, 26, 27), and is maintained essentially at the reaction temperature when transported in the transport device (1) along a transport track (5).
