Eg. Smirnova et al., STABILITY OF OPERATION OF A HETEROGENEOUS CATALYST UNDER CONDITIONS OF BATCH POLYMERIZATION OF TETRAHYDROFURAN, Russian journal of applied chemistry, 70(4), 1997, pp. 597-600
Comparative studies of the operation stability of various catalysts we
re performed. The behavior of catalysts was studied in the course of t
etrahydrofuran polymerization during 6 months. The process was perform
ed in a batch reactor (with operation cycle of 7 days).
