FOERFARANDE FOER FRAMSTAELLNING AV BOLLFORMIGA MAGNESIUMALKOXIDPARTIKLAR. |
摘要 |
Finely divided, spherical magnesium alkoxide is provided by spray-drying of an alcoholic solution of the corresponding carboxylated magnesium alkoxide, followed by drying and decarboxylation, in which a) the solution is atomised through a two-component nozzle operating with interior atomisation and at 10 to 30 % of its capacity in the under-load range, b) into an inert accompanying gas which is under a pressure of 1.0 to 1.2 bar and has been preheated to 100 to 140 DEG C and is circulated co-currently, c) after which the finely divided carboxylated magnesium alkoxide formed is dried and decarboxylated. The magnesium alkoxide is used for the preparation of a catalyst for the polymerisation of alpha -olefins. |
