| titleOfInvention | Process for the preparation of polyvinyl alcohol |
| abstract | A process for the preparation of polyvinyl alcohol by catalytic reaction of an alcoholic polyvinyl ester solution containing 20 to 80 wt .-% polyvinyl ester in heavy mixing equipment at a temperature of 10 ° C to 50 ° C, characterized in that the alcoholic polyvinyl ester solution and the catalyst before be premixed into the heavy mixing unit in an upstream mixing unit discontinuously or continuously, wherein in discontinuous premix, the polyvinyl ester solution is introduced in the upstream mixing unit and with an aqueous, diluted with alcohol or with an alcoholic solution of the catalyst, strongly and intimately mixed until a homogeneous mixture is present, wherein the molar ratio of polyvinyl ester to alkaline Catalyst between 2000/1 and 10/1, and the premixed reaction solution is then transferred to the heavy mixing unit, or with continuous premixing of the polyvinyl ester solution in the upstream mixing unit, during the filling of the heavy mixing unit continuously the catalyst solution outside the heavy mixing unit is mixed in an upstream mixing unit, ... |
