PREPARATION OF PR-1 COMPOUND BASED ON LOCAL RAW MATERIALS AND STUDY OF ITS PHYSICOCHEMICAL PROPERTIES

Аннотация

The optimal ratio of components in the preparation of PR-1 is 1:1:1, and the optimal temperature for 40 minutes is 80 0C. Under these conditions, the productivity of the installations is up to 95%. The ratio of starting products is 2:1:1 and 1:2:1, the highest dry residue is produced, but the washability of the resulting products is low. The duration of the reaction is also important in the production of chemical products. KEYWORDS Hydrolyzed polyacrylonitrile, sulfate acid, ethanol, sodium hydroxide, PR-1, Infrared spectroscopy.
