| abstract | Usage: inhibitors of radical processes, stabilizers of polymeric materials, derivatives of mesitylene. SUMMARY OF THE INVENTION: Preparation of 2,4,6-tris- (4-hydroxy-3 .5-di-tert-butylbenzyl) mesitylene by alkylation of mesitylene with 4-hydroxy-3,5-di-tert-butylbenzyl) acetate in chloride medium methylene. As the catalyst, polymeric perfluorosulfonic acid of the general formula - (CF2-CF2M-fV-CF OCR CF (CFj) CF2CF2S03hafl, where n: m is 100-200, grafted onto the polymer-fluoroethylene in an amount of 10-50 wt.%, With a mass ratio of mesitylene-stabilizer equal to 1: (1-1.7). yield 85-Ј |
