METHOD FOR OBTAINING BISPHENOL-A FROM POLYCARBONATE WASTE USING MICROWAVE RADIATION

摘要

The invention consists of a method for obtaining bisphenol-A from the decomposition of polycarbonate waste produced with bisphenol-A, which makes use of microwave technology in order to heat the reaction. The method consists in preparing an alkaline solution in an alcoholic medium comprising metal hydroxide in an alcohol, in which the hydroxide can be sodium or potassium hydroxide and the alcohol is methanol, and in which the solution is mixed with the polycarbonate waste containing bisphenol-A and placed in a reactor, reacting and agitating same in a device provided with a microwave radiation generator for chemical reactions, maintaining the temperature between 90 and 150°C, for between 3 and 10 minutes, preferably between 5 and 7 minutes, in order to break down the polycarbonate and obtain the bisphenol-A.
