um método para a redução da mutagenicidade de compostos aromáticos policíclicos (pac's) tendo uma ou mais regiões de baía, que envolve a alquilação dos pac's com um agente de alquilação na presença de um catalisador para baixar a mutagenicidade para tão baixo quanto cerca de 0,1. os resultantes compostos aromáticos policíclicos alquilados retêm suas propriedades físicas e químicas para o uso industrial seguro incluindo como óleos de processamento de borracha, tintas, etc. A method for reducing the mutagenicity of polycyclic aromatic compounds (PAC's) having one or more bay regions which involves alkylating the PAC's with an alkylating agent in the presence of a catalyst to lower the mutagenicity down to as much as about 0.1. The resulting alkylated polycyclic aromatic compounds retain their physical and chemical properties for safe industrial use including as rubber processing oils, inks, etc.
