Latest Patents

Reynolds' latest patents include groundbreaking work on phthalocyanines. His first patent focuses on phthalocyanine compounds that are substituted by one to eight substituents of the formula (—O—R—O—), where R is a 1,2-arylene group. These compounds are preferably substituted by catechol, with additional substituents that may include hydrocarlyloxy, hydrocarbylthio, halogen, and sulfonic acid or a salt thereof. Another significant patent involves a process for treating stained fabrics with manganese phthalocyanines. This patent describes a substituted phthalocyanine in which at least one of the peripheral carbon atoms in the 1-16 positions of the phthalocyanine nucleus is linked via an oxygen atom or a sulfur atom to an organic radical. The remaining peripheral carbon atoms can be unsubstituted or substituted by various atoms or groups, including sulfonated derivatives. This innovation also includes compositions comprising these compounds and their use as cleaning materials.
