1. A process to separate lignin from a lignocellulosic feedstock, said process comprising the steps of:
providing said lignocellulosic feedstock;
providing a vessel;
providing a composition comprising;
an acid;
a modifying agent selected from the group consisting of: sulfamic acid; imidazole; imidazole derivatives; taurine; a taurine derivative; a taurine-related compound; alkylsulfonic acid; arylsulfonic acid; triethanolamine; and
combinations thereof;
a peroxide salt; and
a peroxide;
