Abstract:
The present invention provides an acid catalyst complex comprising an organosulfonic acid having at least one covalent carbon-fluorine bond or one covalent carbon-phosphorus bond provided by a phosphono radical which has been contacted with a Lewis Acid to produce a catalyst complex containing said Lewis Acid. The present invention also provides a process for the conversion of a reactant into a reaction product in the presence of said catalyst complex. In particular, the catalyst complex is useful for providing a high octane alkylate stream by converting a mixture comprising isoparaffins and olefins into said alkylate in the presence of said catalyst complex.
Abstract:
A method of fluorometrically detecting the concentration of chemical components in oxidizing formulations is disclosed. In a particular embodiment the detection is of the stabilizing component of picolinic acid, present in such formulations, although any component which fluoresces may be detected. According to the invention sample preparation of the oxidizing formulation includes adding to said sample an excess of reducing agent to bind peracid, and in the case of picolinic acid, adding to said sample an excess of terbium chloride. The sample then is subjected to radiation to induce fluorescence and the concentration of said chemical component is determined by a linear relationship between fluorescence emitted and the concentration of the target chemical.
Abstract:
Self-indicating chemistries are provided for visual detection by a user of efficacious levels of peroxycarboxylic acid concentrations in a solution produced in situ .

Abstract:
The present invention provides an acidic antibiotic composition comprising acetic acid, hydrogen peroxide, peracetic acid, and acetylsalicylic acid. The antibiotic composition may comprise acetylsalicylic acid in an amount from 0.1 % 10 % based on weight. The present invention further provides a preparation method comprising mixing a first solution comprising acetic acid, hydrogen peroxide and peracetic acid with a second solution comprising acetylsalicylic acid. In the diluted solution of the antibiotic composition, acetylsalicylic acid is consistently hydrated to provide acetic acid, and the hydrate salicylic acid acts as another antibiotic agent. Consequently, the antibiotic composition forms an equilibrated composition and can be used for a long period of at least 3 weeks even after being diluted with purified water.
Abstract:
