Title: The Innovations of Josef Helmut Weinmaier
Introduction
Josef Helmut Weinmaier is a notable inventor based in Mühldorf, Germany. He has made significant contributions to the field of chemistry, particularly in the development of innovative preparations and methods for producing acyl peroxides. With a total of three patents to his name, Weinmaier's work has implications for various industrial applications.
Latest Patents
One of his latest patents is titled "Preparation for initiating radical reactions." This preparation comprises a mixture of dibenzoyl peroxides, which contains 50 to 99.7 mole % of a symmetric dibenzoyl peroxide and 0.3 to 50 mole % of asymmetric dibenzoyl peroxides. This mixture shows a reduced decomposition temperature compared to the symmetric dibenzoyl peroxide and is suitable for hot cross-linking silicone rubber. The preparation can be produced by reacting a mixture containing a first benzoyl chloride and a second benzoyl chloride that is different from the first, with hydrogen peroxide. The mixture of benzoyl chlorides contains 70 to 99.7 mole % of the first benzoyl chloride and 0.3 to 30 mole % of the second benzoyl chloride.
Another significant patent is the "Continuous method for producing acyl peroxides." This invention relates to a continuous method where an acyl chloride, carboxylic acid anhydride, or chloroformate is reacted with an organic hydroperoxide or hydrogen peroxide in at least two mixed reaction zones connected in series. The method allows for reliable reactions with high space-time yields, enhancing the efficiency of acyl peroxide production.
