Title: Innovations of Stephen A Haut
Introduction
Stephen A Haut is an accomplished inventor based in Chesterfield, VA (US). He has made significant contributions to the field of smoking compositions and chemical synthesis, holding a total of 2 patents. His work has been instrumental in enhancing flavor profiles and improving synthesis processes in various applications.
Latest Patents
One of Haut's latest patents is titled "Smoking compositions containing a glycosylamine flavorant additive." This invention provides smoking compositions that incorporate a glycosylamine compound as a flavorant-release additive. Under cigarette smoking conditions, an additive such as 1-amino-1-deoxyglucose pyrolyzes into volatile constituents, which enhance the flavor of the mainstream smoke and the aroma of sidestream smoke.
Another notable patent is the "Process for synthesis of carboxamides." This invention outlines an improved process for synthesizing carboxamides by reacting 3-p-menthyl halide with magnesium to form 3-p-menthylmagnesium halide Grignard reagent. The Grignard reagent is then reacted with hydrocarbyl isocyanate at a temperature below about -20 degrees Celsius to produce N-hydrocarbyl-p-menthane-3-carboxamide. The resulting product comprises a mixture of geometric isomers with a weight ratio of 3-p-menthyl to 3-p-neomenthyl that can reach as high as 9:1 under optimal conditions.
