Latest Patents

One of Stanley Leonard's latest patents is titled "Process for producing a cyclic acetal in a heterogeneous reaction system." This patent discloses a method where a formaldehyde source is combined with an aprotic compound and contacted with a heterogeneous catalyst. This process facilitates the conversion of the formaldehyde source into a cyclic acetal, such as trioxane. The catalyst may include a solid catalyst, such as an ion exchange resin. In one embodiment, the process is utilized for converting anhydrous formaldehyde gas to trioxane, which can be produced from an aqueous formaldehyde solution through extractive distillation. The aprotic compound and formaldehyde solution can be extracted from the reaction product and recycled into the process.

Another significant patent is the "Method of polyarylene sulfide crystallization." This method describes the formation of a semi-crystalline polyarylene sulfide through the reaction of a sulfur-containing monomer with a dihaloaromatic monomer in an organic amide solvent. The resulting polymer is then combined with a pre-heated crystallization solution, and the mixture is slowly cooled to crystallize the polymer.
