Title: Innovations of Yung-Sheng Ho in Gasoline Additives
Introduction
Yung-Sheng Ho is a notable inventor based in Chiai, Taiwan, recognized for his contributions to the field of gasoline additives. He holds three patents that focus on improving the performance and efficiency of fuel additives, particularly through innovative chemical processes.
Latest Patents
One of his latest patents is titled "Process for manufacturing gasoline additives of ester-free polyoxyalkylene amide." This invention outlines an improved method for preparing poly(oxyalkylene)amide for gasoline additives through three consecutive reactions. The first step involves the amidation of water-soluble low molecular weight polyalkylene polyamine with alkyl acetate at elevated temperatures under nitrogen pressure. This converts amines to amides. The second step is the butoxylation of the amides with 1,2-epoxybutane to create poly(oxyalkylene) amides. The final step is the selective hydrolysis of in situ poly(oxyalkylene)-amine-ester-amides into poly(oxyalkylene)-amine-alcohol-amides, which also includes the removal of acetic acid byproducts. This selective hydrolysis is crucial for eliminating harmful components, thereby enhancing the additive's performance, particularly in improving engine octane requirements and reducing combustion chamber deposits.
Another significant patent is for "Poly(oxyalkylene) amide-amine gasoline additives." This invention describes a type of gasoline additive composed of tertiary amine, amide, and a poly(oxybutylene) backbone within the same molecule. The preparation process requires an initiator containing both primary and tertiary amines as starting diamines. The primary amine is converted into amide, while the tertiary amine remains unchanged. The amide is then transformed into butoxylates through butoxylation at the CON—H position. This process involves two main steps: amidation of diamines with ethyl acetate to form amidoamines, followed by butoxylation to produce poly(oxybutylene) amidoamine. The resulting product is gasoline soluble and exhibits excellent performance in terms of detergency and octane requirement reduction.
