The AMO can be obtained by polymerizing polyoxyalkylene amine having molecular weight over 1000, p-cresol and formaldehyde. The present invention further discloses a nanosilica plate, which can be obtained by extracting the above complex with a hydroxide or a chloride of alkali metal or alkaline-earth metal, and consequently, the AMO intercalating agent can be recycled for reusing.

Abstract: The present invention discloses an exfoliative clay and a derivative thereof and a method for producing the same. The exfoliative clay is formed by emulsion exfoliating an inorganic layered silicate clay with an amphibious intercalating agent by powerfully stirring at 60-180° C. and not less than 14.7 psig. The amphibious intercalating agent is obtained by copolymerizing polyoxyalkylene amine having molecular weight over 1,800 and polypropylene-grafting-maleic anhydride (PP-g-MA). Before emulsion exfoliation, the intercalating agent is acidified with an inorganic acid. The acidification is the key step for obtaining nanoscale of emulsifying particles less than 100 nm for the exfoliation. The exfoliative clay can be further extracted with a hydroxide or a chloride of alkali metal or alkaline-earth metal to obtain a derivative in the form of nanosilica plates which is free of organic portions.

Abstract: An improved process to prepare poly(oxyalkylene)amide for gasoline additives involves three consecutive reactions. The reactions are (1) amidation of water-soluble low molecular weight of polyalkylene polyamine with alkyl acetate at an elevated temperature under N2 pressure to convert amines to amides, (2) Butoxylation of the amides with 1,2-epoxybutane to prepare the poly(oxyalkylene) amides, and (3) selective hydrolysis of in situ poly(oxyalkylene)-amine-ester-amides into poly(oxyalkylene)-amine-alcohol-amides and removal of acetic acid byproducts, via acid/base hydrolysis and water extraction procedures. The process step of selective hydrolysis is essential for removal the harmful composition of poly(oxyalkylene)-amine-ester-amides in resulting the better performance of the additive, particularly the positive engine's octane requirement or reducing the combustion chamber deposits.

Abstract: The present invention is one kind of gasoline additives. The compounds consist of tertiary amine, amide and poly(oxybutylene) backbone in the same molecule. The process of making this type of products required an initiator containing primary amine and tertiary amine as the starting diamines. The primary amine will be converted into amide, while the tertiary amine remained intact. Then the amide is converted into butoxylates through butoxylation at CON—H position. The preparation therefore involved two steps: (1) amidation of diamines containing primary/tertiary amines with ethyl acetate to form amidoamines, and (2) butoxylation of this amidoamines to poly(oxybutylene)amidoamine. The product is gasoline soluble and can be used as additive having good performance of detergency and octane requirement reduction.
