Patent number: 7597726Abstract: New, highly effective Mannich detergents for use in hydrocarbon fuels are described which reduce engine deposits in spark and compression ignition internal combustion engines. They are Mannich condensation reaction products obtained from reacting: (i) a polyamine having a sterically-hindered primary amino group, (ii) a hydrocarbyl-substituted hydroxyaromatic compound, and (iii) an aldehyde. These Mannich detergent compounds may be dispersed in a liquid carrier to provide a fuel additive concentrate for hydrocarbon engine fuels which effectively control engine deposit formation in intake valves and also other engine regions such as port fuel injectors and combustion chambers.Type: GrantFiled: January 20, 2006Date of Patent: October 6, 2009Assignee: Afton Chemical CorporationInventors: Peter W. Hou, Dennis J. Malfer, May Duffield Thomas, William J. Colucci

Patent number: 7572877Abstract: An object of the present invention is to provide a modified cyclic aliphatic polyamine having a low viscosity and a small content of unreacted polyamine which can provide, when it is used as a curing agent for epoxy resin, an epoxy resin composition having an improved workability without adding solvent or diluent and an excellent property of epoxy resin cure product. The above modified cyclic aliphatic polyamine is obtained by addition reaction of a cyclic aliphatic polyamine such as isophoronediamine and norbornanediamine and an alkenyl compound such as styrene. The modified cyclic aliphatic polyamine thus obtained is added in epoxy resin to be used as a curing agent for epoxy resin.Type: GrantFiled: October 22, 2007Date of Patent: August 11, 2009Assignee: Mitsubishi Gaschemical Company, Inc.Inventors: Takeshi Koyama, Tetsushi Ichikawa, Hisayuki Kuwahara, Masatoshi Echigo
