Patent number: 8829243Abstract: A method for removing methylene-bridged polyphenyl polyamines from an aqueous stream comprising said methylene-bridged polyphenyl polyamines according to the invention comprises the steps of Providing a pertraction equipment comprising a membrane with a first side and a second side opposite to said first side; Bringing an aqueous stream comprising methylene-bridged polyphenyl polyamines into contact with the first side of the membrane and bringing an organic stream into contact with the second side of the membrane, thereby causing the methylene-bridged polyphenyl polyamines to transfer from the aqueous stream through the membrane to the organic stream. The method further comprises, before bringing the aqueous stream and organic stream in contact with the membrane, the step of wetting the membrane with a liquid having a surface tension of less than 40 mN/m.Type: GrantFiled: July 22, 2010Date of Patent: September 9, 2014Assignee: Huntsman International LLCInventors: Rabah Mouazer, Johannes Lodewijk Koole, Ramon Scheffer

Patent number: 8802890Abstract: The present invention relates to a process for manufacturing isocyanates from an amine compound. The process comprises the steps of a) Providing chlorine; b) Providing carbon monoxide; c) Reacting said chlorine and said carbon monoxide for providing phosgene, the carbon monoxide being provided in an adjustable molar excess; d) Providing an amine compound and phosgenating said amine compound using said phosgene thereby providing said isocyanate; the process further comprises adjusting said adjustable molar excess, i.e. the molar excess of carbon monoxide, for adjusting the color of the isocyanate.Type: GrantFiled: November 5, 2009Date of Patent: August 12, 2014Assignee: Huntsman International LLCInventors: Robert Henry Carr, Johannes Lodewijk Koole, Udo Brian Dave Mike Rodger Bruinsma
