The group X1 may be defined as a univalent hydrocarbyl radical of up to 30 atoms containing at least one nitrogen atom having a pKb in dilute aqueous solution at 18° C. of between 4 and 14 wherein the said at least one nitrogen atom is separated from the Q2 atom by between 1 and 3 carbon atoms. The group X2 is defined as X1, X3 or X4 or represents a univalent radical of up to 30 atoms having at least one primary, secondary or aromatic ring carbon atom wherein each said univalent radical is joined via said at least one primary, secondary or aromatic ring carbon atom(s) respectively to the respective atom Q2. Q1 and Q2 each independently represent phosphorus, arsenic or antimony.Type: ApplicationFiled: December 29, 2010Publication date: December 27, 2012Applicant: LUCITE INTERNATIONAL UK LIMITEDInventors: Graham Ronald Eastham, Mark Waugh, Paul Pringle, Thomas Philip William Turner

Publication number: 20120309613Abstract: A method of increasing the TON of a catalyst system for the monocarbonylation of ethylenically unsaturated compounds using carbon monoxide in the presence of a co-reactant, other than water or a source thereof, having a mobile hydrogen atom is described. The catalyst system is obtainable by combining: (a) a metal of Group (8, 9) or (10) or a suitable compound thereof; (b) a ligand of general formula (I) wherein the groups X3 and X4 independently represent univalent radicals of up to 30 atoms or X3 and X4 together form a bivalent radical of up to 40 atoms and X5 has up to 400 atoms; Q1 represents phosphorus, arsenic or antimony; and c) optionally, a source of anions. The method includes the step of adding water or a source thereof to the catalyst system. The method is preferably carried out in the presence of an electropositive metal.Type: ApplicationFiled: December 15, 2009Publication date: December 6, 2012Applicant: LUCITE INTERNATIONAL UK LIMITEDInventors: Graham Ronald Eastham, Philip Ian Richards
