560206000 | Preparing esters by carbonylation | 6 |
20080281122 | Preparation of palladium-gold catalysts - A method for preparing supported palladium-gold catalysts is disclosed. The method comprises increasing the porosity of a titanium dioxide support, impregnating the support with a palladium salt, a gold salt, and an optional alkali metal or ammonium compound, and reducing the calcined support. The resultant supported palladium-gold catalysts have increased activity in the acetoxylation. | 11-13-2008 |
20120101298 | CARBONYLATION PROCESS - A process for the production of acetic acid and/or methyl acetate by carbonylating methanol and/or reactive derivatives thereof with carbon monoxide in the presence of a catalyst which is a mordenite which has been treated with an aqueous basic solution containing at least one of aluminate ions and gallate ions and has a silica:X | 04-26-2012 |
20150126766 | PROCESS FOR PREPARING 4-HYDROXYBUTYL ACRYLATE - A process for preparing 4-hydroxybutyl acrylate by transesterifying an alkyl acrylate with 1,4-butanediol in the presence of a dialkyltin oxide such that each of the alkyl groups has 4 to 8 carbon atoms, characterized in that the amount of the dialkyltin oxide is adjusted to 0.00001 to 0.01 moles per one mole of the alkyl acrylate. | 05-07-2015 |
