Patent number: 11613510Abstract: A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of methylcyclohexane as a reaction solvent and a catalyst system comprising a rhodium complex and a substituted or unsubstituted diphosphine ligand. The use of the methylcyclohexane increases the reaction rate while also giving a high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde and improving the separation of the hydroxyaldehyde products from the catalyst system.Type: GrantFiled: April 7, 2022Date of Patent: March 28, 2023Assignee: Lyondell Chemical Technology, L.P.Inventors: Daniel F. White, Beaven S. Mandimutsira, Robert J. Rebman

Patent number: 6536173Abstract: The invention is a covering for a suspended ceiling grid system. The covering is particularly suited to be retrofitable onto an installed suspended ceiling grid system. The covering is preferably a plastic cup that can be snap fit onto the main runners or cross-tees of the installed suspended ceiling grid system, and the covering includes an elongate body having an opposed flange and lip which facilitate easy assembly and disassembly from a suspended ceiling grid system. The elongate body of the covering may be planar or non-planar. The covering may also have notches defined in the flange and lip in a suitable arrangement.Type: GrantFiled: April 16, 2001Date of Patent: March 25, 2003Assignee: Acoustic Ceiling Products, L.L.C.Inventor: Robert J. Rebman
