Patent number: 5003104Abstract: This invention involves a process for the carbonylation of a carbonylatable reactant, e.g., an alkyl ester, a dialkyl ether or mixtures thereof by reacting the same with carbon monoxide. The process comprises effecting the carbonylation in the presence of a solution of a catalyst system containing a rhodium compound, an iodide and a lithium component at a temperature of from 50.degree. C. to 400.degree. C. at a carbon monoxide partial pressure of 1 psig to 15,000 psig. Hydrogen may also be present. The invention also concerns a carbonylation catalyst system effective for the addition of carbon monoxide to a carbonylatable reactant which comprises a solution containing as essential components a rhodium containing active component, an iodide and a lithium component.Type: GrantFiled: October 31, 1988Date of Patent: March 26, 1991Assignee: BP Chemicals LimitedInventors: Frank E. Paulik, Arnold Hershman, Walter R. Knox, Robert G. Schultz, James F. Roth

Patent number: 4086195Abstract: Bitumen filled polyester foams are provided through a process which comprises forming a solution of a bitumen having a softening point of at least about 80.degree. C. and a cyclic diacid anhydride at a temperature above the softening point of a bitumen, the bitumen solution is then mixed with a monoterminal epoxide and a polyterminal epoxide in the presence of a blowing agent resulting in the initiation of an exothermic reaction. The process for producing bitumen filled polyester foams through the in situ polymerization of polyesters in a solution of bitumen and the foams produced by the process constitute the invention.Type: GrantFiled: March 2, 1977Date of Patent: April 25, 1978Assignee: Monsanto CompanyInventors: Walter R.
