Patent number: 5103042Abstract: Polyethers having terminal allyl unsaturation are subject to hydrogenolysis by reaction with a hydrogen donor in the presence of a n-allyl complex forming catalyst. The product polyethers have extremely low levels of unsaturation, and thus are useful in preparing polyurethanes having improved properties and processing.Type: GrantFiled: May 23, 1990Date of Patent: April 7, 1992Assignee: The Dow Chemical CompanyInventors: Visweswara R. Durvasula, Franz J. Luxem

Patent number: 5041621Abstract: Process is disclosed for the preparation of dihydroxy esters such as hydroxypivalyl hydroxypivalate from hydroxy aldehydes such as hydroxypivaldehyde by contacting said hydroxy aldehydes with low levels of at least one elemental metal selected from a defined group of metals. Reaction product is readily recovered without the need for extensive catalysts neutralization and/or removal procedures.Type: GrantFiled: September 27, 1989Date of Patent: August 20, 1991Assignee: Eastman Kodak CompanyInventors: Don L. Morris, Gary C. Luce
