Patent number: 9440944Abstract: A process for making a cyclic compounds such as cyclic acetal or cyclic ketones by feeding aldehyde or ketone compounds and polyhydroxyl compounds to a reaction zone at a molar ratio of polyhydroxyl compounds to aldehyde or ketone compounds of at least 3:1, reacting these compounds in the presence of a solid acid such as an acidic ion exchange resin, to generate a liquid reaction mixture without separating water from the reaction mixture as it is being formed in the reaction mixture, withdrawing the liquid reaction mixture from the reaction zone as a liquid product stream, and feeding the liquid reaction product stream to a distillation column to separate cyclic acetal compounds from unreacted polyhydroxyl compounds, and optionally recycling back the unreacted polyhydroxyl compounds to the reaction zone. The process produces cyclic acetal compounds in yields of at least 90% with long catalyst life. The process is also suitable to make cyclic ketals from ketone compounds.Type: GrantFiled: July 22, 2014Date of Patent: September 13, 2016Assignee: Eastman Chemical CompanyInventors: Daniel Latham Terrill, Brian David McMurray, Damon Ray Billodeaux, James Lon Little, Adam Scott Howard

Patent number: 9227903Abstract: The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A method of reducing the isopropyl formate byproduct in the oxidation of isobutyraldehyde is described.

Patent number: 8809594Abstract: Disclosed is a process for the production of higher aldehydes from lower alcohols using a two-stage vapor phase heterogeneous catalyst system. Ethanol feeds afford aldehydes such as butyraldehyde and crotonaldehyde while butanol feeds yield 2-ethylhexanal and 2-ethylhexenal. Higher product selectivities are obtained when the alcohol is first dehydrogenated in the upper catalyst stage followed by aldol condensation of the resulting lower aldehyde to a higher aldehyde.Type: GrantFiled: September 21, 2012Date of Patent: August 19, 2014Assignee: Eastman Chemical CompanyInventors: David William Norman, Damon Ray Billodeaux, Melissa Dawn Page
