Methods For The Manufacture Of Acetals And Ketals, And The Acetals And Ketals Produced Thereby

US Patent:
2012003, Feb 9, 2012
Filed:
Aug 3, 2011
Appl. No.:
13/197593
Inventors:
Brian D. Mullen - Delano MN, US
Marc D. Scholten - Saint Paul MN, US
Andrew J. Louwagie - Golden Valley MN, US
Steven A. Donen - Chanhassen MN, US
Feng Jing - Snellville GA, US
Vivek Badarinarayana - St. Louis Park MN, US
Assignee:
SEGETIS, INC. - Golden Valley MN
International Classification:
C07D 317/30
US Classification:
549205, 549454
Abstract:
A method for producing a product that comprises glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate comprises reacting either glycerol or propylene glycol with ethyl levulinate in the presence of a homogenous or heterogeneous catalyst system in a reactor system. The ethyl levulinate and either glycerol or propylene glycol are heated to remove water, polyol, and excess ethyl levulinate. The excess ethyl levulinate and polyol is recycled back to the reactor. The product is distilled in a specific fashion and optionally treated by means of a stabilizing agent or acid species removal bed, to obtain a composition comprising glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate wherein the composition comprises less than or equal to about 2 wt % contaminants.

Assignee:
SEGETIS, INC. - Golden Valley MN
International Classification:
C08K 5/1565, C08L 67/04, C08L 27/06, C08L 23/00, C08L 69/00, C08L 79/08, C08L 25/06, C08L 77/00, C08L 1/02, C08L 81/04, C08L 81/06, C07D 407/12, C08L 83/04
US Classification:
1062033, 549448, 524108
Abstract:
Disclosed herein is a polyketal adduct obtained by forming an ester between a hydrocarbon polyol and a ketocarboxylic acid to produce an intermediate polyketocarboxylic ester. The intermediate polyketocarboxylic ester can be purified via crystallization to achieve purities of greater than 99.0% and then ketalized to produce the polyketal adduct, which can be used in polymer compositions. The polyketal adduct I is obtained at high purity and at high yield.

Abstract:
Disclosed herein is a polyhydroxy ketal adduct obtained by the esterification of a hydrocarbon polyol by at least 1.5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. The intermediate polyketocarboxylic ester is then ketalized to produce the polyhydroxyketal adduct, which can be used to provide a polymeric composition.

Abstract:
Various esterified alkyl ketal ester or hydroxyalkyl ketal ester products are useful as components of organic polymer compositions. The ketal esters are produced in certain transesterifications between alkyl ketal esters and/or hydroxyalkyl ketal esters and polyols, aminoalcohols, polyamines and/or polycarboxylic acids. The products are excellent plasticizers for a variety of organic polymers, notable poly(vinyl chloride) plastisols. The products are also very good lubricants for many lubrication applications.
