Method To Produce Cyclic Esters
US Patent:
5750732, May 12, 1998
Filed:
May 19, 1995
Appl. No.:
8/444954
Inventors:
Dan W. Verser - Golden CO
Alex Cheung - Fort Collins CO

Assignee:
Chronopol, Inc. - Golden CO
International Classification:
C07D32100, C07D32110
US Classification:
549274
Abstract:
Disclosed is a novel integrated process for production of cyclic esters which includes recovery of starting materials, such as lactic acid from a dilute aqueous lactic acid-containing solution, by solvent extraction. The starting materials are then formed into cyclic esters by removal of water wherein the concentration of higher molecular weight oligomers is maintained below about 20 wt % of the reaction composition. The process further includes providing a recovery solvent for the reaction composition and separating the cyclic esters from the starting materials and higher molecular weight oligomers by liquid-liquid equilibrium separation. The present invention is further directed toward independent novel unit operations of the overall process. The present invention provides for the efficient production and recovery of cyclic esters due to integration of the various unit operations by use of appropriate solvents and recycle streams. In addition, high rates of conversion of starting materials and high rates of selective production of cyclic esters are achieved by appropriate control of process parameters.

Energy Efficient Methods To Produce Products
US Patent:
2013018, Jul 25, 2013
Filed:
Nov 8, 2012
Appl. No.:
13/671817
Inventors:
Dan W. Verser - Menlo Park CA, US
Timothy J. Eggeman - Lakewood CO, US
Timothy J. Eggeman - Lakewood CO, US
Assignee:
ZeaChem, Inc. - Menlo Park CA
International Classification:
C12P 7/18
US Classification:
435158
Abstract:
The invention relates to processes that efficiently convert carbon-containing materials, such as biomass, into products in such a manner that the energy, carbon, and mass content of the materials are efficiently transferred into such products. Such methods include converting the materials into at least one intermediate by a biological conversion process and at least one intermediate by a thermochemical conversion process and reacting the intermediates to form the product. Such methods have a chemical energy efficiency to produce the product that is greater than the chemical energy efficiency of a solely biological conversion process to produce the product and that is greater than the chemical energy efficiency of a process in which all of the material is initially subjected to a thermochemical conversion step as part of the process to produce the product.
Method To Produce And Purify Cyclic Esters
US Patent:
5675021, Oct 7, 1997
Filed:
Apr 5, 1995
Appl. No.:
8/417597
Inventors:

Herman P. Benecke - Columbus OH
Assignee:
Chronopol, Inc. - Golden CO
International Classification:
C07D32100, C07D32110
US Classification:
549274
Abstract:
Methods are provided for the production, recovery and purification of cyclic esters. Such methods include producing a cyclic ester composition containing at least one impurity, contacting the cyclic ester composition with at least one adsorbent to remove the impurity and recovering the purified cyclic esters. Also included are methods of cyclic ester purification involving multiple adsorption operations. The methods of the present invention can produce highly purified cyclic esters. Such compositions are suitable for use in the manufacture of polymers having an average degree of polymerization in excess of about 1700.
Process For Producing Ethanol From Corn Dry Milling
US Patent:
7888082, Feb 15, 2011
Filed:

Timothy J. Eggeman - Lakewood CO, US
Assignee:
Zeachem, Inc. - Menlo Park CA
International Classification:
C12P 7/62, C12P 7/06
US Classification:
435135, 435161, 435162, 435165
Abstract:
A process for producing ethanol by the conversion of carbohydrates from a corn dry milling process in which the bottoms fraction from distillation of ethanol in a conventional yeast fermentation is used in a process including a combination of biochemical and synthetic conversions. The process results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from bottoms fraction, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts of the process include a high protein content solids fraction produced in the fermentation.
Recovery Of Organic Acids

US Classification:
562508, 562600, 562606, 562608
Abstract:
A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. A tertiary amine and COare introduced to the solution to form the insoluble carbonate salt and a complex between the acid and an amine. A water immiscible solvent, such as an alcohol, is added to extract the acid/amine complex from the dilute salt solution to a reaction phase. The reaction phase is continuously dried and a product between the acid and the solvent, such as an ester, is formed.
