Dr. Ronald W. Rousseau, School of Chemical & Biomolecular Engineering Chair & Cecil J. "Pete" Silas Chair, will be the speaker at the 28th Annual Ashton Cary Lecture on April 24-25. The Keynote Address will be on Wednesday, April 24, from 4-5 p.m. in the "M" Building, Room G011. The Special Lecture will be on Thursday, April 25, at 11 a.m. in ES&T L1255.
Routes to Chiral Purity Involving Crystallization
Chiral purity has become an increasingly important characteristic of many specialty chemicals, especially pharmaceuticals. Manufacturers seeking chiral purity have two choices: (1) utilize syntheses that directly yield such purity or (2) separate and purify a desired stereoisomer from a mixture containing two or more isomers. This presentation will highlight the use of crystallization in meeting the challenges of such separations. Particular emphasis will be given to the role of nucleation in determining the identity of the species produced and to controlling system conditions so that nucleation and growth mechanisms may be manipulated to influence the process outcome.
The Cary Lecture Series in the School of Chemical & Biomolecular Engineering was established in 1984 as a memorial to Ashton Hall Cary, a chemical engineering graduate of Georgia Tech, Class of 1943. Mr. Cary served in the U.S. Army after graduation and later built a career in Georgia’s textile industry. He was a native of LaGrange, Georgia, where he was prominent in local politics and business and active in many charitable and civic organizations. At the time of his death in 1983, Mr. Cary was a production consultant for Kleen-Tex Industries.
The Cary Lecture Series was initiated with a gift from Dr. Freeman Cary, who also studied chemical engineering at Tech. Dr. Cary, who is Ashton’s brother, received his M.D. from Emory University in 1950 and later became the attending physician for the U.S. Congress.The Cary Lectureship Fund is used to sponsor a lecture series by distinguished scholars in fields of significance to chemical engineering. The visiting lecturers, in addition to presenting seminars on recent engineering advances, participate in informal discussions with Georgia Tech faculty and students.
