Dr. Turton's main
research interests lie in the area of particle coating and the
application of this technique to the pharmaceutical and agricultural
industries. In particular, he has been involved in the quatification
of the uniformity of particle coating obtained in fluidized
bed batch coating operations. This research is particularly
important when an active igredient such as a drug is applied
(coated) onto the surface of large particles or tablets. The
accurate prediction of the tablet-to-tablet variation obtained
during a batch coating operation is essential to the production
process. In the future, this work will be extended to the coating
of tablets and particles in rotating drums or coating pans
In addition, Dr. Turton
has been involved in a number of projects in the area of process
synthesis. Recently, he has been involved in developing process
alternatives for the conversion of coal to higher alcohols and
fuel additives, and currently is working on developing alternative,
environmentally friendly ("green") process routes for existing
chemical products.
Dr. Turton is also
lead author of the book "Analysis, Sunthesis, and Design of
Chemical Processes" by R. Turton, R.C. Bailie, W.B. Whiting,
and J.A. Shaeiwitz, Prentice-Hall, Upper Saddle River, NJ, 1997.
