Develop an interactive computer program that determines the coefficient of performance of a Joule-Thomson refrigeration system using air or carbon dioxide (allow the user to choose which).
Curve fit the information given in given Figure as the source of the proper Joule-Thomson coefficient. Prompt the user for the appropriate temperatures, pressures, and isentropic compressor efficiency.
In the Gatterman-Koch reaction, a formyl (-CHO) group is introduced directly onto a benzene ring. For example, reaction of toluene with CO and HCl in the presence of mixed CuCl/AlCl3 gives p-methylbenzaldehyde. Propose a structure for the reactive..
