Propylene glycol (PG) and ethylene glycol (EG) are recovered from aqueous solution via reaction with acetaldehyde to form acetals in a reactive distillation column. The reaction takes place over Amberlyst 15 cationic exchange resin catalyst, held in structured packing in the column reactive zone. ...
This paper describes the results of laboratory testing comparing the heat transfer performance of heavy duty radiators with Propylene Glycol and Ethylene Glycol based coolants. Solutions of 50/50 Propylene Glycol/ water (50/50 PG/water) and 50/50 Ethylene Glycol/water (50/50 EG/water) were tes...
