Patent number: 6288291Abstract: A process for fluorinating a hydrocarbon substrate by mixing it with an inert diluent and mixing the diluted substrate with a gaseous fluorinating reagent to form a foam reaction mixture. The fluorinating reagent reacts with the substrate in the form to foam product. The foam is separated into a liquid component which contains product and a gas component. Product is withdrawn from the liquid component which is then returned to the diluting step. Fluorinating reagent is fed into the gas component which is then recirculated to the mixing step.Type: GrantFiled: May 18, 2000Date of Patent: September 11, 2001Assignee: South Africa Nuclear EnergyInventors: Driekus Van Der Westhuizen, Petrus Johannes Venter
