Abstract
Abstract A process is disclosed which comprises the steps of introducing a stream of the organic liquid onto a plurality of rotating reacting surfaces, rotating the reacting surfaces at a velocity such that the organic liquid is continuously formed into a thin film on each reacting surface and is continuously moved as a thin film towards the periphery of each reacting surface by centrifugal force, depositing over each thin film a substantially undiluted stream of a gaseous medium, reacting the organic liquid and gaseous medium on said rotating reacting surfaces, maintaining the pressure during reaction at subatmospheric levels, moving the resulting reaction products in a radially outward direction along each reacting surface and collecting said reaction product. An apparatus for carrying out such process is also disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A REACTOR FOR REACTING A THIN FILM OF AN ORGANIC LIQUID WITH A GASEOUS MEDIUM COMPRISING: A REACTION CHAMBER VERTICAL PLANE AND TWO REACTING SURFACES A SUBSTANTIALLY VERTICAL PLANE AND TWO REACTING SURFACES INTERNAL OF SAID DISC AND FACING ONE ANOTHER: FIRST DEPOSITING MEANS TO DEPOSIT SAID ORGANIC LIQUID ON SAID REACTING SURFACES, ROTATING MEANS TO ROTATE SAID REACTING SURFACES AT A SPEED SUCH THAT SAID ORGANIC LIQUID IS CONTINUOUSLY FORMED INTO A THIN FILM ON EACH REACTING SURFACE AND IS CONTINUOUSLY MOVED TOWARDS THE PERIPHERY OF EACH REACTING SURFACE BY CENTRIFUGAL FORCE, SECOND DEPOSITING MEANS TO DEPOSIT A SUBSTANTIALLY UNDILUTED STREAM OF GASEOUS MEDIUM OVER WACH THIN FILM, COOLING MANS FOR COOLING EACH OF SAID REACTING SURFACES: MEANS TO MAINTAIN A SUBATMOSPHERIC PRESSURE BELOW ABOUT 100 MM HG IN SAID REACTION CHAMBER, AND
