Process for fluorination of aromatic and polynuclear hydrocarbon compounds and fluorocarbons produced thereby

Abstract

Abstract A PROCESS FOR THE DIRECT FLUORINATION OF CYCLIC HYDROCARBON COMPOUNDS, AND THE PRODUCTION OF NEW PERFLUOROPERHYDRO DERIVATIVES THEREOF. THE CYCLIC HYDROCARBON COMPOUND IS FIRST PLACED IN A REACTION CHAMBER AND FLUORINE GAS OR AN INORGANIC FLUORIDE GAS IS INTRODUCED INTO THE ATMOSPHERE SURROUNDING SAID COMPOUND AT A SLOW RATE SUCH THAT THE INITIAL CONCENTRATION OF THE FLUORINATING GAS IS A MERE TRACE AND SUCH CONCENTRATION IS LESS THAN 6% AT THE END OF THIRTY MINUTES OF FLUORINATION. THE INTRODUCTION OF THE FLUORINATING GAS IS THEN CONTINUED AT A SLOW RATE TO GRADUALLY INCREASE THE CONCENTRATION THEREOF IN SAID ATMOSPHERE UNTIL THE CONCENTRATION OF THE FLUORINATING GAS IS ABOUT 100%. THE FLUORINATION PROCESS IS PREFERABLY CONDUCTED AT ATMOSPHERIC PRESSUE AND ROOM TEMPERATURE; HOWEVER, HIGHER TEMPERATURES UP TO THE DECOMPOSITION TEMPERATURES OF THE MATERIAL MAY BE USED AND IN ORDER TO INCREASE THE AMOUNT OF FLUORINATION, PRESSURES ABOVE ATMOSPHERIC MAY BE USED AFTER A PRELIMINARY ATMOSPHERIC FLUORINATION. NEW PERFLUOROPERHYDRO DERIVATIVES OF CYCLIC HYDROCARBONS WHICH HAVE BEEN PRODUCED BY USING THIS PROCESS INCLUDE PERFLUOROPERHYDRONAPHTHACENE, PERFLUOROPERHYDROPENTACENE, PERHYDROOVALENE, PERFLUOROPERHYDRO - 9,10 - BENZAPHENANTHRENE, PERFLUOROPERHYDRO-1,2BENZANTHRACENE, AND PERFLUOROPERHYDRO-1,3,6,8-TETRAPHENYLPYRENE.
