Abstract

L'INVENTION CONCERNE UN PROCEDE POUR L'OBTENTION DE TRICHLORURE DE BORE PAR CHLORATION DE BORATE. LE PROCEDE CONSISTE A REDUIRE LA QUANTITE DE PHOSGENE FORMEE EN METTANT LE BORATE EN CONTACT AVEC LE CHLORE DANS UN REACTEUR EN PRESENCE D'UN INITIATEUR DE RADICAUX LIBRES A DES TEMPERATURES COMPRISES ENTRE 20 ET 100C ENVIRON ET A EVACUER SIMULTANEMENT LES PRODUITS GAZEUX DE LA REACTION DE CHLORATION HORS DU REACTEUR, LE RAPPORT MOLAIRE DU CHLORE AU BORATE INTRODUIT DANS LE REACTEUR ETANT COMPRIS ENTRE 5, 5:1 ET 7,5:1 ENVIRON. APPLICATION: FABRICATION DE TRICHLORURE DE BORE.THE INVENTION RELATES TO A PROCESS FOR OBTAINING BORON TRICHLORIDE BY CHLORINATION OF BORATE. THE PROCESS CONSISTS OF REDUCING THE QUANTITY OF PHOSGENE FORMED BY PUTTING THE BORATE IN CONTACT WITH THE CHLORINE IN A REACTOR IN THE PRESENCE OF AN INITIATOR OF FREE RADICALS AT TEMPERATURES BETWEEN 20 AND 100C AND SIMULTANEOUSLY EVACUING THE GAS PRODUCTS FROM THE REACTION OF CHLORINATION OUTSIDE THE REACTOR, THE MOLAR RATIO OF CHLORINE TO BORATE INTRODUCED INTO THE REACTOR IS BETWEEN APPROXIMATELY 5, 5: 1 AND 7.5: 1. APPLICATION: MANUFACTURE OF BORON TRICHLORIDE.
