Abstract: 1. A PROCESS FOR THE MANUFACTUREOF BETA, BETA''-BIS-(3, 5-DICHLORO-4 - HYDROXYPHENYL)-PROPANE COMPRISING THE STEPS OF ADDING GASEOUS CHLORINE TO BETA,BETA''-BIS-(4-HYDROXYPHENYL)-PROPANE WHICH IS DISSOLVED IN METHANO, AT WORKING TEMPERATURES NOT EXCEEDING 20*C. AND IN THE PRESENCE OF (A) AT LEAST ONE SUBSTANCE HAVING A CATALYTIC EFFECT ON THE CHLORINATION REACTION, SAID SUBSTANCE BEING A METAL CHLORIDE SELECTED FROM THE GROUP CONSISTING OF IRON AND COPPER CHLORIDES, AND (B) AT LEAST ONE SUBSTANCE HAVING AN INHIBITING EFFECT ON FREE RADICAL REACTIONS, SAID SUBSTANCE BEING AN ANTIOXIDIZING AGENT SELECTED FROM THE GROUP CONSISTING OF CRESOLS, THIOCRESOLS, P-TERBUTYL-CATECHOL, HYDROQUINONE AND THE PRODUCTS OF CONDENSATION OF CROTONALDEHYDE WITH 3-METHYL-6-TERBUTYLPHENOL, CONTINUING SAIDCHLORIDE ADDITION UP TO A QUANTITY AT LEAST EQUAL TO THE STOICHIOMETRIC QUANTITY FOR THE CHLORINATION REACTION, AND RECOVERING BETA, BETA''-BIS - (3,5-DICHLORO - 4-HYDROXYPHENYL)-PROPANE FROM THE PRODUCTS OF THE CHLORINATION REACTION.

Abstract: The liquid aluminium trichloride-hydrocarbon complex formed from a catalytic process is reactivated by instantaneously vaporizing it under conditions such as to form no more than 25 wt. percent of normally gaseous products, e.g., at atmospheric pressure and 300* to 500* C, and the vaporized products are condensed and the normally liquid catalytic products are recovered. The complex can be used for catalysing the alkylation of benzene with propylene tetramer.

Abstract: AROMATIC HYDROCARBONS ARE SEPARATED FROM A MIXTURE OF LIQUID HYDROCARBONS. THE MIXTURE OF LIQUID HYDROCARBONS IS EXTRACTED IN THE LIQUID PHASE IN AN EXTRACTION ZONE AT A TEMPERATURE FROM ABOUT 40*C. TO AOUT 80*C. WITH ETHYLENEDIAINE SOLVENT HAVING A WATER CONTENT OF FROM 00% TO 20% BY WEIGHT TO FORM AN EXTRACTED PHASE AND A RAFFINATE PHASE. THE EXTRACTED PHASE COMPRISES PREDOMINANTLY AROMATIC HYDROCARBONS, SOLVENT AND A MINOR AMOUNT OF NON-AROMATIC HYDROCARBONS. THE RAFFINATE PHASE COMPRISES PREDOMINANTLY NON-AROMATIC HYDROCARBONS. THE EXTRACTED PHASE AND THE RAFFINATE PHASE ARE SEPARATELY COLLECTED. THE EXTRACTED PHASE IS COLLED TO A TEMPERATURE AT LEAST 300*C. LOWER THAN THE TEMPERATURE OF THE EXTRACTION STEP AND THEN SEPARATED INTO A HEAVIER SOLVENT CONTAINING PHASE AND ALIGHTER HYDROCARONS CONTAINING PHASE. THE NON-AROMATIC HYDROCARBONS IN THE LIGHTER HYDROCARBONS CONTAINING PHASE ARE SEPARATED A OVERHEAD PRODUCT BY MEANS OF EXTRACTIVE STRIPPING AT ATMOSPHERIC PRESSURE. THE AROMATIC HYDROCARBONS REMAIN IN THE RESIDUE OF THE EXTRACTIVE STRIPPING WHICH IS THEN SCRUBBED WITH WATER TO THEREBY OBTAIN AN AROMATIC HYDROCARBONS PHASE AND AN AQUEOUS ETHYLENEDIAMINE CONTAINING PHASE. THE AROMATIC HYDROCARBONS PHASE IS THEN RECTIFIED.
