1. IN A PROCESS FOR THE OXIDATION OF SECONDARY AND TERTIARY ALKYL AROMATIC HYDROCARBONS WITH OXYGEN OR AN OXYGEN-CONTAINING GAS AT TEMPERATURES OF FROM 80* TO 130* C. IN THE PRESENCE OF A CATALYST TO PRODUCE THE CORRESPONDING HYDROPEROXIDE COMPOUNDS, THE IMPROVEMENT WHICH COMPRISES OXIDIZING SAID ALKYL AROMATIC HYDROCAR: BONS HAVING THE FORMULA
R1-CH(-R)-AR
IN WHICH R IS A LOWER ALKYL GROUP HAVING FROM ONE TO SEVEN CARBON ATOMS; R1 IS HYDROGEN OR A LOWER ALKYL GROUP HAVING FROM ONE TO SIX CARBON ATOMS; R AND R1, TAKEN TOGETHER, FORM A CYCLOALKYL RING HAVING FROM FOUR TO SEVEN CARBON ATOMS; AND AR IS PHENYL OR NAPHTHYL, IN THE PRESENCE OF A CATALYST COMPRISING A CUPROUS HALIDE SELECTED FROM THE GROUP CONSISTING OF CUPROUS CHLORIDE, CUPROUS BROMIDE, AND CUPROUS IODIDE, AND AN AROMATIC HETEROCYCLIC AMINE SELECTED FROM THE GROUP CONSISTING OF PYRIDINE, QUINOLINE, ISOQUINOLINE, TRIAZINE AND PYRAZINE, WHEREIN THE RATIO OF CUPROUS HALIDE TO AMINE IS IN TTHE RANGE OF ABOUT 1 TO 100 PARTS BY WEIGHT OF SAID HALIDE FOR EACH 100 PARTS OF AMINE.
摘要:
COPPER POLYPHTHALOCYANINE WHICH HAS BEEN ACTIVATED BY CONTACT WITH AN AROMATIC HETEROCYCLIC AMINE TO FORM A NOVEL COMPLEX IS FOUND TO BE AN EFFECTIVE CATALYST FOR THE OXIDATION OF SECONDARY AND TERTIARY ALKYL AROMATICS SUCH AS ETHYLBENZENE OR CUMENE TO FORM THE CORRESPONDING HYDROPEROXIDE. THE RATE OF CONVERSION AND THE PERCENTAGE YIELD IS GREATER THAN THAT WITH COPPER PHTHALOCYANINE OR COPPER POLYPHTHALOCYANINE PER SE.
摘要:
HYDROCARBON HYDROPEROXIDES ARE PRODUCED BY OXIDISING A HYDROCARBON HAVING AT LEAST ONE SECONDARY OR TERTIARY CARBON ATOM, FOR EXAMPLE CUMENE, IN THE LIQUID PHASE WITH A GAS CONTAINING FREE OXYGEN IN THE PRESENCE OF A FLUORIDE OF AN ALKALI OR ALKALINE EARTH METAL, PARTICULARLY SODIUM FLUORIDE.
摘要:
Hydroperoxides of alkylaromatic compounds are prepared by contacting the alkylaromatic compounds having at least one alkyl or cycloalkyl substituent group having a tertiary carbon atom in the Alpha -position with respect to the aromatic nucleus, with oxygen or a molecular oxygen-containing gas in the presence of 0.001 to 10 percent by weight of molybdenum disulfide at room temperature to 200*C. for 1 to 100 hours.
摘要:
METHOD FOR THE TREATMENT OF CUMENE HYDROPEROXIDE FOR USE IN EPOXIDATION REACTIONS BY DILUTING THE CUMENE HYDROEROXIDE WITH A HYDROCARBON WITH FORMS AN AZEOTROPE WITH WATER, WASHING THE DILUTED CUMENE HYDROPEROXIDE AND REMOVING THE HYDROCARBON-WATER-AZEOTROPE.
摘要:
TERTIARY-ALKYL HALOCUMYL PEROXIDES OF THE FORMULA
((X)N,R(5-N)-PHENYL)-C(-CH3)2-O-O-R1
WHEREIN X IS F, CL, OR BR; N=1-5; R IS H, ALKYL, CYCLOALKYL, OR ARYL; AND R1 IS TERTIARY-ALKYL OF 4-8 CARBON ATOMS. THESE PEROXIDES ARE USEFUL FOR CROSSLINKING POLYMERIC MATERIALS WITHOUT PRODUCING AN OBJECTIONABLE ODOR.
摘要:
This invention relates to the oxidation of alkyl aromatic compounds with an alkyl-substituted phthalocyanine as a catalyst and with methods for the preparation of this catalyst.
