  • Method for making an oxirane
    Patent number: 6380407
    Abstract: Continuous process for manufacturing an epoxide, according to which an olefin is reacted, in a reactor in the liquid phase, with a peroxide compound in the presence of a zeolite-based catalyst and in the presence of a solvent, and a gaseous compound is introduced continuously into the reactor at a flow rate which is sufficient to entrain at least some of the epoxide produced, which is recovered with the gaseous compound at the point at which it leaves the reactor.

  • Adjuvants for vaccines
    Patent number: 6340464
    Abstract: Vaccine adjuvants comprising a liquid medium contain polymers with anionic constitutive repeating units and hydrophobic constitutive repeating units. Advantageously, the adjuvants are aqueous solutions of partially esterified polyacrylic acids. The novel adjuvants are highly stable, effective and have a relatively low level of local toxicity. Further, vaccines comprising such adjuvants and a process for producing them are described.

  • Catalytic composition and process for the oxychlorination of ethylene using such a composition
    Patent number: 5527754
    Abstract: Catalytic composition comprising copper chloride, magnesium chloride and caesium chloride deposited on an alumina, which may be used in particular for the oxychlorination of ethylene into 1,2-dichloroethane. In the processes for the oxychlorination of ethylene in oxygen in a fluid bed, this catalytic composition makes it possible to obtain an excellent yield of 1,2-dichloroethane without causing the deposition of soiling material on the surface of the bundle of tubes of the heat exchanger located in the reactor.

  • Process for the oxychlorination of ethylene and catalyst compositions for the oxychlorination
    Patent number: 5315051
    Abstract: The invention relates to a process for the oxychlorination of ethylene by means of a catalyst composition comprising an alumina support impregnated with cupric chloride, magnesium chloride and a chloride of an alkali metal chosen from sodium and lithium. The oxychlorination performed in this manner makes it possible to obtain an excellent yield without the reactor being corroded by the catalyst composition employed.
