    摘要: Benzene and n -butene (1-, cis - and/or trans -) are reacted at a temperature of 20 to 70°C in the presence of a complex catalyst which is a homogeneous liquid of aluminum chloride, hydrogen chloride and an aromatic hydro­carbon, in amount of 0.3 to 5 wt% of the AlCl₃ to the benzene (prepared by stirring for ⅓ - 3 hours); the reaction mixture is separated into fractions containing mainly the desired product sec -butylbenzene with not more than 1% of by-product isobutylbenzene; heavy materials; and (which are recycled) benzene, and dibutyl- and tributylbenzenes.
    The catalyst can be separated, recovered and recycled.
    The reaction can be continuous or batchwise.
    The product sec -butylbenzene can be utilised for production of phenol.

    摘要: A mixture of (a) highly unsaturated hydrocarbons having at least 2 double bonds or at least 1 triple bond (e.g. 1,3-butadiene, propadiene, vinylacetylene) and (b) hydrocarbons having 4 or more C atoms (e.g. butane, butene) is contacted in a fixed bed reactor containing a catalyst, e.g. palladium, with hydrogen gas in amount of 1 to 3 moles per mole of unsaturated hydrocarbons (a); the H 2 is supplied at at least two, preferably two or three, points along the length of the vessel.
    Two or more vessels can be connected in series, or a single vessel can be divided into separate catalyst zones between which H 2 is fed. Reaction in vapour phase is preferred.
    The method provides hydrogenation of the highly unsaturated hydrocarbons, without isomerization of olefinic double bonds which can reduce the proportion of 1-butene.

    摘要: A process for producing a high purity caprolactam is disclosed in which a crude caprolactam obtained by a catalytic rearrangement of cyclohexanone oxime is subjected

    (1) to mixing, while stirring, with at least one hydrocarbon selected from the group consisting of aliphatic hydrocarbons and alicyclic hydrocarbons to form a liquid-liquid , two-layer liquid mixture, and then crystallizing caprolactam out of the liquid mixture;
    (2) to mixing with both at least one hydrocarbon selected from the group consisting of aliphatic hydrocarbons and alicyclic hydrocarbons, and water to form a liquid mixture, separating the liquid mixture into a hydrocarbon layer and a water layer, and then recovering caprolactam from the water layer; or
    (3) to distillation in the co-presence of at least one aliphatic saturated hydrocarbon of 10 to 18 carbon atoms.
