Title: Process for the production of detergent alkylate
IPC: C07C15/107
Filed: 1963-10-28
Abstract: Detergent alkylate is obtained by dimerizing propylene in the presence of cobalt on activated carbon, separating n-hexenes from the product, catalytically dimerizing the n-hexenes, separating a fraction in the C10-C16 range and condesing this with an aromatic hydrocarbon.  The first dimerization is effected at 20-200 DEG  C. and sufficient pressure to maintain liquid phase, e.g. 300-1000 p.s.i.g., using a catalyst containing 1-30% wt. of cobalt and a feed free from sulphur compounds, carbon monoxide, oxygen and acetylenes. The n-hexenes are separated by molecular sieve, urea adduction or preferably distillation as the amount of 2-methylpentene-2 formed is low.  The second dimerization is effected at 60-250 DEG  C. and a pressure up to 2000 p.s.i.g. to maintain the liquid phase using a catalyst comprising a transition metal oxide, e.g. manganese oxide, supported on silica or silica/alumina or a hydride of Be, Al, Ga or In or a derivative thereof having alkyl or aryl radicals in place of one or more hydrogen atoms, modified if desired by the inclusion of a trialkyl borane copper or a transition metal of Groups III-VIII or are ducible compoundthereof. Benzene, xylene orn aphthalene may be alkylated with the product in the presence of aluminium chloride, boron trifluoride or anhydrous hydrogen fluoride, at - 20 to 100 DEG C.  A detergent alkylate fraction is recovered by distillation, sulphonated and neutralized.  Reference has been directed by the Comptroller to Specification 983,376.

Abstract: Rare-earth suboxides (of La, Pr, Pm, Gd, Dy, Ho, Er, Lu and Y) which are oxygen-deficient relative to the sesquioxide, are dark-coloured, highly magnetic, and electrically semi-conducting. The following have been prepared: GdO1.495, ErO1.489, HoO1.490, LuO1.465, YO1.491. Their resistivity can be lowered by the incorporation of conducting metals, e.g. Ag, Cu. Incorporation (e.g. of copper or silver oxalate) may be combined with the production of the suboxides.  Preparation is by partial decomposition of higher oxides in a high vacuum, e.g. 5x10-6 torr. or reducing atmosphere at elevated temperatures or by arc-melting or furnace-heating at 2250-2500 DEG  C. a mixture of the sesquioxide and a metal, e.g. same rare-earth as suboxide to be prepared, another rare-earth or iron, copper or nickel.  Excess metal is then dissolved by hydrochloric acid. Alternatives are the vacuum-heating of compacted sesquioxide-hydride mixture at 800 DEG C. then heating at 2000 DEG  C. in argon, and drying a mixture of the oxalate and another oxalate at 200 DEG  C. in He, heating to 300 DEG C. in He, and to 1400 DEG  C. in H2.  These suboxides may be used in the microwave field and for magnetic cores, as semi-conductors, thermoelectric generators and as elements in lasers.
