Improvements in or relating to the manufacture and production of lubricating oils

In the reaction of aromatic hydrocarbons with halogenated aliphatic hydrocarbons in the presence of ordinary or activated aluminium or an aluminium halide, the separation of the catalyst from the crude product, or from the layers into which the crude product may separate, is effected by treating the crude product or the separated layers (a) at a raised temperature with ammonia, or (b) at a temperature not below about 200 DEG C. with a substantially anhydrous halide, sulphate or phosphate of a metal of the first or second periodic group (including ammonium) or with an oxide or hydroxide of a metal of the second periodic group; the mixture is then filtered or decanted. When treatment (a) is applied, the treatment may be begun at atmospheric temperature and may be effected either by passing ammonia into the material or by adding a solution of ammonia in a solvent such as benzene or toluene; the use of alcoholic ammonia is excluded, and the use of aqueous ammonia is not recommended.

A process for producing lubricating oils, insulating oils and similar viscous oils

The oxidation stability of viscous synthetic hydrocarbon oils for use, e.g. as lubricants or insulating oils, is increased by adding thereto extracts obtained from natural hydrocarbon oils boiling above about 300 DEG C., or fractions thereof, by the use of selective solvents, which extracts have been refined by selective hydrogenation. The synthetic hydrocarbons are products obtained from unsaturated or aromatic hydrocarbons by polymerization or condensation, e.g. by the polymerization of vapour phase cracked products of paraffin wax or paraffinous materials, or by the condensation of olefines or chloroparaffins with aromatic hydrocarbons. The polymerization or condensation may be effected either chemically in the presence of aluminium chloride, boron p fluoride or a similar agent, or by voltolization. The extracts are obtained, preferably from a heavy mineral oil fraction, by selective solvents for constituents other than paraffins, such as liquid sulphur dioxide, nitrobenzene furfurol ...

The aliphatic hydrocarbons preferably consist wholly or mainly of paraffin wax, which in turn is preferably pre-halogenated. Preferably 0,1-5 per cent of the isocyclic compounds and 5-20 per cent of the cyclic compounds are employed.

Composition and methods for injection of sealants into air conditioning and refrigeration systems

The use of sealants based on organosilanes for refrigeration and air conditioning systems is made possible by control of the rate of introduction and viscosity of the sealant mixture within certain ranges. An appropriate choice of organosilane sealant is made to allow effective sealing of small pinhole size leaks in the air conditioning or refrigeration system. The organosilane is then combined with a miscible lubricant at particular ratios to provide the proper mixture viscosity for injection into the refrigerant system to prevent bearing seizure. Specific orifice sizes are selected for an apparatus to ensure that the composition is injected at the flow rates required to prevent liquid slugging and subsequent compressor shutdown or failure. In addition, effective introduction of the mixture requires certain procedures be performed. Injection procedures are also described that prevent temporary or catastrophic equipment shutdown.
