A process for producing a polyether polyol with a content of 0.5 to 99.5% by weight of oxytetramethylene groups derived from tetrahydrofuran by copolymerizing tetrahydrofuran or a mixture of tetrahydrofuran and another cyclic ether copolymerizable therewith with a polyhydric alcohol having two or more hydroxyl groups per one molecule with the use of a heteropoly-acid and/or its salt as a catalyst, which comprises allowing 0.1 to 15 molecules of water per one heteropoly-anion to exist in the catalyst phase. The above-described polyether polyol is an industrially useful polymer which is a starting material for polyurethane to be used for spandex or a synthetic leather, etc.

Process for producing polyether polyol and a product

Homogeneous lubricant blends are disclosed comprising polyether liquid lubricants miscible with synthetic hydrocarbon fluids or severely hydroprocessed basestock. The lubricants comprise SHF or hydroprocesed basestock and polyalkylene oxide polymer having recurring units of at least one long chain monoepoxy alkane monomer(s) containing 8 to 30 carbon atoms and short chain comonomer(s) selected from the group consisting of substituted or unsubstituted tetrahydrofuran, oxetan, butylene oxide propylene oxide and ethylene oxide wherein the mole ratio of long chain monoepoxy alkane monomers to short chain comonomers is between .5 and 9.

Polyether fluids miscible with non-polar hydrocarbon lubricants

Certain polyalkylene glycols, useful as lubricant additives, are soluble with all four types of hydrocarbon base oils (Groups I-IV) at a wide variety of ratios of oil to polyalkylene glycol and under a variety of conditions. These polyalkylene glycols are prepared by reacting a C8-C20 alcohol and a mixed butylene oxide/propylene oxide feed, wherein the ratio of butylene oxide to propylene oxide ranges from 3:1 to 1:1. The invention provides a means of providing desirable lubricant compositions which may pose fewer environmental problems.

Novel oil-in-ol emulsions and methods of lubrication using the same are provided. The lubricants are stable emulsions of carrier fluid and high viscosity fluid that display superior properties related to lubricating film thickness and reduced shear strenght.

Oil-in-oil emulsion lubricants for enhanced lubrication

A peroxygen bleaching composition which comprises approximately by weight a mixture of about 1 to about 75% of an inorganic peroxygen bleaching compound; and about 1 to about 75% peroxygen ketalcycloalkanedione bleachant activator.

Polyethers obtainable by polymerisation of ethylene oxide and/or propylene oxide or butylene oxide, an alpha -alkylene oxide, tetrahydrofuran and in the presence of a bifunctional compound, can be used as lubricants.

Polyethers, their preparation, and their use as lubricants

Certain spirocyclic ketals of the formula ##STR1## in which R 1 in the case where R 2 denotes hydrogen, represents a cyclohexyl radical optionally substituted by lower alkyl, lower alkoxy and/or cycloalkyl with 5 to 7 carbon atoms, or in which R 1 and R 2 are linked through 4 methylene groups, which are optionally substituted by lower alkyl, lower alkoxy and/or cycloalkyl with 5 to 7 carbon atoms and form a further acyclic ring. R 3 , R 4 and R 5 are identical or different and denote hydrogen, lower alkyl, lower alkoxy or cycloalkyl with 5 to 7 carbon atoms, and Z denotes alkylene with 2 to 4 carbon atoms which is optionally substituted by lower alkyl and/or cycloalkyl with 5 to 7 carbon atoms, are disclosed together with their use in power transmission fluids.
