Production of bis(alpha-alkylbenzyl)ethers or substituted derivatives thereof by reaction at elevated temperature of the corresponding alpha alkylbenzyl alcohols in the presence of a particular acidic clay catalyst, quenching of the catalyst and recovery of the desired ether by distillation directly from the reaction mixture containing the quenched catalyst, is disclosed. The alkyl methylbenzyl alcohol may be present as a component of an aromatic rich distilland product mixture derived from the ethyl benzene hydroperoxide epoxidation of an olefinically unsaturated compound.

Production of bis(alpha-alkylbenzyl)ethers

Improved polyimide and/or polyamide-imide coating compositions are provided for use as magnet wire coatings which comprise a polyimide and/or polyamide-imide polymer and a co-solvent mixture of N-methyl pyrrolidone and acetophenone the solids content of the solution being between about 5 percent and 40 percent by weight based on the total weight of solution.

Polyimide and/or polyamide-imide compositions in mixed solvents

Separating carbon monoxide from mixed gases containing the same with an adsorbent which is the product of heating a mixture of ferrous acetate and polyacrylonitrile in a ratio of ferrous acetate to polyacrylonitrile of 0.5:1.0 to 2.0:1.0 at a temperature of about 200.degree.-400.degree. C. in an oxygen-containing atmosphere for from about 2 to 10 hours.

Thermally condensed mixture of polyacrylonitrile and ferrous acetate as

A low viscosity synthetic lubricant is prepared by polymerizing 1-butene to an oligomer containing a number average of about 8 to 18 carbon atoms and copolymerizing the oligomer with an alpha-monoolefin having 8 to 18 carbon atoms to produce a copolymer having an average of about 20 to 40 carbon atoms. Both polymerization reactions are catalyzed by a combination of boron trifluoride and a proton donor promoter. The synthetic lubricant is preferably stripped to remove lower boiling components, such as oligomers having 20 carbon atoms or less, and optionally hydrogenated for improved stability.
