A process for the preparation of liquid ketones which comprises coupling a saturated aldehyde, e.g., acetaldehyde, with an alpha-olefin, e.g., ethylene, in the presence of an organic hydroperoxide initiator and a metal-containing compound as the catalyst therefor, e.g., cobalt(II) acetylacetonate. The novel process results in good productivities and high initiator efficiencies.

Amides are prepared by contacting phosgene with a mixture of an organic compound containing at least one active hydrogen atom, as determined by the Zerewitinoff method and an acid salt of an amine, wherein said acid has a pK.sub.a value not substantially above about 6.

Compounds containing both an ethylenic and an acetylenic linkage may be prepared by dehydrochlorination of chloro-substituted unsaturated compounds such as alkenes or alkadienes.

Resin-bonded composite materials having improved high temperature characteristics are provided by utilizing theta solvents for the resin.

A process for the preparation of aromatic compounds is set forth which involves contacting a feed consisting essentially of C.sub.2 -C.sub.4 paraffins and/or olefins with a crystalline aluminosilicate of the ZSM-5 type and recovering the aromatics produced. The described process can be carried out in the absence of a hydrogenation/dehydrogenation component and in the absence of added hydrogen.

High molecular weight linear thermoplastic elastomeric polyurethanes of I.V. 0.9-2 are prepared by reaction in solution. A hydroxyl-terminated prepolymer and a diol chain extender are reacted, in the solvent, with a small excess of diisocyanate, until the --NCO content becomes constant, then a diol chain extender in amount equivalent to the remaining --NCO; reaction is continued, and then terminated after the high I.V. is attained.

Method for forming ceramics and more particularly for fabricating screens for colored television tubes comprising coating a cathode ray tube faceplate with a solid, light-sensitive organic layer capable of developing a R.sub.d of 0.2 to 2.2, preferably a R.sub.dp of 0.4 to 2.0; exposing said light-sensitive organic layer to actinic radiation in image-receiving manner to establish a potential R.sub.d of 0.2 to 2.2; applying to said layer of organic material, free flowing phosphor particles having...

Improved selectivity of desired vinylated aromatic compounds may be obtained when aromatic compounds are treated with an ethylenic compound in the presence of certain metallic catalysts by effecting the reaction in an acidic solvent medium, the dielectric constant of said solvent being less than 6.15.

A new process for preparing hydroxyquinolines from aminoquinolines via an aqueous acid hydrolysis of the aminoquinoline to the hydroxyquinoline.

The invention is concerned with a new process for preparing 7-hydroxy dihydrocitronellal. This process consists in causing citronellal to react with a secondary amine, in transforming the derivative obtained, by treatment in aqueous acid medium, into the immonium of the citronellal, which is hydrated, then in hydrolysing the immonium of the hydroxycitronellal thus formed into 7-hydroxy dihydrocitronellal, all these operations being effected in the liquid base.
