摘要:
A process for producing aliphatic amines which comprises reacting an aliphatic alcohol or an aliphatic aldehyde with an aminating agent selected from the group consisting of ammonia, a primary amine and a secondary amine in the liquid phase in the presence of an unsupported catalyst consisting essentially of (1) copper oxide or copper hydroxide and (2) an organo nickel compound.

A process for producing aliphatic amines which comprises reacting an aliphatic alcohol or an aliphatic aldehyde with an aminating agent selected from the group consisting of ammonia, a primary amine and a secondary amine in the liquid phase in the presence of an unsupported catalyst consisting essentially of (1) copper oxide or copper hydroxide and (2) a Group II A metal oxide or hydroxide. In a preferred embodiment the catalyst system also contains an organo nickel compound.
摘要:
Antioxidant additives for lubricating oils are prepared by reacting an acidic molybdenum compound or salt thereof and a basic nitrogen compound where the temperature of the process does not exceed 120° C., resulting in a product color that is light in intensity.
摘要:
Borated alkyl catechols can be stabilized by the addition of certain defined dialkylamines.Lubricating oils containing a borated alkyl catecholdialkylamine complex are effective in reducing oxidation, wear and deposits in an internal combustion engine.
摘要:
A process for alkylating an aromatic polyol, such as catechol, with an alpha olefin oligomer of alpha olefins having from about 8 to 14 carbon atoms or mixtures thereof using an organic sulfonic acid catalyst which is soluble under the alkylation reaction conditions. The liquid alkyl aromatic polyol product is useful as a lubricating oil additive or lubricating oil base stock.
摘要:
A process for producing carboxylic acids from olefins having from 20 to 24 carbon atoms or mixtures of olefins having from 20 to 24 carbon atoms which involves adding said olefin or mixtures of said olefins without a solvent to carbon monoxide and sulfuric acid and thereafter adding water to the reaction product so formed.
摘要:
Substituted acetylenes wherein the amino and acetylene groups are directly connected to aromatic ring carbon atoms and wherein the substituted acetylene has at least 3 carbon atoms and a hydroxyl group on the carbon atom adjacent to the acetylene group are claimed as new compositions of matter. The new compositions are prepared by the selective reduction of the corresponding nitroaromatic by contacting the nitroaromatic and free molecular hydrogen with a catalyst consisting essentially of ruthenium. A new process is also described for the preparation of an aminophenylacetylene.
摘要:
A stable impregnating solution of 3,3',4,4'-benzhydrol tetracarboxylic dianhydride and a polyepoxide for preparing handleable, formable resin-impregnated reinforcing material and fully cured laminates. A substantially non-reacted solution of 3,3',4,4'-benzhydrol tetracarboxylic dianhydride and a diglycidyl ether of bisphenol A is obtained in acetone.
摘要:
An improvement in the process wherein durene is subjected to liquid phase oxidation with aqueous nitric acid to obtain pyromellitic acid which involves subjecting durene to pretreatment with oxygen in the presence of a cobalt compound dissolved in a lower carboxylic acid.
