A catalytic hydrogenation process for preparing alkyl-1,3-diaminopropanes by contacting an alkyl aminopropionitrile in the liquid phase with hydrogen and ammonia in the presence of a non-reactive organic solvent and a hydrogenation catalyst, the process conducted at a rising reaction temperature (.DELTA.T) along with the progressive vaporization of the solvent.

Catalytic hydrogenation process

A method of preparing acylisoxazolines by contacting an alkene with dinitrogen tetroxide and oxygen in the presence of a denitrating agent and calcium oxide.

Preparation of acylisoxazolines

An alkylene oxide adduct of phosphosulfurized N-(hydroxyalkyl) alkenylsuccinimide characterized by the formula: ##STR1## where R.sup.1 is alkenyl of from 10 to 30 carbons and X and Y are divalent saturated aliphatic hydrocarbon radicals of from 2 to 6 carbons. In addition, automatic transmission fluid compositions and concentrates thereof comprising a major amount of a lubricating oil and a friction modifying amount of the alkylene oxide adduct and method of operating an automatic transmission having friction sensitive power transmitting means employing the aforedescribed automatic transmission fluid composition.
