Abstract: A method for separating primary and secondary amines by contacting a mixture thereof with mesityl oxide, which forms acetone and an adduct with the primary amine. Acetone is removed to force the reaction. The reaction is particulary useful for separating close boiling amines. The primary amine adducts have high boiling points, thereby allowing the secondary amine to be recovered in high purity by distillation. The primary amine may also be recovered by hydrolyzing the adduct which produces the primary amine and acetone.

Abstract: Disclosed are novel cyclic terpenoid amines which can be prepared by cyclizing the corresponding acyclic terpenoid amine.

Abstract: Tertiary amines such as alkyl or benzyl amines are catalytically oxidized by oxygen over an activated carbon catalyst to selectively produce secondary amines.

Abstract: Ammonia or an amine such as morpholine is recovered from a resin bed comprising an alkali metal, e.g., sodium, and ammonium or amine salts of a strong acid cation exchange resin by contacting the cation resin with an aqueous solution of an alkaline earth metal hydroxide, e.g., calcium hydroxide, thereby exchanging the alkali metal and ammonium or amine cations with alkaline earth metal cations. The aqueous liquid containing the alkali metal and ammonia or amine is subsequently passed through a cation exchange resin which removes the alkali metal from the liquid. The recovery of ammonia or the amine by such method is particularly useful in condensate purification system associated with a power production facility wherein the recovered ammonia or amine can be employed to reduce corrosion in the power production facility and the strong acid resin, upon regeneration, can be used to remove alkali metal ions, particularly sodium, from the facility.

Abstract: This invention relates to compounds having the formula ##STR1## in which R.sub.F is a perfluoro radical C.sub.n F.sub.2n+1 with n=1-20, and R is a C.sub.1-20 alkyl radical, a C.sub.4-15 cycloalkyl radical, a C.sub.5-20 cycloalkyl-alkyl radical, or a C.sub.6-20 aromatic radical.Said compounds constitute valuable intermediates for the synthesis of surface-active agents.

Abstract: Amines are N-alkylated by reaction with an alcohol or a carbonyl compound in the presence of hydrogen under atmospheric pressure in the gas phase over a catalyst, containing copper and aluminum, which is obtained by heating and reducing a basic precipitate of salts of copper and aluminum.
