摘要:
This invention relates to an improvement in the vapor phase catalytic production of an amine by the reaction of a mixture comprising a C 2-4 olefin and ammonia. The improvement which provides for high conversion and selectivity to the amine resides in the use of an acidic offretite as the catalyst.

The invention relates to alkylated diamine compounds having the formula where R 1 , R 2 , R 3 and R 4 , which may be the same or different, are selected from hydrogen and from alkyl groups containing from 8 to 30 carbon atoms with the proviso that at least one of R 1 , R 2 , R 3 and R 4 is not hydrogen, and where p is an integer in the range 2 to 12. In preferred embodiments one or more of R 1 , R 2 , R 3 and R 4 are long chain alkyl groups containing 13 or 15 carbon atoms, the amount of branching being in the range 30 to 70%, and the integer p is 6. The alkylated diamine compounds are conveniently prepared by reaction of one or more aldehydes R.CHO where R is R 1 , R 2 , R 3 and or R 4 with an α,w diamine and the compounds may be used for example as bitumen adhesion agents.
摘要:
A process for the production of symmetrical and unsymmetrical substituted diarylamines is disclosed. The process provides said diarylamines in high yield and purity by the reaction of a salt of an arylsulfonic acid and an alkali metal salt of a primary arylamine in the presence of an inorganic alkali metal salt. Curve B was obtained by a process in accordance with the invention, and curve A was obtained by a corresponding prior art procedure in which the inorganic alkali metai salt was omitted.
