A process for producing a carbamate is disclosed. In one embodiment, the process comprises contacting a mixture comprising a primary amine component, an urea component and a hydroxy nitrogen component, in particular at least one oxime, at conditions effective to form a carbamate. Certain novel carbamates are also disclosed.

Process for producing carbamates from oximes

A method is disclosed for separating alkyleneamines from a mixture of by-product alkali or alkaline earth metal chloride salt and alkyleneamines comprising the sequenced combination of the steps of: (a) washing said amine-chloride salt mixture with an aqueous alkali or alkaline earth metal hydroxide solution to form a washed amine-chloride salt mixture; and (b) treating a mixture of the amino and chloride salt to physically separate chloride salt from said amine of said mixture.

Recovery of amines from by-product chloride salts

The present invention concerns a potentiated nickel catalyst and its use for the catalytic amination of lower aliphatic alkane derivatives.

Potentiated nickel catalysts for amination

The present invention concerns a new nickel-rhenium catalyst and method of preparing said catalyst. The invention also relates to the catalytic amination of lower aliphatic alkane derivatives such as alkanemono-ols, alkanediols and alcoholamines utilizing the new nickel-rhenium catalyst.
