The present invention relates to a novel process for the preparation of phenyl ethyl amine derivatives by reacting a phenyl ethyl hydroxy compound with hydrogen cyanide followed by in situ hydrolysis.

Disclosed is a method for efficiently synthesizing primary amines, which comprises using carbonyl compounds or alcohol compounds as reaction substrate, liquid ammonia or alcohol solutions of ammonia as nitrogen source, and hydrogen as hydrogen source, and reacting in reaction medium catalyzed by a cobalt-based catalyst to obtain the primary amines. Due to high catalytic activity, the method can realize the reductive amination of carbonyl compounds and the hydrogen-borrowing amination of alcohol compounds at low temperatures in a short time to obtain the primary amines with high yield, and is applicable to a wide range of substrates. The obtained primary amines can be used as raw materials with high extra value for producing polymers, medicines, dyes and surfactants. Further, the cobalt-based catalyst has a good industrial application prospect because it is magnetic which can facilitate separation and recycling of the catalyst. Moreover, the inexpensive cobalt-based catalyst can significantly reduce industrialization cost.

Uses are disclosed for a new crystalline molecular sieve designated SSZ-102 synthesized using an N,N′-dimethyl-1,4-diazabicyclo[2.2.2]octane dication as a structure directing agent. SSZ-102 has ESV framework topology.

The present invention relates to a process for purifying ethylenediamine (EDA) by distillation, wherein the process comprises the steps a) and b). In step a), a mixture (G1) comprising water, EDA and N-methylethylenediamine (N-MeEDA) is fed into a distillation apparatus (D1), and the major part of the water comprised in the mixture (G1) is separated off overhead at a pressure of greater than 4.8 bara. From the bottom of (D1), the water-enriched mixture (G2) is fed into a distillation apparatus (D2) in step b). At the top of (D2), the major part of the N-MeEDA is distilled off. The stream (S3) obtained from the bottom of (D2) comprises EDA, with the components water and N-MeEDA comprised in the mixture (G1) having been largely or completely removed. Further distillation steps can optionally be carried out in order to obtain pure EDA, for example when diethylenetriamine (DETA) is additionally comprised in the mixture (G1). If ammonia is additionally comprised in the mixture (G1), an ammonia removal is preferably additionally carried out before carrying out the step a) in the process of the invention.
