<p>Disclosed is a method of preparing amines of general formula (I), in which R?1, R2, R3, R4, R5 and R6¿ are hydrogen, C¿1?-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C3-C20 cycloalkyl, C4-C20 alkylcycloalkyl, C4-C20 cycloalkylalkyl, aryl, C7-C20 alkylaryl or C7-C20 aralkyl, R?1 and R2¿ together form a saturated or unsaturated C¿3?-C9 alkylene di-chain and R?3 or R5¿ is C¿21?-C200 alkyl or C21-C200 alkenyl or R?3 and R5¿ together form a C¿2?-C12 alkylene di-chain, by reacting olefins of general formula (II), in which R?3, R4, R5 and R6¿ are as defined above, with ammonia or primary or secondary amines of general formula (III), in which R?1 and R2¿ are as defined above, at temperatures of 200 to 350 °C and pressures of 100 to 300 bar in the presence of a zeolite catalyst, a boron β-zeolite being used as the catalyst.</p> |
