| 摘要 | PURPOSE: To continuously and stably produce azine by reacting hydrogen peroxide, ammonia and a compd. having a carbonyl group while bringing them into contact with a circulating operation liquid and subsequently successively separating azine and reaction water from the circulating operation liquid. CONSTITUTION: In a reaction apparatus 20, hydrogen peroxide 3, ammonia 4 and a compd. having a carbonyl group (e.g.; acetone, methyl ethyl ketone) 1 are brought into contact with an operation liquid 5 to be reacted at 30-70°C. Azine and an excessive amt. of the compd. having the carbonyl group are separated from the operation liquid and azine is hydrolyzed 60 to obtain hydrolyzed hydrazine 8 and the reaction product and an excessive amt. of the compd. having the carbonyl group recovered after hydrolysis are circulated 1 to the reaction apparatus 20. The operation liquid 9 is sent to a tower 40 and reaction water and a small amt. of ammonia are removed 10 and a tower bottom component is sent to an ion exchange resin absorbing apparatus 50 to remove heavy impurities to be circulated to the reaction apparatus 20. The operation liquid is prepared by forming org. or inorg. oxygen acid, its ammonium salt or its deriv. into a soln. COPYRIGHT: (C)1990,JPO |
