Abstract

The invention relates to a method for producing nitroalkane and co-producing ketoxime. The method comprises the following steps: in the presence of a molecular sieve catalyst of ketone ammoxidation, taking ketone, ammonia and hydrogen peroxide as reaction raw materials to generate nitroalkane and co-generate ketoxime. The method disclosed by the invention is mild in reaction conditions, safe and environment-friendly, simple in separation and high in the purity of the product, and the yield of the nitroalkane in the product can be adjusted, so as to obtain the ratio of the required nitroalkaneto ketoxime, so that the method for producing nitroalkane and co-producing ketoxime enhances the production elasticity of the nitroalkane, and the economic benefits of the whole process are improved.

Description

technical field

[0001] This application relates to a method for producing nitroalkanes and co-producing ketoxime, in particular to a method for producing nitroalkanes and co-producing ketoxime by using a specific catalyst and using ketone, ammonia and hydrogen peroxide as raw materials . Background technique

[0002] Nitroalkane is an important fine chemical raw material, such as 2-nitropropane can be used to produce 2-amino-2-methylisopropanol and so on. At present, the production method of this nitroalkane all adopts the nitration method of alkane (as disclosed in the Chinese patent application CN201080047327.4), and the Chinese patent application CN201010592408.4 has also carried out certain improvements in the reactor and other aspects. However, in these methods, there are still problems of dangerous operation, serious pollution and low selectivity of target products.

[0003] Ketoxime, such as acetone oxime, as a low toxicity, efficient reducing agent, has not only be...
