Paragraph 0034-0035, (2017/07/05)
The invention discloses a method for preparing dibutoxymethane, and relates to a method for preparing methane. The method comprises the following processes: dimethoxymethane and n-butanol are adopted as raw materials, and molecular sieves adopting different topological structures are adopted as catalysts for preparing dibutoxymethane at a temperature under the pressure; the atomic ratio of silicon to aluminum in the catalysts, namely, the molecular sieves adopting the different topological structures is as follows: Si/Al=3-100; the molecular sieves adopting the different topological structures are one or more of an H-type MCM-22 molecular sieve, an H-type ZSM-35 molecular sieve, an H-type ZSM-5 molecular sieve, H-mordenite, H-zeolite Y and an H-type Beta molecular sieve; structure types of the catalysts, namely, the molecular sieves adopting the different topological structures are selected from at least one of MWW, FER, MFI, MOR, FAU and BEA. According to the method, relatively single products are produced, the selectivity is high, required raw materials are cheap and easy to obtain, and the whole process is easy to operate; meanwhile, no chemical substances polluting the environment are produced, and the method belongs to an environment-friendly technological path.
