PROBLEM TO BE SOLVED: To provide a new catalyst for dehydration reaction that is further improved in activity and the at a high level in mechanical strength in a vapor dehydration reaction such as vapor phase etherification and vapor phase esterification, and to provide a method capable of producing 2-valent phenol monoalkyl ether at a high conversion and high selectivity in the vapor phase dehydration reaction of 2-valent phenol and lower alcohol. SOLUTION: The catalyst for dehydration reaction consists of aluminum, phosphorus, titanium, silicon, antimony of bismuth and oxygen having the atomic ratios of phosphorus of 1.0-1.9 atoms, titanium of 0.05-0.5 atoms, silicon of 0.05-0.2 atoms, antimony or bismuth of 0.01-0.3 atoms and oxygen of 4.2-8.4 atoms per aluminum of 1 atomic ratio and 2-valent phenol and lower alcohol are dehydrated in a gas phase and in the presence of the catalyst. |
