Abstract: The present invention relates to a catalyst for dehydration of a primary alcohol, a method of preparing the same, and a method of producing an alpha-olefin using the same. The catalyst for dehydration of a primary alcohol according to the present invention has an excellent catalyst stability while having an excellent activity with respect to dehydration, and a high turnover frequency, such that a linear alpha-olefin with high purity may be produced with a high selectivity even in a case where a relatively small amount of a cocatalyst is added as compared with a homogeneous catalyst system.

Abstract: An automated liquid sample device is disclosed. The automated liquid sampling device of the present invention comprises: a first pipe which is connected to a (1-2)th inlet-side flow channel of a first three-way valve and through which a gas is exhausted to the outside; a second three-way valve which forms a (2-1)th inlet, a (2-2)th inlet, and a (2-3)th inlet, has a (2-1th inlet-side flow channel connected to a (1-3)th inlet-side flow channel of the first three-way valve, and has a (2-2)th inlet-side flow channel connected to a second trap, a third three-way valve which forms a (3-1)th inlet, a (3-2)th inlet, and a (3-3)th inlet; a second pipe which connects a (3-1)th inlet-side flow channel to a (2-3)th inlet-side flow channel; a third pipe which connects a (3-2)th inlet-side flow channel to the (1-2)th inlet-side flow channel of the first three-way valve; a fourth pipe which connects a (3-3)th inlet-side flow channel to the first pipe; and a controller which controls the first valve, the first three-way valve, the second three-way valve, and the third three-way valve.
