Embodiment 1

[0053] Example 1: Synthesis of DNL-6 molecular sieve catalyst

[0054] Initial gel Moore composition ratio 2N-methylbutylmine (as an organic structural guide): 0.3 Sio 2 : 0.4P 2 O 5 : 0.5al 2 O 3 : 50h: 50h 2 O: 0.2 (20%) of hexadalkyltrimel bromide (as seed) will meter the organic structural guide, silica sol, phosphoric acid, isopropanol, deionized water, and seed crystals in a beaker The gel is fully stirred, and then loaded into the stainless steel autoclave of the inner lining polytetrafluoroethylene, at a constant temperature of 200 ° C, a rotational crystal crystallization of 75 R / min. After crystallization, the centrifuge 3000 rp / separated center was 3 min, and the obtained solid product was washed with deionized water, and after drying overnight at 120 ° C, XRD analysis results figure 1 Indicated. As can be seen from the results of Fig. 1, the synthetic product is a DNL-6 molecular sieve powder, which is calcined at 550 ° C for 5 h to obtain a DNL-6 molecular sieve, ...

Embodiment 2

[0055] Example 2: Synthesis of SAPO-42 molecular sieve catalyst

[0056] Proportion of 1.85 2,2-dimethyl-2,3-dihydro-1H-phenyl group [DE] isoquinoline (as an organic structural guide): 0.296sio 2 : 0.85P 2 O 5 : 1Al 2 O 3 : 60h 2 O The metered organic structural guides, silica sol, phosphoric acid, and thin aluminum stone and deionized water are mixed in the beaker, stir well, then loaded into the stainless steel autoclave of the inner lining polytetrafluoroethylene, 175 ° C constant temperature crystallization 120h. After crystallization, 3 min 300 rutthest centrifuge was crystallized, and the obtained solid product was washed with deionized water, and the XRD analysis results after drying overnight in air at 100 ° C. figure 2 Indicated. From figure 2 As a result, it can be seen that the synthetic product is SAPO-42 molecular sieve powder powder, which is calcined at 600 ° C for 5 h to obtain SAPO-42 molecular sieve, which is recorded as a catalyst 2.

Embodiment 3

[0057] Example 3: Synthesis of ZK-21 molecular sieve catalyst

[0058] 6.1 g of aluminate (1.11NA) 2 O · Al 2 O 3 · 3.5H 2 O) mixed with a small amount of deionized water, adding 23 g of concentration of 85% phosphoric acid, an aqueous solution of aqueous solution, and 10.3 g of sodium biased silicate five hydrate and 80 ml of deionized water, and thoroughly agitated, then gave obtained The stainless steel autoclave loaded into the lined polytetrafluoroethylene was 100 ° C. After crystallization, 3 min 300 rutthest centrifuge was crystallized, and the obtained solid product was washed with deionized water, and the XRD analysis results after drying overnight in air at 100 ° C. image 3 Indicated. From image 3 As a result, it can be seen that the synthetic product is a ZK-21 molecular sieve powder, which is calcined at 600 ° C for 5 h, and it is obtained to obtain a ZK-21 molecular sieve, which is recorded as a catalyst 3.

Abstract

The application discloses a method for preparing coronene compounds, the method comprising the following steps: (1) pre-treating a catalyst containing SAPO molecular sieves; (2) loading a raw material containing acyclic olefins into a reactor , contacting and reacting with the pretreated catalyst in step (1), to obtain the coronene compound; wherein, the pretreatment is to activate the catalyst. The method does not require expensive raw materials, complicated operations, and is suitable for large-scale production.

Description

Technical field [0001] The present application relates to a method of preparing a teenzocene compound by non-annular olefin, belonging to an organic chemistry. Background technique [0002] Because of the use of fluorescent materials, chizzle and their derivatives have been focused on people. In recent years, people have found that chizzle and its derivatives are excellent organic fluorescent materials for making UV-CCDs. The maximum emitting wavelength of the chizzain is 520 nm, and the maximum absorption wavelength is 255 nm while also has high quantum efficiency. Holly is a very ideal UV-CCD material. [0003] At present, the preparation method for chizzain is mainly including the following three: [0004] The first method is the preparation method disclosed in J.org.Chem. 1596, 61, 1136-1139, which is as follows: [0005] [0006] In this method, it is necessary to cool down to -60 ° C, it is not easy to operate, and the reaction step is more and the operation is cumbersome...
