Problems solved by technology

At present, the content of 1-decene in the by-product decene in the 1-hexene industrial plant is relatively low, and there is no suitable and simple separation technology at present, and it is difficult to obtain high-purity 1-decene
The above-mentioned oligomerization catalyst system is not suitable for the oligomerization of mixed decenes, the oligomerization effect is poor, and the conversion rate is low
The oligomerization reaction of mixed decenes is rarely reported

Embodiment 1

[0023] Preparation of Catalyst A:

[0024] Weigh 10g of silicon dioxide and sinter at 700°C for 15 hours, then cool down to 200°C, and put it in a vacuum drying oven for later use. Under nitrogen protection, add above-mentioned processed silicon dioxide and 50ml n-hexane into the polymerization bottle, add 4g of sesquiethylaluminum chloride with a mass concentration of 25% in the polymerization bottle with a syringe, stir at room temperature for 1 hour, and use After washing with n-hexane, the obtained solid was vacuum-dried for 10 hours to obtain supported catalyst A.

Embodiment 2

[0026] Preparation of Catalyst B:

[0027] The operation method is the same as that of Example 1, except that the silica carrier is replaced by aluminum oxide to obtain supported catalyst B.

Embodiment 3

[0029] Preparation of Catalyst C

[0030] The operation method is the same as in Example 1, except that the sesquiethylaluminum chloride is replaced by 4 g of ethylaluminum dichloride to obtain supported catalyst C.

Abstract

The invention provides a mixed decene oligomerization catalyst, which is a two-component catalyst system containing a load type organic aluminum compound and a proton donor as an acceleratant. In the two-component catalyst system, the proton donor and the aluminum atom in the load type organic aluminum compound are in a mole ratio of 0.2:1-1:1. The two-component catalyst system can be used as a mixed decene oligomerization catalyst to make a mixed decene by-product in 1-hexene industrial equipment undergo oligomerization directly, thus obtaining an oligomer, wherein the conversion rate of the mixed decene is greater than 50%. By means of the catalyst provided in the invention, the raw material utilization rate can be enhanced, the input cost can be reduced, and the economic benefits can be increased.

Description

technical field [0001] The invention relates to a mixed decene oligomerization catalyst, in particular to a catalyst for mixed decene by-products in 1-hexene industrial production devices. The catalytic system of the present invention can effectively catalyze the oligomerization of mixed decenes, so that by-products in 1-hexene industrial devices can be reused. Background technique [0002] The oligomer of decene has high viscosity, high viscosity index, low pour point, wide temperature range, good thermal stability, low corrosion, good miscibility with mineral lubricating oil, good compatibility with common materials and non-toxic And other characteristics, it is a very good lubricating oil base oil, mainly used in the automobile and shipbuilding industries. There are many studies on decene oligomerization, and the catalyst system has BF 3 system, Cr system, Al compound system and Ziegler-Natta system, etc. Such as US Patent Application Publication US4365105 adopts BF 3...
