Problems solved by technology

[0003] At present, the reaction waste liquid of ethylene copolymerization to produce α-olefins includes both organic matter and cadmium catalyst. At present, the waste liquid treatment method is mainly to pour it into the waste liquid recovery bin together with other organic waste liquids, and mix it with other organic reaction waste liquids and hand it over to the waste liquid. The processing organization conducts unified processing, which is costly and the reactants cannot be recycled
So far, there is no purification treatment agent and treatment method specially designed for this organic reaction, so it is of great significance to design a special purification treatment agent and treatment method for the reaction of ethylene copolymerization to produce α-olefins

Embodiment 1

[0044] A kind of purification treatment agent of organic reaction waste liquid, described purification treatment agent is made through the following steps:

[0045] (1) Sodiumization of montmorillonite, put 1kg montmorillonite into 2.5L distilled water, mechanically stir for 1h, then slowly add 0.36kg sodium hexametaphosphate therein, mix uniformly to obtain sodium montmorillonite solution;

[0046] (2) Get 425g ferric chloride hexahydrate and 305g ferrous chloride tetrahydrate, place in 2.5L distilled water, then heat to 35-45 degrees centigrade and stir evenly to obtain molten iron;

[0047] (3) Take 10 g of cationic starch and add it to 25 ml of deionized water, and use high-pressure homogenization for 3-4 hours to obtain a cationic complex liquid; wherein the molecular weight of the cationic starch is 500,000 to 2,000,000 g / mol; the degree of substitution is 0.5-1; the charge density 3-6meq / g.

[0048](4) Slowly add the iron obtained in step (2) to the sodium montmorillon...

Abstract

The invention discloses a purifying treating agent for an organic reaction waste liquor and a treating method. The purifying treating agent is prepared by modifying montmorillonite with a ferric saltand cation modified natural polymer. The purifying treating agent has excellent absorbing property and purifying property. The cost of organic reaction can be greatly reduced by treating the organic reaction waste liquor according to the method.

Description

technical field [0001] The invention belongs to the field of waste liquid treatment, and in particular relates to a purification treatment agent and a treatment method for organic reaction waste liquid. Background technique [0002] Linear α-olefins are an important class of chemical raw materials, mainly used to prepare plasticizers, lubricants, surfactants, epoxy compounds, etc. Among them, 1-hexene and 1-octene are synthetic linear low-density polyethylene ( LLDPE) is an important comonomer. In recent years, many important advances have been made in the research of ethylene selective oligomerization technology. At present, among the ethylene selective oligomerization catalysts, titanium-based, tantalum-based, chromium-based and other catalysts have shown good catalytic performance, among which Cr-based catalysts have superior comprehensive performance (high conversion rate and high selectivity). At present, more and more researchers are studying the catalytic performanc...
