Problems solved by technology

[0002] Light aliphatic hydrocarbons are widely used in petrochemical and other fields, but they are very difficult to separate due to their similar molecular size, molecular weight and boiling point
The traditional process is to use low-temperature distillation, but this method needs to be realized at a lower temperature and high pressure, which wastes a lot of cost

Embodiment 1

[0012] Example 1: Porous indium-organic framework material A

[0013] At room temperature, 0.1 mmol of 4,4',4''-(1,3,5-triazine)-2,4,6-tribenzoic acid, 0.075 mmol of indium nitrate hydrate and 0.075 mmol of tetraethyl chloride Ammonium was added to 10ml N,N'-diethylformamide solution, and the temperature was gradually raised to 100°C. After 24 hours of reaction, the temperature was lowered to room temperature, filtered, washed with N,N'-diethylformamide, ethanol , washed with dichloromethane, and dried in vacuum to obtain a porous indium-organic framework material A.

Embodiment 2

[0014] Example 2: Porous indium-organic framework material A

[0015] At room temperature, 2 mol of 4,4',4''-(1,3,5-triazine-2,4,6-)tribenzoic acid, 1.5 mol of indium nitrate hydrate and 1.5 mol of tetraethylammonium chloride , added to 1L N,N'-diethylformamide solution, gradually raised the temperature to 150°C, reacted for 72 hours, lowered to room temperature, filtered, washed with N,N'-diethylformamide, ethanol, Wash with dichloromethane and dry in vacuum to obtain porous indium-organic framework material A.

Embodiment 3

[0016] Example 3: Porous indium-organic framework material A

[0017] At room temperature, 0.1 mmol 4,4',4''-(1,3,5-triazine)-2,4,6-tribenzoic acid, 0.075 mmol indium chloride and 0.075 mmol tetraethylammonium chloride , added to 10ml of N,N'-diethylformamide solution, gradually raised to 130°C, reacted for 48 hours, cooled to room temperature, filtered, washed with N,N'-diethylformamide, ethanol, Wash with dichloromethane and dry in vacuum to obtain porous indium-organic framework material A.

Abstract

The invention relates to a method for preparing a porous indium-organic framework material based on 4,4',4''-(1,3,5-triazine)-2,4,6-tribenzoic acid serving as a ligand and application thereof in the adsorption and separation of light aliphatic hydrocarbons. The porous indium-organic framework material is prepared from 4,4',4''-(1,3,5-triazine)-2,4,6-tribenzoic acid ions, indium ions and tetraethylammonium ions by a solvothermal method. The material is simple in preparation, has relatively high adsorption capacity to the light aliphatic hydrocarbons (such as methane, ethene, ethyne, ethane and propane) under the conditions of room temperature and normal pressure, and has very high selective separation performance on methane, ethene, ethyne, ethane and propane.

Description

technical field [0001] The invention belongs to the technical field of gas adsorption and separation, and in particular relates to a preparation method of a metal indium-based porous metal-organic framework material and an application of adsorbed gas. Background technique [0002] Light aliphatic hydrocarbons are widely used in petrochemical and other fields, but they are very difficult to separate due to their similar molecular size, molecular weight and boiling point. The traditional process is the method of cryogenic distillation, but this method needs to be realized at a lower temperature and high pressure, which wastes a lot of cost. However, the method of adsorption separation can be realized at lower pressure and higher temperature, which saves costs. Contents of the invention [0003] The object of the present invention is to propose a porous metal-organic compound formed by reacting 4,4',4''-(1,3,5-triazine)-2,4,6-tribenzoic acid with indium salt as a ligand Pre...
