Embodiment 1

[0041] 0.1 mol N-methylimidazole water bath was heated and magnetically stirred. When the temperature reached 80 ° C, 0.1 mol bromo-n-butane was slowly added dropwise. After the dropwise addition, the temperature was controlled at 85 ° C and stirred to completely reacted to obtain a golden yellow, transparent, viscous liquid. After the reaction was completed, it was cooled to 50 ° C, and the excess reaction raw material was extracted multiple times with ethyl acetate, and the residual acetate was evaporated.

[0042] The resulting bromine N-methylimidazole ionic liquid is further obtained by affecting phosphotungstic acid: quantifying 12 mmol bromo-methylimidazole ion liquid, weighing 3 mmol phosphate hydrochloric acid completely dissolved in deionized water The phosphorsticic acid solution is slowly added dropwise while stirring, and white precipitation is gradually occurs. After the dropwise addition, it refused to return at 60 ° C for 8 h. After the end of the reaction, the dis...

Abstract

The invention discloses a heteropolyacid ionic liquid-loaded aminated magnetic composite material with jujube cake type structure, a preparation method and an application thereof. The raw materials for preparing the composite material include a heteropolyacid ionic liquid and an aminated magnetic composite material. The multi-acid ionic liquid is supported on the aminated nano-magnetic material to obtain a composite material. The preparation steps are as follows: firstly adopt substitution reaction to prepare heteropolyacid ionic liquid, solvothermal method to prepare aminated magnetic composite material, and then adopt ultrasonic loading method to prepare heteropolyacid ionic liquid supported aminated magnetic composite material. The product obtained by the method of the invention is powdery, brown in color, uniform in particle size distribution, jujube cake-shaped structure and stable in property. It overcomes the shortcomings of easy agglomeration of magnetic materials, and the obtained materials have good dispersibility, high magnetic properties, easy access to raw materials, and high yield; both magnetic and catalytic activities can be effectively used as catalysts for desulfurization of petroleum samples, and the catalysts can be separated and recycled. .

Description

Technical field [0001] The present invention relates to hetero structure A fruit cake ionic liquid supported heteropolyacid magnetic composites amination, preparation method and application technique, particularly for the liquid and a heteropolyacid ion amination magnetic composite material and its preparation date cake structure preparation of acid ionic liquid load aminated magnetic composite materials, and the use of date cake type according to the present invention, the structure of a heteropolyacid ion liquid load aminated magnetic composites as a catalyst, hydrogen peroxide as the oxidant catalytic petroleum sample desulfurization achieve petrochemical deep desulfurization and other purposes. Background technique [0002] With the progress and development of technology, oil plays an important role in promoting the process of industrialization. But oil to sulfur present in the form of hydrogen sulfide, thiophene, disulfide oil not only affects the quality of combustion gener...
