Embodiment 1

[0025] Weigh 0.4g of ferric nitrate nonahydrate, 0.3g of sodium dihydrogen phosphate and 2.0g of polyvinylpyrrolidone (Mw=3000000) into 100ml of 50% ethanol aqueous solution, after ultrasonic dispersion at a temperature of 25°C and a stirring speed of 320r / min Stir at constant temperature for 60 min to form a uniform mixed solution. Put the solution into a hydrothermal kettle and react at 180°C for 10 h. After natural cooling, remove the supernatant and wash twice with deionized water and ethanol to obtain FePO 4 2H 2 O. Dry in a vacuum oven at 80°C for 7h, and then bake at 550°C in a muffle furnace for 2h to obtain dendritic iron phosphate FePO 4 .

Embodiment 2

[0027] Weigh 0.5g of ferric nitrate nonahydrate, 0.4g of sodium dihydrogen phosphate and 2.0g of polyethylene glycol (Mw=20000) into 150ml of 50% ethanol aqueous solution, after ultrasonic dispersion at a temperature of 25°C and a stirring speed of 400r / min Stir at constant temperature for 60 min to form a uniform mixed solution. Put the solution into a hydrothermal kettle and react at 100°C for 16 hours. After natural cooling, remove the supernatant and wash twice with deionized water and ethanol to obtain FePO 4 2H 2 O. After drying in a vacuum oven at 50°C for 5h, and then roasting in a muffle furnace at 500°C for 2h, dendritic iron phosphate FePO 4 .

Embodiment 3

[0029] Weigh 0.8g of ferric nitrate nonahydrate, 0.3g of sodium dihydrogen phosphate and 2.0g of polyvinylpyrrolidone (Mw=3000000) into 100ml of 50% ethanol aqueous solution, and ultrasonically disperse them at a temperature of 25°C and a stirring speed of 300r / min. Stir at constant temperature for 60 min to form a uniform mixed solution. Put the solution into a hydrothermal kettle and react at 150°C for 12 hours. After natural cooling, remove the supernatant and wash twice with deionized water and ethanol to obtain FePO 4 2H 2 O. After drying in a vacuum oven at 60°C for 10h, it was then fired in a muffle furnace at 520°C for 2h to obtain flower-shaped iron phosphate FePO 4 .

Abstract

The invention discloses a preparation method of different morphologies of micron-level ferric phosphate and application thereof. The preparation method comprises the steps that iron nitrate nonahydrate, sodium dihydrogen phosphate and a surface active agent are put in an ethanol water solution, ultrasonic dispersion is performed to obtain uniform mixed solution, reaction is performed at the temperature of 100-200 DEG C, and calcination is performed at the temperature of 400-650 DEG C to obtain the micron-level ferric phosphate. According to the preparation method, different morphologies of micron-level ferric phosphate are directionally prepared by adjusting the putting ratio of the iron nitrate nonahydrate to the sodium dihydrogen phosphate under the conditions of different reaction temperatures and times. The prepared different morphologies of micron-level ferric phosphate have higher methylcellulose catalysis performance, and a new method is provided for preparation of 5-hydroxymethyl furfural.

Description

technical field [0001] The invention belongs to the field of catalyst preparation and application, and in particular relates to a preparation method of micron iron phosphate with different shapes and its application in catalytic preparation of 5-hydroxymethylfurfural. Background technique [0002] 5-Hydroxymethylfurfural is an active ingredient that widely exists in traditional Chinese medicine (such as angelica, etc.), and has good effects in treating leukemia, endotoxemia, anti-oxidation and lowering blood pressure. 5-Hydroxymethylfurfural is mostly produced by dehydration of fructose and glucose as raw materials under acid-catalyzed conditions. However, this process has low yield, high energy consumption and high cost, thus limiting the production and application of 5-hydroxymethylfurfural. [0003] On the one hand, the present invention provides a new method for preparing 5-hydroxymethylfurfural by using methyl cellulose, iron phosphate and tetrahydrofuran as raw materi...
