preparation example Construction

[0030] Preparation of β-FeOOH particles of the present invention:

[0031] (1) Weigh 0.3g of anhydrous ferric chloride and 10mL of absolute ethanol into a 40mL autoclave, slowly add 20mL of distilled water into the autoclave under constant stirring, then seal the autoclave, heat up to 80°C and keep for 72 Hour;

[0032] (2) The autoclave was naturally cooled to room temperature, the precipitate was collected, washed three times with distilled water, and then dried in air at 60° C. for 3 hours to obtain β-FeOOH particles.

[0033] Characterization of β-FeOOH particles: measured by X-ray diffractometer, field emission scanning electron microscope, Fourier transform infrared spectrometer, X-ray photoelectron spectrum, differential thermal analyzer, fully automatic specific surface and porosity analyzer, the measurement results are shown in Figure 1 to Figure 7 shown.

[0034] figure 1 It is the XRD diffraction pattern of β-FeOOH particles, and all the diffraction peak indicat...

Embodiment 1

[0044] The β-FeOOH particles prepared in Example 1.

[0045]Put the β-FeOOH particle sample prepared in Example 1 into a mortar and grind it into powder, weigh 14g of the ground β-FeOOH powder, put it into a 500mL Erlenmeyer flask, add 280mL of water, and ultrasonically disperse it fully , to obtain 50g / L of β-FeOOH solution, marked as solution I.

Abstract

The invention discloses beta-FeOOH particles, a preparation method and application thereof. The beta-FeOOH particles have spindle-shape microstructure and are prepared by the following method: (1) adding ferric chloride and ethanol to an autoclave, slowly adding water while stirring, sealing the autoclave after adding is finished, raising temperature to between 78 and 82 DEG C and keeping for 71 to 73 hours; and (2) cooling the autoclave to room temperature, washing and drying obtained precipitates and obtaining finished products. When the beta-FeOOH particles are used as cigarette additives, the beta-FeOOH particles can effectively reduce the nitrosamine content of cigarette smoke, are dissolved in water and then added to cut tobacco in a spraying way, use no toxic reagents, do not affect the appearance and taste of cigarettes, and do not affect the burning of the cigarettes or conventional composition of cut cigarette.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a β-FeOOH particle, and also to a preparation method and application of the β-FeOOH particle. Background technique [0002] Nitrosamines (TSNAs) in cigarette smoke are formed by the action of secondary amines and nitrous acid or nitrogen oxides in the process of tobacco burning. They are a strong cancer-inducing agent unique to tobacco. This is because nitrosamines Contains -N-N=O groups, has electrophilic properties, directly acts on DNA, and causes blood ring genes to mutate. At present, N-nitroso nornicotine (NNN), 4-(N-methylnitrosamine)-1-(3-pyridyl)-1-butanone (NNK), N-nitroso N-nitroso anatabine (NAB) and N-nitroso anatabine (NAT) have been studied more deeply. [0003] With the improvement of living standards, people pay more and more attention to health, and the research on reducing harmful components in cigarette smoke has also attracted more and more attention. my country has...
