Abstract
Modification phosphate aluminium molecular sieve material the invention discloses hydrocyanic acid release amount in a kind of energy selectivity reducing cigarette main flume and preparation method and application.By adding triethylamine template, using chromic nitrate as chromium source, boehmite is silicon source, and phosphoric acid is phosphorus source, and CrAPO 5 is synthesized using hydro-thermal method.The material first Application is in cigarette filter rod, and alternative reduces the hydrocyanic acid release amount 53.29% in cigarette mainstream flue gas, to the reduced rate unobvious of other gas burst sizes in cigarette mainstream flue gas.Compared on going result, additive amount is few, can realize efficiently drop evil, have good application value.
Description
Technical field
The present invention relates to a kind of modified phosphate aluminum molecular screen materials and preparation method and application, and in particular to a kind of to select
Selecting property reduces modified phosphate aluminum molecular screen material of determination of hydrogen cyanide in mainstream cigarette smoke burst size and preparation method and application, belongs to
In cigarette material preparing technical field.
Background technology
As people are to the growing interest smoked with health problem, the harmful components in cigarette, the suction for improving cigarette are reduced
Eating safety becomes the emphasis of tobacco business research work.Domestic tobacco business has carried out into one the substance in Huffman inventory
Step is clear and definite, and State Bureau points out CO, HCN, NNK, NH3, 7 kinds of benzo [a] pyrene, phenol and crotonaldehyde harmful components burst sizes can be effective
Characterize cigarette mainstream flue gas biohazardous.For further Development of Tobacco, the volume of low tar, less harmful is researched and developed
Cigarette is the top priority of current enterprise.
Hydrogen cyanide(HCN)It is a kind of colourless poisonous gas or liquid with semen armeniacae amarae taste, low boiling point, volatile, room temperature
Under exist in gaseous form, can by all means it is oral or nasal sucking make one to be poisoned, hydrogen cyanide is soluble easily in water, ethyl alcohol, micro-
Ether is dissolved in, aqueous is in faintly acid, belongs to the extremely toxic substance of high volatile, and intoxication mainly passes through CN-Occur.Hydrogen in cigarette
Cyanic acid is mainly derived from nitrate and nitrogenous compound in tobacco(Such as amino acid, protein)Oxidation point during burning and sucking
Solution, burst size are about 30-300 μ g/ branch, and the hydrogen cyanide in flue gas is sucked through respiratory tract, can be with internal high swage cell color
Plain oxidizing ferment, which combines, becomes cyaniding high ferro shape cytochrome oxidase, loses the effect for transmitting oxygen, causes histanoxia and be poisoned,
Harm is generated to the health of people.Therefore, exploitation can effectively reduce the material of determination of hydrogen cyanide in mainstream cigarette smoke burst size
To improving smoking property of cigarette safety, protection human health is of great significance.
At present, the removal for hydrogen cyanide micro in cigarette mainstream flue gas both at home and abroad, it is more using absorption method and catalysis oxygen
Change method.Ammonium carboxylate salt made from the primary amine or secondary amine of alkyl or hydroxyalkyl and carboxylic acid reaction is dispersed in by US3410282 can make cigarette
Gas by carrier on, the HCN in selectively removing cigarette smoke.CN1462652A etc. elaborates that catalytic oxidation is reducing volume
Effect in cigarette in hydrogen cyanide shows higher catalytic activity.But production cost is higher, and in process of production, meeting
Have and be unevenly distributed phenomenon in single cigarette, it is difficult to control.
Invention content
In view of the defects existing in the prior art, the present invention provides hydrogen cyanide in a kind of energy selectivity reducing cigarette main flume
Modified phosphate aluminum molecular screen material of burst size and preparation method and application.
The purpose of the present invention is achieved through the following technical solutions:
The preparation side of the modified phosphate aluminum molecular screen material of hydrocyanic acid release amount in a kind of energy selectivity reducing cigarette main flume
Method includes the following steps:
(1)The preparation of CrAPO-5 Primogels:Suspension is made with water in boehmite, later by chromic nitrate water dissolution
Afterwards, it is added in boehmite suspension, is stirred in suspension;Later, it under stirring, is added dropwise
Volumetric concentration is 80~85% phosphoric acid, and after continuing 0.9~1.1h of stirring after adding, three second are added dropwise in the state of stirring
Amine continues 1.9~2.1h of stirring after adding, obtain CrAPO-5 Primogels;
Wherein, the Al in chromic nitrate, boehmite2O3、H3PO4, triethylamine and water the molar ratio of total dosage be n:(1-n):
1:0.74~0.76:M, wherein n=0.03~0.09, m=1.00~1.22;Total dosage of the water is institute in boehmite
The amount of the crystallization water contained, the amount that boehmite is made to water used in suspension with by the amount of chromic nitrate dissolving water used it
With.
