Description
The invention belongs to the medical oxygen technical field, particularly adopt SPC-D to make reagent, the oxygenous prescription of decomposition reaction takes place in water under the effect of catalyzer.
Before the present invention, the method for existing several chemical oxygen generations.The key problem in technology of chemical oxygen generation is to adopt the appropriate means controls reaction speed, produces oxygen speed more uniformly in the hope of obtaining, and when satisfying the use needs, improves the utilization ratio of oxygen.USP4,548,730 provide a kind of method that adds the salt hydrate (as subsulphate, thiosulphate and hydrophosphate etc.) with heat absorption capacity in reactant to come the conditioned reaction liquid temp, to reach the purpose of controls reaction speed.Its shortcoming is that drug dosage is big, and the cost height if the oxygen producing agent SPC-D is packed with heat-sink material, also may influence the stability of oxygen producing agent.The decomposition reaction that WO86/02063 provides a kind of method that adds Sodium peroxoborate in SPC-D to slow down oxygen producing agent, controls reaction speed prevents to react strong.Because the decomposition temperature of Sodium peroxoborate is higher, when therefore using at a lower temperature, the speed of response in later stage is slow excessively, so that not thorough at the oxygen time that the puts internal reaction of expection.EP0093938 provides a kind of and catalyzer (as Manganse Dioxide etc.) is made the water-soluble slow-releasing particle with different release rate has regulated the speed of producing oxygen and putting oxygen, makes needed catalyzer after the particle of different release rate is mixed by a certain percentage.This granules of catalyst is with after water mixes, though can progressively discharge catalyzer by its original speed, the decomposition reaction that prevents oxygen producing agent is too fast, but along with discharging progressively increasing and the continuous rising of reacting liquid temperature of catalytic amount in the reaction solution, the speed of response in its later stage is still wayward.The manufacture craft more complicated of the granules of catalyst of this different release rate, the also corresponding raising of cost.In addition, CN86104506A adopts Sodium peroxoborate to make oxygen producing agent, and Manganse Dioxide is catalyzer, and potassium permanganate is accelerator, and water glass is a moderator.This method provides the medicine of three kinds of controls reaction speed, is decided according to different situations by the user to add which kind and add how many amounts, operate cumbersome, and, if grasp badly, cause a deviation easily.Invented a kind of new safe oxygen producing agent (solid oxygen) prescription for overcoming in the prior art with defective and deficiency.
The objective of the invention is: a kind of safe oxygen producing agent (solid oxygen) is provided, and by the composite catalyst formulating of recipe, the control chemistry produces the speed of response in the oxygen process, in the hope of reaching even product oxygen, when satisfying the use needs, improves the utilization ratio of oxygen.
Main points of the present invention are: a kind of safe oxygen producing agent (solid oxygen); it adopts SPC-D to make reagent; under the effect of catalyzer; decomposition reaction takes place and produces oxygen in Yu Shuizhong; oxygen level and oxygen purity meet the state-promulgated pharmacopoeia regulation; it is characterized in that used catalyzer is by Manganse Dioxide, kaolin and be loaded with the composite catalyst that the granulated active carbon of Manganse Dioxide is formed.
The safe oxygen producing agent (solid oxygen) that the present invention proposes is made up of A agent and B agent two portions, and the A agent is a SPC-D, and the B agent is by Manganse Dioxide, kaolin and is loaded with the composite catalyst that the granulated active carbon of Manganse Dioxide is formed.Controls reaction speed discharges oxygen with relative constant speed effectively.
Manganse Dioxide is made Powdered, increases surface in contact, strengthens katalysis, can improve initial product oxygen speed significantly, satisfies the needs of first aid, the also corresponding consumption that reduces Manganse Dioxide.Powdered Manganse Dioxide is suspended in reaction process in the reaction solution, helps the speed of response in mild later stage.The granularity of Manganse Dioxide is below 60 orders.
Pulverous kaolin has good dispersiveness in water, be evenly distributed in reaction in the middle of the mixture of SPC-D and Manganse Dioxide composition, also can play the effect of mild speed of response.Kaolinic granularity is below 60 orders.
Granulated active carbon makes the micropore surface of gac carry the superfine Manganse Dioxide of last layer, thereby has catalyst action by suitable chemical treatment (as handling till the absorption of granulated active carbon reaches capacity with potassium permanganate solution).Because activated carbon granule proportion is less; progressively rise to liquid level in the reaction process or be suspended in the reaction solution; thereby weakened its katalysis; help controls reaction speed; especially produce the oxygen later stage,, cause product oxygen too fast easily along with reacting liquid temperature raises; be loaded with the granulated active carbon rising liquid level of Manganse Dioxide, help mild speed of response.
In the composite catalyst, Manganse Dioxide, kaolin and be loaded with the uniform mixing such as granulated active carbon of Manganse Dioxide, three's ratio is 1: 0.5-2: 1-3
