Abstract
A compound oxydol tablet for sterilizing, disinfecting, washing, bleaching and supplying oxygen is prepared from percarbonyl amine and synergistic I as main raw material, and adding stabilizer, coating agent, synergistic and diluent. Its advantages are high activity and stability, low cost, high effect and low toxin.
Description
The present invention relates to compound dioxygen tablet and method for making thereof.Compound dioxygen tablet is to be the full dissolubility tablet that primary raw material is made with percarbamide and synergist I.Percarbamide is to be the crystallization hydrogen peroxide of carrier with the carbonic acid amide, and it is soluble in water, and its aqueous solution has the character of hydrogen peroxide and carbonic acid amide concurrently.Because it contains the H of anhydrous combination
2O
2, the water-soluble character that just has later hydrogen peroxide is so he has a lot of purposes: sterilization, detergent bleach, oxygen supply etc.Can be widely used in health care, weaving papermaking, the various aspects of agriculture and animal husbandry aquatic products and people's life.
The same with other peroxide, the less stable of percarbamide, overheated and when making moist resolution enlarge markedly, even airtight original packaging under 50 ℃ of conditions, stored one month, 100% decomposition, this has just limited the application of percarbamide.Day disclosure speciallys permit clear 62-252500 and clear 62-280298 once wanted to address this problem, but does not obtain promising result.Purpose of the present invention is exactly in order to address this problem, and produces stable, percarbamide product efficiently, and can reach 1 year the storage period of product.
The present invention is achieved in that the purification of 1. raw material carbonic acid amides
Owing in the raw material carbonic acid amide heavy metal ion such as a spot of Fe, Cu, Mn are arranged, hydrogen peroxide and percarbamide are decomposed, in order to improve the stability of product,, adopt zeolite column to carry out ion exchange and remove at first with the heavy metal ion in the raw material carbonic acid amide.2. percarbamide is synthetic
From reaction equation as can be known, the actuating quantity of carbonic acid amide and hydrogen peroxide is 1: 1 (mol ratio) in theory, in fact hydrogen peroxide wants the excessive product active oxygen that could guarantee that higher content and higher yield are arranged, proportioning is that 1: 1.1 ∽ 1.2 is advisable, reaction temperature is controlled at 5 ∽ and is advisable for 20 ℃, and the reaction time was advisable with 1 ∽ in 1.5 hours.To add a spot of stabilizing agent (organic phosphine and ammonia carboxylic complexant etc.) after the reaction, the heavy metal ion of trace in the further chelatropic reaction liquid, stirred ten minutes, add a spot of coating agent (surfactant and hydrophobicity polyalcohols) again, stirred again ten minutes, vacuum filtration, low temperature (＜35 ℃) is drying to obtain the percarbamide crystalline powder.3. film-making
Percarbamide can direct tablet compressing.In order to improve activity, add synergist I.With pregelatinized starch etc. the percarbamide crystalline powder directly is pressed into tablet with dry method again.
Tablet formulation: 100 parts of percarbamides, synergist I35 part, 20 parts of pregelatinized starchs, crystallite
15 parts of celluloses, 5 parts of superfine silica gel powders, 5 parts of stearic acid.
Method for making: above-mentioned material is placed blender, mix, cross 40 mesh sieves, 2 ∽ 3 times,
With the direct compressing dry granulation of this mixture.4. pack
Because the susceptibility of percarbamide, Jie Chu material must be nonactive with it, and Bao Zhuan seal will be got well simultaneously, so adopt aluminum-plastic packaged (two aluminium packings add the plastic film packing).
Embodiment:
To adopt the zeolite exchange post to exchange, removed 100 gram carbonic acid amide saturated solutions of heavy metal ion, be added to and adorn 150ml 50% concentration H
2O
2The flask of 500ml in, 15 ℃ ± 5 ℃ stirring reactions one hour, add 0.5 gram EDTA again and stirred 10 minutes, add 0.5 gram polyacrylic resin again, continue to stir ten minutes, solution is cooled to 5 ℃, vacuum filtration, 35 ℃ of dry down crystalline powders.Add 35 gram synergist I again, 40 gram pregelatinized starchs, 5 gram stearic acid, directly compressing dry granulation adopts the two aluminium packings of monolithic, gets product.
Claims (3)
1. compound dioxygen tablet and method for making thereof, it is synthetic by the carbonic acid amide of sloughing heavy metal ion through zeolite column and hydrogen peroxide, adds directly compressing dry granulation such as certain amount of stabilizer, coating agent, synergist, thinner again, two aluminium packings.It is characterized in that: earlier slough heavy metal ion in most of carbonic acid amide, in reactant liquor, add the heavy metal ion of the trace in the EDTA chelatropic reaction liquid again with zeolite; In reactant liquor, add coating agent polyacrylic resin, adopt the plastic-aluminum airtight package again, thereby improved the stability of product greatly.
2. according to the described compound dioxygen tablet of claim 1, its feature also is: the raw material proportioning carbonic acid amide of percarbamide synthetic reaction: H
2O
2=1: 1.1 ∽ 1.2,20 ℃ of reaction temperature 5 ∽, 1 hour reaction time.
3. according to the described compound dioxygen tablet of claim 1, its feature also is: added synergist I in the tablet formulation, used pregelatinized starch etc. to be auxiliary material simultaneously, thereby guaranteed the premium properties of compound dioxygen tablet.
