Description
Technical field
The present invention relates to a kind of device that improves product stability, be specially the former medicine floating stable of a kind of Hostathion taking silica gel as adsorbent bag.
Background technology
Hostathion (Triazophos), chemical name: O, O-diethyl-O-(1-phenyl-1,2,4-triazole-3-group) thiophosphate.Sterling is sundown liquid, 0～5 DEG C of fusing point, and when 1.247,30 DEG C of proportions, vapour pressure is 0.387MPa, the solubility 20 DEG C time in water is 35mg/L; Dissolve in most of organic solvents.Stable to light, in acid, alkaline media, be hydrolyzed 140 DEG C of decomposition.Hostathion is broad spectrum insecticide and nematicide.Insect is had and tagged and stomach poison function, and permeability is strong, and ovicidal action is obvious.Be widely used in the control of paddy rice, cotton, wheat, corn, fruit and vegetables primary pest, antagonism bollworm and red spider have good preventive effect.But the former medicine of Hostathion is unstable, under heat storage and normal temperature storage condition, be prone to the phenomenons such as crystallization, layering, poor transparency, in 1 year, resolution ratio can be up to 5%～20%, had a strong impact on the stability of former medicine and preparation thereof.For improving the stability of Hostathion, normally in the former medicine of Hostathion, add stabilizing agent, as acetic anhydride, triphenyl phosphate, phthalic anhydride, epoxychloropropane, thuja acid sodium etc., these stabilizing agents can reduce the moisture content in the former medicine of Hostathion with water generation hydrolysis, show certain stablizing effect.But the addition of these stabilizing agents is larger, common more than 2%, be equivalent to introduce impurity in former medicine, reduce the concentration of Hostathion.Particularly acetic anhydride, triphenyl phosphate, phthalic anhydride etc. have produced corresponding organic acid with after water reaction, and the pH value of Hostathion is significantly reduced.Experiment shows, the stability of Hostathion and its pH value, water content are closely related.PH value is too high or too low, too high its stability that all will reduce of moisture content.Although the former medicine of the Hostathion on market has added stabilizing agent, because stabilizing agent has produced corresponding acid in storage process, as acetic anhydride will react with water generation acetic acid in when storage, the hydrolysis that the latter can catalysis Hostathion, has reduced the stability of Hostathion.In addition, stabilizing agent can reduce the water content in the former medicine of Hostathion, but can not reduce the content of residual catalyst wherein and excessive diethylaluminum monochloride content, the former medicine of Hostathion thermodynamic stability when experiment in the time carrying out 54 DEG C, generally about 14 days, just occur precipitation.
Summary of the invention
The invention provides a kind of method with cursory stabilization pocket and the former medicine of stable Hostathion that improves agricultural chemicals Hostathion stability.
The former medicine floating stable of a Hostathion bag taking silica gel as adsorbent, comprises the stabilization pocket made from nonwoven, the silica gel in stabilization pocket after parcel activation, and the surrounding of stabilization pocket is connected with cursory, and cursory buoyancy remains on stabilization pocket on the upper strata of the former medicine of Hostathion.
As optimal way, described nonwoven includes but not limited to by macromolecular material cloth, nonwoven or gauze.
As optimal way, described cursoryly include but not limited to that plastics are cursory, bamboo, cork in cursory with one.
As optimal way, the using method of described stabilization pocket is, use separately stabilization pocket to stablize the former medicine of Hostathion, also can be both to have added stabilization pocket in the former medicine of Hostathion, also in the former medicine of Hostathion, add stabilizing agent, stabilizing agent comprises but is not limited to acetic anhydride, triphenyl phosphate, 3-chloro-1,2 cyclopropane, thuja acid sodium.
Advantage of the present invention is.
1, the impurity in the former medicine of Hostathion can be effectively removed, Hostathion hydrolysis, alcoholysis will be stoped.In the former medicine of Hostathion, through gas phase and efficient liquid phase chromatographic analysis, discovery major impurity is water, ethanol, catalyst, unreacted O, the O of O-diethyl sulfo-phosphoryl chloride and hydrolysis, O-diethyl D2EHDTPA, these impurity can make Hostathion hydrolysis or the hydrolysis of catalysis Hostathion.As, in the time having water to exist, Hostathion is hydrolyzed to O by water, O-diethyl D2EHDTPA and benzene azoles alcohol, and in the time having ethanol to exist, Hostathion is hydrolyzed to benzene azoles alcohol and O by alcohol, and O-diethyl sulfide is for etherophosphoric acid.If there is excessive unreacted O in the former medicine of Hostathion, O-diethyl sulfo-phosphoryl chloride, they are by generation HCl gas and make Hostathion be acid, thus catalysis hydrolysis or the alcoholysis of Hostathion.Through overtesting, the silica gel of certain pore size can adsorb these impurity effectively.Silica gel selectively absorbs strong polar substances, and first silica gel adsorb impurity and do not adsorb the Hostathion of low pole.
2, this stabilization pocket floats over the upper strata of Hostathion, can guarantee the moisture content on the former medicine of Hostathion top in bucket or ethanol, O, and O-diethyl sulfo-phosphoryl chloride etc. is absorbed fully fast.Because Hostathion proportion is 1.247, the proportion of water is 1, and the proportion of ethanol is 0.79, and while leaving standstill, because of Action of Gravity Field, moisture content will upwards be assembled and part is separated out, and the concentration of the impurity such as ethanol also can be on upper strata because gathering raises.Float over the top of the former medicine of Hostathion by cursory buoyancy instead of allow stabilization pocket sink to bottom thering is adsorbing stabilization pocket, will be to greatest extent the various impurity such as quick adsorption water, ethanol.
3, when silica gel is by after the impurity absorption such as most of water, alcohols in former Hostathion medicine, stabilizing agent acetic anhydride etc. will can not produce compared with highly acid because of hydrolysis, under neutrality and utmost point solutions of weak acidity, the stability of Hostathion is higher, and this demonstrates between the stabilizing agent adding in silica gel in stabilization pocket and the former medicine of Hostathion collaborative stabilization.
