Abstract
The invention discloses an omethoate aromatic-free emulsifiable concentrate and a preparation method thereof. The omethoate aromatic-free emulsifiable concentrate is made from the following materials according to parts by weight: 10-40% of omethoate, 5-20% of an emulsifying agent, and the balance of methyl oleate. After being mixed well in the invention, the methyl oleate and the emulsifying agent can well dissolve crude omethoate, and the obtained emulsifiable concentrate has good stability and dispersity; a benzene solvent in the emulsifiable concentrate is replaced with methyl oleate, thus reducing usage of solvents, such as benzene, methyl oleate and xylene and reducing the harm of benzene solvents to environment and human health; the methyl oleate is widely resourceful and low in cost, thus reducing the cost of the emulsifiable concentrate.
Description
Technical field
The present invention relates to emulsifiable concentrates for agricultural chemicals field, particularly relate to a kind of omethoate without aromatic hydrocarbons cream and preparation method thereof。
Background technology
Current farm chemical emulsion preparation is the formulations of pesticide that China is traditional, accounts for 40% in various dosage forms, and in annual production more than in 19 kinds of pesticidal preparations products of 5 kilotons, having 11 kinds of Pesticidal products is cream dosage form, accounts for the 60% of sum。The primary solvent used in emulsifiable concentrates for agricultural chemicals is benzene,toluene,xylene, but a large amount of use of benzene, toluene and dimethylbenzene creates many problems, such as benzene, toluene and dimethylbenzene are irritant to skin, mucosa, central nervous system is had anesthetic action, sucks higher concentration in the short time and may occur in which the obvious stimulation symptom of eyes and upper respiratory tract；And often in contact with the synthesis of human deoxyribonucleic acid can be suppressed, cause chromosome mutation, destroy hemopoietic system, leukemogenesis；Benzene, toluene and dimethylbenzene dissolubility in water is little, therefore floating or be distributed in the water surface in oily, causes Fish and other aquatile dead。Additionally, toluene and dimethylbenzene also have stronger volatility and inflammability, in transport and use procedure thereof, there is bigger potential safety hazard。
But at present make the cream preparation of solvent with toluene, dimethylbenzene to be still widely used, this is mainly such cream preparation and is better than other preparation in drug effect, such as wettable powder etc., therefore some special insects are being prevented and treated, such as the aspect such as coccid, aleyrodid is better than other dosage form, and it is becoming present aspect also superior to dosage forms such as water dispersible granules, therefore cream or the formulations of pesticide that China commonly uses at present。Therefore, research and development substitute the hypotoxicity of benzene in cream, toluene and dimethylbenzene, the solvent that environmental hazard is little is very urgent。
Methyl oleate, has another name called octadecenic acid methyl ester, for pale yellow transparent oily liquids, can be miscible in water with dehydrated alcohol, ethanol, and these product are the intermediate of detergent, emulsifying agent, wetting agent and stabilizer。Methyl oleate is a kind of material that nature is very general, content is higher, it is common to be present in the oil substances in plant seed such as Semen Sesami, Semen Brassicae campestris, Semen arachidis hypogaeae, Semen Maydis, camellia oleosa seed, Semen Glycines etc., is also one of the main component of some Animal fat class materials。Methyl oleate can also have methanol and oleic acid to obtain through esterification, its method is: by oleic acid and methanol mixed, add catalyst concentrated sulphuric acid or p-methyl benzenesulfonic acid, it is heated to reflux 10h, cooling, being neutralized to pH value with Feldalat NM is 8 ~ 9, washes with water to neutrality, carry out decompression distillation after drying through anhydrous calcium chloride, obtain methyl oleate。Owing to methyl oleate source is wide, nontoxic and environmental hazard is little, it is substitute the ideal solvent of benzene, toluene and dimethylbenzene in cream。
But when adopting methyl oleate to replace the benzene in cream, toluene and dimethylbenzene, the emulsifying agent of different former pharmacopoeia apoplexy due to endogenous wind cream preparations is not suitable for methyl oleate, it is necessary to research and development are applicable to the emulsifying agent of methyl oleate。
Summary of the invention
It is an object of the invention to provide a kind of originate wide, nontoxic and to the little omethoate of environmental hazard without aromatic hydrocarbons cream。
Further object is that the preparation method providing omethoate without aromatic hydrocarbons cream。
The above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of omethoate, without aromatic hydrocarbons cream, is got the raw materials ready by following percentage by weight:
Omethoate 10% ~ 40%,
Emulsifying agent 5% ~ 20%,
Methyl oleate polishing。
Preferably, described emulsifying agent percentage by weight is 10%。
Preferably, described methyl oleate percentage by weight is 88.2%。
In order to better dissolve former medicine, described emulsifying agent is one or more in farm chemical emulgent, emulsification agent and diesel oil emulsifier。
Preferably, described farm chemical emulgent include 100#, 500#, 1601,1602, OP-7, OP-10,600,600-1,600-2,600-3, BY-110, BY-112, BY-120, BY-130, BY-140,400,403。
Preferably, described emulsifying agent be farm chemical emulgent monomer 100#, 500#, 1601, OP-7, OP-10, emulsification agent mixture。
Preferably, described emulsification agent is formed by multiple the moon/nonionic surfactant and additive compound。
Described omethoate, without aromatic hydrocarbons cream, is prepared according to the following steps:
(1) emulsifying agent is added in appropriate methyl oleate, mix homogeneously；
(2) former for omethoate medicine is added in the solution of step (1) gained, mix homogeneously；
(3) remaining methyl oleate is added in the solution of step (2) gained, mix homogeneously, obtain omethoate without aromatic hydrocarbons cream。
Beneficial effects of the present invention: after the methyl oleate in the present invention mixes with emulsifying agent, it is possible to the former medicine of dissolved oxygen Rogor well, and the cream obtained has good stability and dispersibility；The present invention adopts methyl oleate to be substituted into the benzene-series solvent in oil, thus decreasing the consumption that makes of benzene in cream, toluene and dimethylbenzene equal solvent, and decreases the harm that environment and human health are caused by benzene-series solvent；And methyl oleate wide material sources, cost are low, thus reducing the cost of cream。
