Abstract
A synthesis method of a cypermethrin luring type microemulsion is disclosed. The microemulsion is prepared by an emulsification water-to-oil method after raw materials are mixed. The raw materials are prepared by mixing following materials by weight: 2-4% of cypermethrin, 8-10% of a solvent, 22-26% of a surfactant and 6-9% of a co-surfactant, with the balance being deionized water, wherein the surfactant is prepared by mixing sodium saccharin and glucose ester according to a molar ratio of 1:1.
Description
Technical field
The present invention relates to a kind of cypermethrin and lead to the synthetic method of type microemulsion.
Background technology
Microemulsion be water and with the immiscible agricultural chemicals liquid of water, under the effect of surfactant and cosurfactant, forming isotropic, thermodynamically stable, outward appearance is transparent or semitransparent, single-phase mobile dispersion.
Microemulsion drop is trickle, and forming suitable microemulsion can spontaneous formation and do not condense, and can keep higher stability, the single-phase homogeneous of system, good fluidity." single-phase " mean not stratified, without crystallization, without liquid crystal, without precipitation, no suspended substance.Microemulsion is thermodynamic stable system, very little at the contact-making surface of micella Pesticides molecule and water, is conducive to improve the stability of hydrolabil agricultural chemicals in water, improves without adding tackifier that it is stable again.Agricultural chemicals, generally will be through storing for a long time after preparation until before using, and requires can keep uniform state after thin up and simple agitation, to pass through atomizers spray when use.
Also lack at present the compound method of universally recognized science for the preparation of microemulsion.Generally the compound method of application remains rule of thumb by two kinds of surfactants of different nature, normally anion surfactant and non-ionic surface active agent carry out mixture, determine kind and the consumption of surfactant, detect according to the apparent phenomenon and index the kind and the consumption etc. that screen again cosurfactant, finally determine formula composition.
Summary of the invention
technical problem
In view of this, the technical problem to be solved in the present invention is to provide a kind of cypermethrin of simple and fast to lead to the synthetic method of type microemulsion.
solution
In order to solve the problems of the technologies described above, the invention provides a kind of cypermethrin and lead to the synthetic method of type microemulsion, after will raw material mixing, to make by emulsified water oiling, described raw material is mixed by following components by weight percentage: cypermethrin 2～4%; Solvent 8～10%; Surfactant 22～26%; Cosurfactant 6～9%, and surplus deionized water, wherein 1:1 is composite in molar ratio forms by saccharin sodium, glucose ester for surfactant.
Preferably, described solvent is 2-butanone.
Preferably, described cosurfactant is n-butanol.
beneficial effect
The cypermethrin that the invention provides a kind of simple and fast is led to the synthetic method of type microemulsion.
Embodiment
Saccharin sodium, claims again soluble saccharin, soluble in water, is commonly called as asccharin, is organic chemical industry's sintetics.Colourless crystallization or slightly albescent crystalline powder, odorless or micro-ly have fragrance, is sweet taste, and sugariness is 500 times of left and right of sucrose, a little less than heat-resisting and alkali tolerance, is also a kind of nontoxic, empty calory, without nutrition and again not by the sweetener of animal and absorption of human body.
Glucose ester is that one is led to type surfactant, the up-and-coming youngster in surfactant family, have safe, nontoxic, to skin the non-stimulated and feature such as biological degradability absolutely, along with the enhancing of people's uphold nature and environmental consciousness, biosurfactant will have more wide application prospect, and likely becomes substitute or the upgrading product of synthetic surfactant.This microemulsion thermodynamic stability is good; be easy to adhere to, soak, sprawl and permeate at crops blade; can dissolve insect wax quality guarantee sheath and cause insect death by suffocation; can effectively protect pest natural enemy, and nontoxic to people, animal, because it has unique insecticidal mechanism; insect can not develop immunity to drugs; be more suitable in the application proportion expanding in following integrated pest management strategy, the direction of the industry ecological revolution from now on that fits like a glove, has good market prospects good.
Embodiment
Former medicine (cypermethrin) 3%; Solvent (2-butanone) 9%; Surfactant (saccharin sodium, glucose ester) 24%; Cosurfactant (n-butanol) 10%; Deionized water 54%, the ratio of wherein carrying out two kinds of composite surfactant saccharin sodiums, glucose ester carries out compositely all can according to 1:1.
The type microemulsion of leading to of preparation the experiment proved that its heat storage stability, cold storage stability, and ageing stability is all better, has placed 2 years its cypermethrin content and has degraded lower.
Lead to type microemulsion system just preparing and placing after a period of time, cypermethrin structural property wherein does not all change.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
