Abstract
The invention relates to a preparation method of an ampholytic surfactant composition. Particularly, the composition comprises 3.8-4.0 kg of an active matter A that is myristyl 2 hydroxyethyl amine oxide, 3.8-4.0 kg of an active matter B that is dodecyl alanine, 8.7-9.4 kg of a solvent A that is water, 3.3-3.8 kg of a solvent B that is ethyl alcohol and 0.2-0.3 kg of an accessory ingredient C that is vegetable oil. For the preparation method disclosed by the invention, a large number of organic solvents are saved, waste is avoided, and pollution of the organic solvents to environment due to the use of pesticides is avoided.
Description
Technical field:
The present invention relates to a kind of preparation method of amphoteric surfactant composition.
Background technology:
Amphoteric surfactant, refers to the surfactant simultaneously with yin, yang two kinds of ionic natures.From its structure, the existing cation be connected with hydrophobic group, also has anion.It is a kind of surfactant of mildness.Amphoteric surfactant molecule and single anionic, cationic different, have acidic groups and basic group in one end of molecule simultaneously.Acidic groups is mostly carboxyl, sulfonic group or phosphate, and basic group is then amido or quaternary ammonium group, can with anion, nonionic surface active agent mixture, can acid and alkali resistance, salt and alkali salt.It can be used alone as insecticides adjuvant, and the mixed type auxiliary agent obtained with anionic surfactant mixture, has more excellent performance, but due to technical difficulty large, China cannot break through in this field always.
Summary of the invention:
The object of the present invention is to provide a kind of preparation method of amphoteric surfactant composition.
Comprise following content:
A preparation method for amphoteric surfactant composition, comprises the following steps:
(1) active matter A myristyl dihydroxy ethyl amine oxide 3.8-4.0kg, active matter B dodecyl alanine 3.8-4.0kg is taken by constitutive material; Solvent orange 2 A water 8.7-9.4kg, solvent B ethanol 3.3-3.8kg; Auxiliary agent C vegetable oil 0.2-0.3kg;
(2) alleged for step (1) solvent orange 2 A and active matter A are joined successively in mixing kettle, stir, be then warming up to 35 DEG C under normal pressure, continue to stir 30min, obtain mixture A, mixing kettle is cooled to 20 DEG C;
(3) alleged for step (1) solvent B and active matter B is joined in mixing kettle successively, stir under normal pressure, be then warming up to 35 DEG C, continue to stir 30min, obtain mixture B;
(4) mixture B pump is evacuated in the mixing kettle in step (2), then in normal pressure lower 25 DEG C, stirs, then the auxiliary agent C alleged by step (1) is added, until it all dissolves, continue to stir 30min, obtain amphoteric surfactant composition.
Beneficial effect:
The present invention not only can solve the problems such as pesticidal preparations preparation cost is high, environmental pollution is large, benefit is low.And can effectively reduce crops residual toxicity, and strengthen crops pesticide supplying effect and Nai Yu and drought-resistance ability, for promote the upgrading of China's surfactant product and realize peasant increasing both production and income, reduce the effect that pesticide pollution has play staff's weight.Save a large amount of organic solvent, avoid waste, when avoiding because of Pesticide use, organic solvent is to the pollution of environment.
Embodiment:
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Embodiment 1: a kind of preparation method of amphoteric surfactant composition, comprises the following steps:
(1) active matter A myristyl dihydroxy ethyl amine oxide 3.8-4.0kg, active matter B dodecyl alanine 3.8-4.0kg is taken by constitutive material; Solvent orange 2 A water 8.7-9.4kg, solvent B ethanol 3.3-3.8kg; Auxiliary agent C vegetable oil 0.2-0.3kg;
(2) alleged for step (1) solvent orange 2 A and active matter A are joined successively in mixing kettle, stir, be then warming up to 35 DEG C under normal pressure, continue to stir 30min, obtain mixture A, mixing kettle is cooled to 20 DEG C;
(3) alleged for step (1) solvent B and active matter B is joined in mixing kettle successively, stir under normal pressure, be then warming up to 35 DEG C, continue to stir 30min, obtain mixture B;
(4) mixture B pump is evacuated in the mixing kettle in step (2), then in normal pressure lower 25 DEG C, stirs, then the auxiliary agent C alleged by step (1) is added, until it all dissolves, continue to stir 30min, obtain amphoteric surfactant composition.
Application test:
For 5.5% pyrethrins aqueous emulsion:
Ethanol 12%; 5.5% pyrethrins; Amphoteric surfactant 5% of the present invention; Thickener 0.3%; Antifreezing agent 6%; Defoamer 0.2%; Deionized water supplies 100%
Better by the chemical stability of the formulated pesticidal preparations of amphoteric surfactant, resolution ratio is lower, and through the placement of 30 days, resolution ratio was only 1.05%, can steady in a long-termly exist in water.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
