Embodiment 1

[0026] This embodiment provides a kind of clethodim aromatics-free emulsifiable concentrate, which is prepared according to the following weight percentages:

[0027] Clethodim 12%,

[0028] Emulsifier 5%,

[0029] Methyl oleate topping up.

[0030] The clethodim aromatic-free emulsifiable concentrate of the present embodiment is prepared according to the following steps:

[0031] (1) Add the emulsifier to an appropriate amount of methyl oleate and mix well;

[0032] (2) Add the original drug of clethodim into the solution obtained in step (1), and mix well;

[0033] (3) Add the remaining methyl oleate to the solution obtained in step (2), and mix evenly to obtain clethodim aromatics-free emulsifiable concentrate.

Embodiment 2

[0035] This embodiment provides a kind of clethodim aromatics-free emulsifiable concentrate, which is prepared according to the following weight percentages:

[0036] Clethodim 24%,

[0037] Emulsifier 5%,

[0038] Methyl oleate topping up.

[0039] The preparation steps of the clethodim aromatics-free emulsifiable concentrate of this embodiment are the same as those in Embodiment 1.

Embodiment 3

[0041] This embodiment provides a kind of clethodim aromatics-free emulsifiable concentrate, which is prepared according to the following weight percentages:

[0042] Clethodim 26%,

[0043] Emulsifier 5%,

[0044] Methyl oleate topping up.

[0045] The preparation steps of the clethodim aromatics-free emulsifiable concentrate of this embodiment are the same as those in Embodiment 1.

Abstract

The invention discloses clethodim aromatic-free missible oil and a preparation method thereof. The clethodim aromatic-free missible oil is prepared from, by weight, 12%-30% of clethodim, 5%-20% of emulsifier and the balance methyl oleate. According to the clethodim aromatic-free missible oil and the preparation method thereof, methyl oleate is mixed with the emulsifier, the clethodim raw material can be well dissolved, and the obtained missible oil has better stability and dispersity; the methyl oleate is adopted to replace benzene solvent in the missible oil, the usage amount of solvent such as benzene, methylbenzene and xylene in the missible oil is reduced, and damage of the benzene solvent to the environment and human health is reduced; the methyl oleate is wide in source and low in cost, and therefore the cost of the missible oil is reduced.

Description

technical field [0001] The invention relates to the field of pesticide emulsifiable concentrates, in particular to a clethodim aromatic-free emulsifiable concentrate and a preparation method thereof. Background technique [0002] At present, pesticide emulsifiable concentrate preparations are the traditional pesticide formulations in my country, accounting for about 40% of the various formulations. Among the 19 pesticide formulation products with an annual output of more than 5,000 tons, 11 pesticide products are emulsifiable concentrate formulations, accounting for 60% of the total. . The main solvents used in pesticide emulsifiable concentrates are benzene, toluene, and xylene, but the large-scale use of benzene, toluene, and xylene has produced many problems, such as benzene, toluene, and xylene are irritating to the skin and mucous membranes, and are harmful to the central nervous system. Anesthesia, short-term inhalation of higher concentrations can cause obvious irrita...
