Embodiment 1

[0026] Present embodiment provides a kind of Omethoate aromatics-free emulsifiable concentrate, prepares materials by following weight percentage:

[0027] Omethoate 10%,

[0028] Emulsifier 5%,

[0029] Methyl oleate topping up.

[0030] The omethoate-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 omethoate to 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 well to obtain omethoate-free aromatics emulsifiable concentrate.

Embodiment 2

[0035] Present embodiment provides a kind of Omethoate aromatics-free emulsifiable concentrate, prepares materials by following weight percentage:

[0036] Omethoate 18%,

[0037] Emulsifier 5%,

[0038] Methyl oleate topping up.

[0039] The preparation steps of the Omethoate aromatics-free emulsifiable concentrate of the present embodiment are the same as in Example 1.

Embodiment 3

[0041] Present embodiment provides a kind of Omethoate aromatics-free emulsifiable concentrate, prepares materials by following weight percentage:

[0042] Omethoate 40%,

[0043] Emulsifier 5%,

[0044] Methyl oleate topping up.

[0045] The preparation steps of the Omethoate aromatics-free emulsifiable concentrate of the present embodiment are the same as in Example 1.

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 [0001] The invention relates to the field of pesticide emulsifiable concentrate, in particular to an omethoate-free aromatic hydrocarbon 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 ob...
