Embodiment 1

[0041] (1) Material preparation: select liquid levulinic acid with a content of 95% for use; prepare a solution with a concentration of 30% potassium hydroxide, and wait for it to cool for later use.

[0042] (2) Reaction: Put liquid levulinic acid into the reaction kettle, then slowly add lye until the pH value is 6.5-8.2, control the reaction temperature at 80-90°C; react for 3.5 hours.

[0043] (3) Water and side reaction products are distilled out under reduced pressure, and the distillation temperature is controlled at 75-90°C.

Embodiment 2

[0045] (1) material preparation: select levulinic acid and potassium hydroxide with a content of 95% for use, and then solid alkali is mixed with a concentration of 45% solution, and it is for subsequent use after cooling;

[0046] (2) Reaction: Put levulinic acid into the reaction kettle, then add lye, control the reaction temperature at 70°C to 75°C, and continue the reaction for 3.5 hours;

[0047] (3) Water and side reaction products are distilled out under reduced pressure, and the distillation temperature is controlled at 90-100°C.

[0048] The preparation method of above-mentioned plant growth promoter comprises the following steps successively:

Abstract

The invention relates to a plant growth regulator and a preparation method thereof. The plant growth regulator comprises RCOOH and RCOOR, wherein R is C2H5-C6H13, and the characters comprise that 1, the form is a liquid state and the color is brown, 2, the pH value is 6.5-8.2, 3, the product is soluble in water, 4, the specific gravity is 1.30-1.40, and 5, no discomfort odor exists and corrosion and irritating do not exist. The preparation method sequentially comprises: (1) preparing material, wherein levulinic acid having a content of more than or equal to 95% and potassium hydroxide are selected, the solid alkali is prepared into a solution with a concentration of 30-45%, and cooling is performed so as to be spare; (2) carrying out a reaction, the levulinic acid is poured into a reaction kettle, the alkali liquid is added, the reaction temperature is controlled at 70-110 DEG C, and the reaction is continuously performed for 3.5-4.5 h; and (3) carrying out pressure reducing distillation to remove the water and the side reaction product, wherein the distillation temperature is controlled at 75-100 DEG C.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a plant growth regulator and a preparation method thereof. Background technique [0002] Plant growth regulators are a class of substances that have similar physiological and biological effects to plant endogenous hormones. It has been found that the functional substances that regulate plant growth and development include auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinolide, salicylic acid, jasmonic acid and polyamines, etc., which are mainly used in agricultural production It is the first 6 categories. [0003] Two of these categories are described below: [0004] Gibberellin (GA) other names: 920, GA, Qibao. [0005] Preparation: 85% gibberellin crystalline powder, 4% gibberellin emulsifiable concentrate, 40% water-soluble tablet, 40% water-soluble powder. Its action characteristics: gibberellin is a broad-spectrum plant growth regulator. Endogenous gibb...
