Problems solved by technology

[0003] The cyclic esterification method related to the present invention reported in the literature uses concentrated sulfuric acid as a catalyst, and has disadvantages such as corrosion, carbonization, pollution, etc.
P-toluenesulfonic acid is used as a catalyst. Although the amount of methanol is reduced, the amount of catalyst is greatly increased, and it is not easy to recycle.
There are also biomass solid acids used as catalysts, but the amount of methanol and catalysts are more

Embodiment Construction

[0020] Add p-toluenesulfonic acid and soluble starch in a beaker according to m (p-toluenesulfonic acid): m (starch) = 1:2, dissolve with distilled water, then heat until the solution is clear and transparent, then cool to room temperature, and evaporate by rotary evaporator into a viscous colloid, placed in a muffle furnace, and carbonized at 200°C for 8h. Grind immediately after taking out, and then pass through a 80-mesh sieve to obtain a carbon-based solid acid catalyst.

[0021] according to figure 1 After installing the reaction device, a certain amount of oleic acid and a carbon-based solid acid catalyst equivalent to 1.0% oleic acid mass were added to the reactor in sequence, and at the same time, the water bath was turned on for heating, and the temperature of the evaporator water bath was set at 90°C. When the temperature of the reaction water bath reaches 68°C, methanol is added according to the molar ratio of alkyd to 2:1 to start the reaction. Within half an hour...

Abstract

The invention discloses 60wt% of butachlor missible oil prepared from biodiesel and a preparation method thereof. The preparation method comprises catalyst preparation, biodiesel synthesis and 60wt% of butachlor missible oil preparation. In preparation, 65.2 weight parts of a butachlor raw material having the content of 92wt% and 16 weight parts of sodium laurylpolyoxyethene (7) octyl sulfosuccinate having solid content of 62wt% are dissolved in 18.8 weight parts of biodiesel so that the 60wt% of butachlor missible oil is obtained. The preparation method utilizes a carbon-based solid acid catalyst in oleic acid and methanol cyclic esterification for the first time. The catalyst is prepared simply, has a low cost, can be used for oleic acid and methanol cyclic esterification and is suitable for industrialization. The biodiesel obtained by an oleic acid-methanol reaction is used as a solvent of the 60wt% of butachlor missible oil so that the environmental pollution caused by organic solvents such as aromatic hydrocarbons is reduced.

Description

technical field [0001] The invention relates to a method for preparing 60% butachlor emulsifiable concentrate. Background technique [0002] Biodiesel is mainly a fatty acid ester compound produced by esterification or transesterification of long-chain fatty acids such as oleic acid, linoleic acid, and stearic acid, and glycerin fatty acid esters with low-carbon alcohols. With a wide range of chemical functions, it can be directly used to replace the currently used fossil fuels and overcome their shortcomings. In addition, due to its weak toxicity, high flash point, strong solubility, convenient regeneration, easy biodegradation, and safe storage and transportation, biodiesel meets the requirements for solvents in the development of future pesticide formulations, and theoretically has the potential to replace traditional pesticide solvents. The raw materials for biodiesel synthesis can generally be divided into four categories: animal fats, vegetable fats, microbial fats an...
